This is a pair of GM Blazer/Jimmy 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!
*This version is for Blazers/Jimmys with 8 total mounting bolts per bracket (4 on the side of the frame and 4 on the bottom of the frame)
This item is "Make to Order", and can take anywhere from 2-5 days to fabricate before shipping!
