shocks

i just did SOA on my 87 yj, i am lookin for 4" lift shocks, i am just wondering what a good shock is, i plan on doing moderate offroading and some onroad driving. i dont wanna spend a fortune but what a decent shock. i have been warned that ranchos are a very stiff shock, i want something that will be comfortable...
thanx for any help and advice

I have Rancho 5000s. I am spring over on slight lift springs and think my Jeep rides great. It rides much smoother than others I have ridden in running 4" lifts spring under.

If your going to order shocks anyway, you may want to be certain that "4" lift shocks" will provide you with enough travel. Spring overs usually net a little more lift than that and depending on what you did for lower shock mounts, you may need a shock that's a little longer or shorter.

Jack up each wheel of the Jeep and measure full compression and full extention length. If the parts store has a book they will be able to look them up using these measurements and having the correct ends for the YJ mounts or whatever you've changed them to.

Is this the only hammer you've got?

Actually, it's a little simpler than that.

With the jeep at rest...with maybe two adults sitting in it...measure the distance from shock bolt to shock bolt (top to bottom). This is your 'average' shock length.

Now measure the distance between the frame and bump stop. That is your minimum compressed length.

Now, using the shock chart that 'all' jeep guys keep handy, find a shock that has a compressed length equal to yours and an 'average' length equal to the max length - min length.

If you can't find one that fits, then it most likely means you have to have extended bump stops.

Don't have the chart? Spit me off your email address and I'll email you the Rancho chart.

When I did my SOA, by going to a shock that had 1" more than what I thought was my 'rest' space, I was able to use a shock that had 3" of additional travel....which is a good thing. Bump stops to follow......after I finish my front D44 Flat Top.

There are rancho shock guides out there... I can email you one tomorrow. You can usually find the RS9000x shocks on ebay for around $50 each. You can set them as stiff or soft as you like that way.

My vote goes to the Rancho 9000s too. I think the the 5000s are a little stiff.
