K5 Blazer Rear Adjustable Spring Hanger Set (6 side bolts)
Our Price: $145.00

This is a pair of rear adjustable spring hangers. There is 6" of forward movement available, with holes every inch. This could allow up to a 12" longer rear spring to be bolted in while keeping the axle centerline in the stock location (for ex., swap from stock 52" springs to 64" springs - *note: you would have to either move your shackle hanger rearward by 6", or use one of our adjustable shackle flip kits as well to compensate for the additional 6" of length behind the axle). The holes are on a level plane with the vehicle, starting from the stock hole location going forward - creating greater ground clearance over moving your stock hanger forward and down for spring swaps. This is for K5 Blazers/Jimmy's only - truck bodies will have a gas tank in the way of mounting these!
*These are for Blazers/Jimmys with 6 mounting bolts on the side of the frame, and none on the bottom
GM Adjustable Zero-Lift Shackle Flip Kit
K5 ZeroLift Shackle Flip
List Price: $165.00
Our Price: $165.00

This is an adjustable Zero Lift* Shackle Flip Kit for 1977-1987(91) Chevy/GM Trucks/Blazers. This will allow for more shackle travel, and therefore greater articulation (given correct shock lengths, good bushings, etc...) Comes with welded nut strips for better load distribution and ease of installation. Gas tank removal highly recommended but not absolutely required for installation (tape a piece of heavy wire to the nut strip and slide it down the frame rail - it's difficult but it can be done!). Grinding/Drilling of factory rivets to remove existing shackle hangers is required. Bolts directly into existing rivet holes. Multiple shackle mounting locations for different length springs, and tailoring your shackle angle to your liking. Shackle holes are on a 1" spacing, and they are offset 1/4" so by swapping side-to-side you can adjust your upper shackle mounting location by 1/2" increments. Comes with mounting hardware. Can re-use your existing shackles, or we can supply you with shackles made-to-order at any length for an additional charge.
*this is approximately a zero lift shackle flip, but your actual ride height change will depend on shackle length, shackle angle, spring stiffness, bushing health, etc...
