Now I\'m thinking about a Procomp lift!!

Ok, i went to Procomp's website and was checking out their 6" kit. What do yall think about it? Is it not as good as the Rancho? I like the fact that it is 6" versus the 4" Rancho. plus it solves the auto-tack problem. anyway, im looking forward to any opinions on this kit.......thanks a lot.

Re: Now I\'m thinking about a Procomp lift!!

I don't know much about the procomp stuff other than their skid plate looks cool. I did however help install 2 IFS suspensions last weekend. The fabtech lift for 2001's is a great lift, but a pita to install. The Trailmaster lift for 88 to 98's seemed to be well made. It was some thick and heavy stuff too. Fairly easy to install. Back to procomp, I have heard from some people that their lifts are of low quality and tend to have problems - This is all 2nd and 3rd hand info though, there are several people I have talked to who have this lift and love it. Rancho imho, is going to be about the best simply because of the 1 piece sub frame, but like you I wanted a full 6" when I was looking for lifts. Generally around here people will say that in the 6" lineup the Cepeck lift is the best, then the superlift, then it's a draw between the bunch. I don't think you should just not look at BDS or Trailmaster though as they are both great lifts in my book.

Re: Now I\'m thinking about a Procomp lift!!

I highly recomend SUPERLIFT /wwwthreads_images/icons/smile.gif

By the way Rancho does not make a 6" lift,
they do make a 5.25" lift
that they call a 4" lift
and some shops sell as a 6" lift /wwwthreads_images/icons/crazy.gif
You figure it out ???/wwwthreads_images/icons/laugh.gif

Re: Now I\'m thinking about a Procomp lift!!

Pro Comp is not a true 6" lift. I think mine is more like 5". I haven't broken anything but I've tweaked everything out of alignment and had to have it disassembled/reassembled and welded. I would go with a lift that has a 1 piece subframe.

Re: Now I\'m thinking about a Procomp lift!!

ProComp is junk. Do a search on this board. A few weeks back we discussed their stuff and a lot of bad stuff came up against them. Junk in my opinion.

Rancho's new 4" lift actually is about 5.25", but a lot of places sell it as a 6" lift because with .75" worth of torsion bar cranking you get 6". If I was going to do an IFS lift instead of a solid axle swap (I'm not though) I'd go with either the Rancho for it's 1 peice subframe (BEEF/wwwthreads_images/icons/cool.gif) or the new Tough Country 6" lift that has a 1 peice subframe as well. Haven't heard much about it yet by way of actual owners, but it looks good and from what I've read about the thing it sounds good./wwwthreads_images/icons/smile.gif

Re: Now I\'m thinking about a Procomp lift!!

Pro crap only solves the auto-trac problem by selling you another front driveshaft. One that has a cv joint in it.

I would give you all of my opinions but I don't want to type that long.

Re: Now I\'m thinking about a Procomp lift!!

Well I disagree with all of them, I have a Pro-comp and I like it. I have not had any problems with it and I beat on it. I did weld everything together after I had it aligned though. I am not going to sell this truck or take the lift off so it doesn't matter that it is welded. I have heard crap about all lifts when I researched mine. Except for maybe cepak but they were out of business when I bought my lift. Anyways good luck with whatever you buy.

Re: Now I\'m thinking about a Procomp lift!!

I dont know about ya'll but I have a 6'' pro-comp lift, and I run my truck hard off road. I have bent my frame, destroyed a ranch hand grill guard, broken off my shock hoops, and blown 4 out of my 5 crankshaft bearings, and ripped off my factory shock mounts. I know I wheel hard. I havent had any troubles yet with my pro-comp lift(except the triple shock hoops) , I know its not a one-piece sub-frame, but if I do get problems with it, I will just weld it into one. My neighbor with his 4-6'' rancho lift has had more problems than I have had with his suspension and he wheels about 1/4 of what I do, even my neighbor down the street had a k1500 with a trailmaster 6'' lift and he broke off one his control arms. He is happy with his rancho lift as I am with my pro-comp. The only thing I regret about the pro-comp lift is that the subframe wasnt designed for more clearance as the rancho's and trail master's are, then again I have a full skid plate to cover the bottom side. I just want to see some people post who have had problems with their procomp lift. When I chose my lift, there were 3 things I considered; k1500 owners with the lifts, price, and design.

