[SCOTI]

How much lower do you want to go? The AirRide arms I've seen look like some quality pieces.... unfortunately, they don't make them for the 63-87 suspension yet. I've heard they're a month out for a couple of months now. When I spoke w/Darren @ AirRide, word is they still haven't started them. Knowing that, a month for fabrication to production is extremely optimistic.

For the front, I used 2.5" spindles w/1 coil cut from the factory 30yr old springs. This combo dropped my truck almost 6". With 215/75/15's up front on 15x6.5" van ralleys, I buzz the top of the inner-fenderwells on some dips (but only if going too fast). For normal roads it doesn't rub. I installed a 73-87 1 1/16 sway bar w/eurathane bushings & trimmed the factory bumpstops 1/2 ".

For the rear, if you want to get it low but still use it like a truck, go w/air bags. I used Firestone 224C's (approx 25-2600#) bolted directly to the trailing arms & added 1.5" lowering blocks from Classic Perf Products. This requires relocating the shocks for more travel & installing a c-section (I got mine from CPP). At normal ride height (30psi is my preference), my axle tube rides about an inch into the bottom of the framerail. When I hook up my car hauler, I air it up to about 60-70psi which returns the truck to unloaded ride height & adds an inch for extra travel. The c-sections allow more travel than the bed floor does in my case....the top of the pumpkin occasionally hits the bed floor (again usually only on dips @ too high of a speed).

I've used this truck daily for 3+ yrs w/o problems. Any lower & I would have to lose or raise the front inner wheelwells & cut out the bed floor.
