Rocket stiff like a wagon in the back..outta things to check HELP
02 black front
Penske non adjustable non canister w/ coil over kits 4 races old
new Hyperco 12" 200 LR/225 RR
bird cages all free not bent no tight spots
rods are parallel to each other
all rods straight, right length & good joints
correct ride height
lift bar straight & level
lift bar locating rod straight, right length, good ends
5th coil good in farthest hole back
pinion angle @7 degrees
LR axle pulled
J bar good
drive shaft not bottomed out
nothing that moves in the back is making contact with anything else anywhere.
Every individual piece works as it should by itself but when all together its near rock solid when pressed down on...travel indicator show roughly 1/4" only when its bounced.
I have a little theory that may be way out in left field but...I am on 12" springs in the back. 200 LR 225 RR...Could it be entirely possible that in order to make ride height (8 1/8" axle tube to frame) that I am having to turn the adjusters down so far that it is causing coil bind?
Need ideas cause we're all out.
