Cherokee Front Springs

I decided to throw the dice and swapped my cut stock coils for a set of Cherokee springs. I am amazed by the difference in stored energy. I shouldn't be. The cherokee springs were 18.5 inches free length and squashed down to the perfect height. I used to be able to lift the bumper by hand an inch and now I can pull it up 5-6. I ran it last weekend with full exhaust, n/a and breathing all the hot air from under the hood and ran 13.1 @ 100 mph, the best i have ever done with out nitrous. I'm headed back to the track this weekend and am hoping for a shot of the front tires off the ground.

Re: Cherokee Front Springs

If you continue to use this spring and go faster, you will need a very good shock to control that spring. I am running in to that issue now and actually moving back to a shorter stiffer spring. My Rancho 9000's just can't keep the front end from coming up to fast.

I don't want to invest in the shock now as I would like to do a full mustang 2 conversion down the road. Spending $1k on shocks twice just does not make sense.

Re: Cherokee Front Springs

When the front end rises too fast does it unload the rear tires after the initial hit? Currently I am getting some wheelspin when I first launch and then they hook up

Re: Cherokee Front Springs

Take a close look at the videos I posted in this thread http://67-72chevytrucks.com/vboard/s...d.php?t=670129

This was last weekend. You can see it lifts both fronts. When it is coming down, it unloads the rear tire about 10-15' out. If I had a shock that could slow the rise, it would definitely help.

The options I have are 1) try to add more add more power, which might carry the wheelie further and still have the issue or 2) slow the rise.

What are you running for front shocks? I have a set of good QA1's that might fit your truck.

Re: Cherokee Front Springs

I have Rancho 9000's mounted in the stock 1963 location which is the back side of the control arm. I no longer have them mounted to the frame the way they were from the factory. I welded a couple ears that sit above the frame rail. I would be interested in them.

Re: Cherokee Front Springs

I used the 9-11" QA1 promastars on mine, with a similar setup and I'm pretty dang happy about the way it controls the front. If your tabs are higher, they may still work for you, but QA1 makes a step longer which are like 10.25-13 stroke which would make up the height difference if you needed to.

Re: Cherokee Front Springs

Thing is the Rancho does a fine job at 1.5ish 60's and slower. I have almost 8" of front suspension travel (shock sees roughly 4"). Combo works fine on motor, but on the bottle, it just had to much pretty foe l for the spring shock combo I have. I really need to go double adjustable with a real good shock.

Re: Cherokee Front Springs

Right now I have a set of Nitro drop shocks. Less than ideal. I'm going to see what happens this weekend with nitrous and if it's not good I might take you up on those 71Dragtruck

Re: Cherokee Front Springs

The nitros are usually VERY stiff on compression and don't control lift much. In generally they leave soft and land hard, not really ideal.

I picked up a pair out of an 03 grand Cherokee with the 4.0 I6. I hope they work.

Re: Cherokee Front Springs

Yes mine were from an early 90's Grand Cherokee as well. There were 2 options and I chose the heavy duty set. $118 Canadian for a new set. I think my suspension is working ok for now. Hooked hard enough on an unprepped track to hit my head on the back window!

I resent that, don't lump the LS guys in with the GenI SBC riff-raff.

Re: Cherokee Front Springs

Get the front end weighed and you will likely have your answer. But if I had to guess, I think it will be on the bump stops