I know as soon as I run into some problems I will post about it. The main reason I chose pro-comp over the other brands was mainly the deal I got on it. If you can get a great deal, dont pass it up! Thats what I pretty much built my truck on, deals.

Re: Now I\'m thinking about a Procomp lift!!

Rancho doesn't make a 6" kit. Call their tech line and ask. 1-800-GORANCHO.

About 10-15 years ago Rancho came out with this really bad 4" lift that replaced the upper control arms with a set of theirs and didn't drop the diff and control arms down a full 4". So the angles were bad on everything and it was about impossible to align./wwwthreads_images/icons/frown.gif

Now we get into the Rancho history a little bit. A long time ago, like in the late 70's, when the 4x4ing aftermarket was still getting started, Rancho set their company policy that you should not lift a fullsize truck more than 4", a midsize more than 3", and a Suzuki sized truck more than 2" or so for safety's sake. Ever noticed all their lifts are so small? The only one you will ever see listed as taller than 4" is this very kit we are talking about. So over the 10 years or so since Rancho let out their first 4" kit they've been loosing money to all these other companies that are selling 6" lift kits for fullsize GM IFS trucks to people, many of whome are driving around perfectly safely with their 6" lifts and big tires.

So to fix the problems with their first 4" kit they release the new one, with the 1 peice subframe for strength and it also drops down the control arms and steering the full amount./wwwthreads_images/icons/cool.gif However, when you put the kit on your truck and set everything according to Rancho's instructions, the subframe drop is 5.25", the control arms are 5.25", and the steering is 5.25". All with the torsion bars at the stock setting and being perfectly able to maintain a good ride and a good alignment. Hmmmmmmm..................if you call and ask, they'll maintain that it's just a 4" kit./wwwthreads_images/icons/wink.gif/wwwthreads_images/icons/wink.gif

They're just trying to get into the bigger than 4" IFS lift and "I wanna run 35's" market. Which they have successfully done with this kit./wwwthreads_images/icons/cool.gif

A lot of places sell the kit as a 6" kit because all it takes is a .75" crank of the torsions to make it 6". Don't ask the Rancho techs about this though, they'll deny it. I did, and they denied it./wwwthreads_images/icons/wink.gif/wwwthreads_images/icons/laugh.gif

Re: Now I\'m thinking about a Procomp lift!!

Again, call their phone number I listed above and ask. Go to their website: http://www.gorancho.com. No where is a 6" lift kit mentioned. Now, hint hint, nudge nudge, their new 4" kit is very close to 6", and with a little bit of torsion bar tweak it is 6", but no, they don't sell a 6" kit.

*****EDIT******* I was wrong, it's 1-800-574-6257 8am to 7pm EST.

Here's their 4wd suspension site: http://www.gorancho.com/products/4wdsuspension.stm
See a 6" kit? I don't.

Re: Now I\'m thinking about a Procomp lift!!

I promise you Rancho's kit for the 88-98 Trucks/Tahoes/Suburbans is a 6" kit. Go over to http://www.fullsizechevy.com go to the forums section, then the offroad section, search for Rancho Rep, or member name Chris. He is a rancho tech that post's on the forum, and he told me for a fact that the Rancho RS6568 is a 6" lift.

Re: Now I\'m thinking about a Procomp lift!!

Bow unto AJM for he is the all seeing all knowing force in which we call Carpal Tunnel!

Great info with plenty of backup support man!

I wouldn't have argued against that because I already knew, but I couldn't have proved it like that.

