Jack-it has put together these 2 inch premium lift packages for the 73-87 GM ¾ 4wd. We start with the Pro Comp 2 inch front springs with u-bolts, Jack-it likes these springs because they are a 5 leaf spring pack with a 526LB spring rate. Springs include poly bushings, these bushings are the large side wall bushings. We use Skyjacker’s 2 inch rear leaf spring (52 inch)with the bonded OE style bushings, we also include a pair of rear shackles with bonded OE bushings and then front and rear Pro Comp ES3000 (Qty 4) shocks. Also the ES2000 steering stabilizer with your choice of shock boot color. Jack-it adds the front poly upper shackle bushings and a front spring and shackle eye bolt kit, Last is a set of poly front sway bars bushings.
There are a couple of options that you will want to check. The 1976 model year swapped from a Dana 44 front axle to a GM 10 bolt front axle, so we have the kits set up with the proper u-bolts for each axle. Most vehicles built June 76 and earlier have the Dana 44. The 73-87 GM ¾ trucks can have a 52 or 56 inch long rear springs, this 2 inch kit is only available for the 52 inch long springs. If you have the factory duel front shock set up you will need to order the two extra front shocks. Also want to check and see if your vehicle has the rear brake load valve 81-87 model years can have this option, if your vehicle does, you will want to order that rear extension bracket. Last there is an optional drop pitman that can be purchased also if you choose.
