Overview
The Tuff Country 3 inch lift leaf spring (part number T/C19370) is a single rear leaf spring for Chevrolet and GMC trucks from 1973 to 1991. It covers K10, K20, K15, K25 and V-series pickups, Suburbans, Blazers and Jimmys, with a lift height range of 0 to 4.99 inches.
Tuff Country says its leaf springs are known for durability and ride quality. The springs are tapered, snub rolled, Teflon padded and pre-set, and each spring comes with polyurethane bushings.

Rear suspension on older GM trucks
Rear leaf springs on these trucks handle both the load and the drive forces, so the spring, shackles and axle mounts work as one system. A new spring with a higher arch changes the axle angle and can move the pinion relative to the driveshaft. Check the driveline angle and the U-bolt torque after the spring is installed, and look for signs of driveline vibration on the first drives.
Shackles and spring hangers wear in these trucks and can make a new spring feel loose. Replace worn shackle bushings at the same time, and inspect the spring eyes for cracks. Bump stops are worth a look as well, since a change in ride height changes how far the axle travels before the stop contacts.
