I ordered the kit from Norcal in July and finally got around to installing it last weekend. This truck kicked my ass during the process it took me 10hrs, new Ball joints, wheel bearings & alot of trimming of the plastic in the rear but it's finally complete!
It's the belltech 2/4 from Norcal with the belltech shocks and rear air bags
Ride height
Before
LF - 36.85
RF - 36.75
LR - 38.0
RR - 38.0
After
LF - 35.0
RF - 35.0
LR - 35.50
RR- 35.50
I will say It looks good, it's growing on me although a few of my friends are giving me a hard time about it being lowered saying instead of driving a SUV/Truck I now am driving a "fancy station wagon" lol I took all the measurements on the alignment rack and controlled / changed them as I felt necessary. The actual after results were lower but the ride quality was not what I wanted it to be for a DD, the rear bags were aired up and the front keys raised to get the ride height level and off the bump stops in the rear. The ride quality is pretty good but at times the rear seems a little bouncy but I haven't driven it alot probably 50 miles since lowering it so we will see if it improves as things go on.
Enjoy!
