Front Spring Bushings for '67-87 GM Trucks

Includes bushings/sleeves/bolt/lock nut for both ends of both springs.

Note: These kits use a 1/2" bolt at the back of the front spring, the factory bolt size is 7/16".  If you have our HD shackles, they'll already be drilled to the correct size.  If you're re-using your stock shackles, they'll need to be drilled out to 1/2" for the larger bolt.  We opted for the larger bolt because the stock 7/16" bolts are failure prone and it's easy to drill the shackle.

'88-91 GM square body trucks use a 9/16" bolt at the back of the front spring, call us for kits on that application.
