MaxTrac 1-inch rear lowering shackles for 2011-2018 Chevrolet Silverado and GMC Sierra HD trucks. Fabricated steel with a gray powder-coated finish.

This is the smaller rear correction for a truck that only needs the factory rake trimmed back. The stock leaf springs stay in place, so the change is at the mounting point instead of the spring pack.

Fabricated steel. Gray powder coat. 1-inch rear drop. Pair of shackles included. Part 413710.