Good job
KS2

And bigpun, you're right too, with a little cranking on the t-bars (a safe ammount) it can be a 6" kit. 35's do work in it, and some people referr to it as a 6" kit. But as anyone can tell Rancho calls it a 4" kit.

Re: Now I\'m thinking about a Procomp lift!!

look im tellin ya there is an actual 6 inch kit. yes i do know about cranking the torsion bars on the 4" kit but i have talked to people plus the rancho techs and there is a 6 inch kit. oh and as far as rancho having a tradition or whatever of only goin so high like 4" as their maximum isnt right. the lift they just came out with for the HD's is 5" so that isnt true about their company

Re: Now I\'m thinking about a Procomp lift!!

hey guys,
thanks for all the opinions. I didnt mean to start any arguing about the rancho kits. BUT, that does bring up an interesting question. If the "4" inch kit is actually a 5.25 inch, how do they bring the rear up? If they give u a 4 inch block, wont the rear sag low? Ive seen a few tahoes with this low back end, and i HATE it. I want the truck to be level, or slightly butt-high like the stock tahoes. What does rancho do to make sure the back isnt too low??

thanks and gig 'em,
andy

Re: Now I\'m thinking about a Procomp lift!!

A quote off another board from a Rancho Tech:

The upper and lower control arms, front diff and steering are all dropped 6 inches in the RS6543,RS6555,RS6568,and RS6567

(The torsion bar crossmember is lowered a little less, and there's only a 4 inch rear block in the kit.)

http://64.246.6.99/~admin6/forum/showthread.php?s=&threadid=7922

I don't care if you "think" you are right or not. How many of yall have the kit? If you don't have one, how many of yall know people that have this kit? Want more proof? Hows this?

Agreed, its not a tape measure, but you get the idea.

Re: Now I\'m thinking about a Procomp lift!!

Did you read the 1st reply to the original question?:
Question:
Why does Rancho call their lift kit 4" while the competitors rate theirs as 6" and they are lifted by the same method?

Fabtech and RCD all call theirs 6" and they lift exactly the same way: subrame dropped 6"; replacement spindles that are 6" longer; UCA remains at stock position.

I don't see how anyone could get only 4" out of the Rancho Kit
Answer:
Mainly political, has to do with being part of a larger corporation.

Since at least the '91 catalog we published that we recommended a maximum of 4 inch rise on full size applications, 3 inches on midsize and Toyota, and 2-1/2 inches on Jeeps for safety reasons.

So right now we are forbidden to advertise more than 4 inches, (although our customers don't necessarily follow this)

To be competitive, some of the heights may be a bit "optimistic"

The main reason for the front diff being dropped 6 inches on the older IFS trucks and 4-1/2 and rotated on the newer has to do with accomodate Autotrac with the factory driveshaft rather than indicating a certain amount of lift
This is exactly what AJM is trying to tell you. He is giving the same info that the Rancho tech did. It is a political thing to call it a 4", even though it still measures out closer to 6".

Re: Now I\'m thinking about a Procomp lift!!

Thanks Jax.

Okay, I think I'm just going to lift the proper way. By selling my IFS truck and buying an older truck with a solid axle. For the same amount as a set of 35's and rims, 6" IFS lift and whatever else they want to do to make them fit, 4.56 gears, speedo correction, and whatever else, I can have 3/4 ton axles, 6" of total flexy spring lift, 36" Swampers, rear discs on the 14FF with a Lincoln Locker, and low gears./wwwthreads_images/icons/cool.gif

Re: Now I\'m thinking about a Procomp lift!!

I have the 6" Pro-comp lift and I tend to drive it pretty hard off-road, even though I often regret it when I end up taking that stupid IFS front end to the shop and paying the bill for it. Well I dunno it is usually worth it after a good weekend on the trails. Anyways I love the lift, wouldn't trade it if I could right now. I got it b/c I recieved a good deal, but now I dont regret it at all.
