R&P or t-case gear reduction?

I'm buildin' my zook up over the winter. I'm lookin' to spend as little as possible. i'm planning on running 33's. This vehicle WILL be a daily driver. With that in mind, would i be better off with changing my diff. gears, or t-case gears? If i understand it correctly... the 4.16 transfer case gears will preserve my low end torque, as well as increase my speeds on the highway. Am i understanding this correctly? I think i need some input.
thanx

Re: R&P or t-case gear reduction?

The R&P will help you all the time on and off road, the T-case will help some ON road, but will do alot more offroad.

I say go for T-case gears. You can drive a sammy fine with big tires and stock gears, I did it for 5 years I just didnt use 5th and I wasnt a speed demon but it still got me to 65, but the T-Case gears will give a better reduction for off road while helping some on road. :-)

Re: R&P or t-case gear reduction?

thanx DougO... another factor is complexity. I'm a do-it-yourself mechanic. I'm fairly skilled, but unexperienced. I usually have no problems with most jobs i undertake, but i haven't really tried anything for the highly skilled yet. Is re-gearing a t-case or a diff. better off left for the proffesionals? or would it be a good learning experience for me... i'm sure i'd be able to seek expertise from you guys if i got really stuck. i'd like to do it by myself, but don't want to mess things up!

Re: R&P or t-case gear reduction?

I would go for the 4:89 t-case gears[I think thats what the next set is]You will have a little bit better chance at using 5th gear,RR

Re: R&P or t-case gear reduction?

I've got the GRS 2 (4.89's) with 31's. I have no problems with 60 - 65 mph and love low range off road. It took me about 4 hours to do the gearset. That included pulling, cleaning, installing the gears and reinstalling the t-case. I'd never seen the inside of a Sami t-case or pulled one prior to that. I used regular hand tools. I did make a bracket out of 2" angle iron to hold the output shaft yo loosen the nut. Ring and Pinion, if you don't know what you're doing take it to someone who does. I bought mine from Petroworks and the instructions are great.

Re: R&P or t-case gear reduction?

you're turning 31's with no prob's eh?... i'm going with 33's though... but i guess one inch greater radius isn't that much difference eh?...
so you would also recommend the t-case gears over r&p for a daily driver?

Re: R&P or t-case gear reduction?

The Tcase gears would be less then a R&P swap, and I think easier to set up, less of a hassle also and can be done in a few hours providing ya access to the right tools, rather then a full day or 2 of setting up gears.

Re: R&P or t-case gear reduction?

What manufacturers make 4:89 gearsets for the t-case? Just petroworks?... it's kinda funny that i always see glenn and brent representing thier companys on this board, but never anyone from petroworks. It would be nice to be able to see every company representing themselves. the fact that i see these company's repsenting themselves and giving a hand to anyone who needs it kinda gives them some integrity in my eyes!

Re: R&P or t-case gear reduction?

I have a GRSII (4.89) case with 33 BFG's. I Have little probs. If I where you I'd look into the new 6.1 case from Asian auto parts of AZ. It lowers the high range lower than the 4.89 case
