Brand new genx spring rates?

[outofcontrol]

Will have to check on exact positions on shock settings they came straight from Keith burner at accufforce and bolted on car he had them preset for basic setup with the 500 on the car in burried the rf in the bump stop so I cut the top 2 steps off it and it was 3/4 of inch from hitting the bump with the 350 it was bottomed out like trying to smash threw the bump. J bar on the pinion plate which came from masters is below the pinion not sure on exact measurement I appreciate the help I'm stumped ran a smack car last year with all alluminum Chevy and it worked good but iv been told the gen x is a different feel but I understand no traction is no traction and zero movement is not somthing a bar car should do

The lower you go on the j-bar at the pinion, the more the call will want to roll. At or just below pinion might be a little high for what you have on the frame side. Try putting it about an inch below the pinion. That may help. But you should be getting some action where it is.
Call Keith and double check your shock settings. The Ohlins adjust in "clicks" and 0 clicks is turned all the way clockwise and that is full stiff. Then you count clicks counter-clockwise. Check your LR rebound. Depending on valving, you want that 25-40 clicks out. I'm wondering if you aren't way too stiff there. As viewed from below, turn that clockwise until it stops and see how many clicks it goes. If it is 15 or fewer, I think that's your problem.
Do you just run one shock on the LR? Or do you run a second shock on the front of the birdcage?

Matt can you re read what I wrote ??? I said
Some shocks going full soft to full stuff can move 10 pounds and some shocks can move 800 pounds. Im well aware that shock adjustments can make a huge difference but only if the shock is built in such a manner to allow a significant adjustment. I have seen a right rear that went from 86 to 92 lbs of rebound @ 3" from full soft to full stiff. And no I don't think many drivers would feel such an insignificant adjustment.

Sounds like the front end is moving. Where is the movement not happening? The car doesn't have to lift the front end to have traction.

the lr feels like its not coming up on bars the lift bar spring is a 325 and it showed about 6 inches of travel on 5th coil is that to much travel

Way too much.

[outofcontrol]

so what would you recomend going to stiffer spring could that be the reason the rear has no action

[hucktyson]

Are you measuring this travel at ride height or on jack stands ? I
Don't even think there's 6" available at ride height before the shock bottoms out. Do you have any preload on it ?

[outofcontrol]

At ride height sitting on the ground 2 turns of preload we put a additional 4 turns in it and made some practice laps it reduced travel down to around 4 inches and car starter to move a little but not a lot

[7uptruckracer]

Thats ALOT of travel maybe its trying to lift the front?

[rakracing]

I've always found with 7" of pinion angle anything over 4" of travel on the 5th shock levels the rear with drive shaft angle and breaks traction, i'd go back to the setup sheet and make shore all the setting are right, rear location, pinion angle,, and make shore the spring is a 325 and not a 225.

[Matt49]

Do you have your 5th coil way back by chance? The further back it is, the softer it "feels" to the rear end and that can make it travel more. This causes a lot of axle wrap up which raises the pinion side of the j-bar and can get you really loose.
Obviously we're all kind of making educated guesses at this point but this could be part of your problem. How far out is your 5th coil? For a 325 I wouldn't want it any closer than 33".

[outofcontrol]

It's at 36 inches
