Just wondering if anyone has compared front vs rear and which seems to work better.

do it in the front or front and rear both,cant see how doing the back only would be beneficial at all.

IMO, how I set up:

Tire rotates one way. Spring pack rotates opposite direction. Leafs in rear separate, leafs in front compress.

Putting a clamp in the front will increase spring rate only. Putting one in the rear will reduce axle wrap under hard acceleration.

I say the rear. Casper will do 4 wheel burnouts and drift smoothly with no drama with 2 leafs, and a single clamp in the rear. I use the overload and the full leaf.

I was thinking rear based off the same ideas Pat stated, to limit wrap. I do wonder which would be better for traction, which is what I need desperatly. it seems to me limiting wrap would be better than any increase in spring rate.

who adds a leaf for drag racing?

I have always had good luck with front clamps only. However, I've never tried both or rear only.

i'm going to give the rear clamp a shot on friday. a quick street test gives me the idea it may work pretty well, it still spins but they dont just flat go up in smoke anymore. I also noticed it seems to squat the rear a fair bit under load.

I've had good luck with them just in the front, but I mainly got them for driving in sand. I was going to try the rear only too just haven't had a chance to swap them. Someone said he though his truck rode rougher with them in the rear.

It did make it ride a bit worse, I'll probably run them up to the center of the pack when I'm not racing.

I could swear I have heard complaints about ride from caltrac users too, and I don't think traction bars help ride either.

Spring clamps and traction or ladder bars will have a negative affect on ride quality. Bump stops are just ignorant to drive with

Yup, some are more livable than others. I haven't ridden in any trucks with catracs , but a coworker built a set of traction bars about 8 feet long that aren't very objectionable. His axle stops that are a touch too close to the axle can suck though.

Caltracs aren't bad to drive. Maybe if you run around with a lot of preload they're rough, but otherwise, they ride like stock.

I have a quarter turn of preload, and they ride rougher than stock, bumps (like bridge expansion joints) seem to hit a little harder. I think it is mostly from putting in the aluminum bushing versus the stock rubber bushing in the front spring eye. I have gotten used to it. :D
