Use the KP bolt on 4-link, then make you some mounts for your coilovers. I make it sound easy eh? :lol: I would think you would just make your top and bottom shock mounts have several holes for adjustments, and I would think you would want them mounted as far apart as possible for stability.

I was going to use the KP, I looked at steve's friday and it is a sweet set up.

I was also looking at the CE upper and lower shock mounts, the lower has alot of adjustability. Just not sure on what spring rate and shock lenght. I still want to have about 7 inches of drop in the back.

I think you can get the Coil Over kit for the rear axle with the weld-on mounts from CE, can't you?

its a good idea to keep the length of the shocks at 7" instead of the normal 5". the longer travel will be a better idea because its a truck. im going with a 275lb rate spring.

Does CE have a website? I was going to go with a 4-link from suicidedoors.com because they build each 4-link to order. That seems easier than trying to adapt the kp 4-link that was made for bags.

The actual 4-link part of the KP is designed to use weld on bag mounts on the axle or the canti attachment out back that comes with bag mounts. The 4-link itself should be no different than any other to use with coil-overs or bags..customers choice. The biggest advantage is the KP is going to be a bolt-on application, while either bags or coil-overs would need to have brackets welded on the axle...so i guess its the same either way you go :D

It definately won't hurt or cause any problems running the KP with coilovers instead of bags though :D

i used a kp 4-link on mine. bought a coilover kit from chassisworks, which includes, upper mount with tabs, adjustable lower mounts. i have a bridge in mine. welded the cross bar on that. my coilovers are alden eagles with 300lbs springs. has a dampner adjustment and can adjust the bottom of the coilovers also. this is the setup i have found to work the best :head: i can gt some pics if you want also
here's chassisworks link .
here's a pic

I've been pondering the Idea of doing this. How does it ride?

Does the coil over setup eliminate wheel hop???

I was thinking of just adding helper bags or switching the coil overs. But coil overs are alot of work and $$$.

How much did the coil over setup run you minus the 4 link and notch??

How did you guys figure the springrate, shock height, and how much of a drop you would end up with? I want something with the equivalent of a 6" drop and would also like to use adjustable coilovers. Should I just contact one of the company's that makes coilovers or a competent drop shop?

then part # for the shocks i used is AS655 with a 300lbs spring. i used a 250lbs before and it was a little soft. the 300 lets me carry anything in the back if i want also. i can always ajust the rate also.
4-link $500.00
Alden Eagle coilovers- $400.00
brackets for mounting- about $150.00
i did all the other work myself.
i think the shacks are 14" eye to eye with a 10" spring
since this set up, i have not failed to hook up once and it has one hell of a launch :head:

Do you get wheel hop accelerating out of turns with the 22's on???

I get it like a mofo, but then again it's a 35 series tire under an empty truck bed.

yea.. bags really won't help the wheel hop and traction ussue that much..... they are simply made for adjustability and ride, although with the right setup, i guess it could work.

Coil over's are pretty much the best thing for performance suspensions :imo

Is most of the stability only because of the 4 link? Would bags also perform as well if not better?
Coilovers are designed with performance in mind(hence thier use on a lot of race cars). Air bags can be set up to perform well, with a good shock and the right PSI in the baggs. I'm a believer in coilovers for an allout performance vehicle. Now if you have the funds a set of front and rear coilovers for the track, and a set of ART Shockwaves for cruiseing and shows would be cool as hell.

Run as long of shock as possible. The formula for the spring rate is corner weight divided by suspension crush = spring rate. For an example, if the rear of your truck weighs 1500 pounds, it is safe to assume each corner weighs 750 pounds. If you run a shock with 6" of travel, and want ride height at half way thru it's travel ( giving 3" of up and down movement ), the equation would be 750 divided by 3 = 250 pound spring rate. Before you start taking the truck apart, go weigh it so you have a baseline to star with.
