JLP 4inch Shackles on 04 Lightning

Truckless
Hey John,

Just purchased and installed your JLP 4 inch shackles on my 04 lightning
on Friday. I have noticed that between 0-20 mph the ride is terrible, and I'm
feeling a ton of road vibration. The truck is basically new with 8k miles on it,
factory goodyear GSCs etc (of course your Air Box and Thunderpipe!)

I'm reading alot about pinion angle etc and wonder if this is my problem? I
didn't see any shims in your package as others are offering. I also wanted to
mention that these are at the max setting since I have an 04 with that huge
drop.

Please let me know how to fix this.. and give us an update on those turbo times too! LOL

Best Regards.
Chris
 
Update: Resolved the issue by reversing the lower shims 180 degrees on the bottom of each leaf spring. Thanks!
