About this part

1.5-Inch Rear Add-A-Leaf Pair, fitment-checked

Three conditions worth reading: Autoride models must use part C93AR, the factory shocks are retained, and OEM wheels and tires can be used with no more than 5 in. of lift. The add-a-leafs themselves give 1.5 in. and come with tie bolts.

Add-a-leafs work inside the existing rear pack rather than replacing it, and this pair gives 1.5 in. on the GM half-ton and three-quarter-ton trucks. The fitment record carries three useful notes: Autoride-equipped trucks are directed to part C93AR, the factory shocks are retained with this kit, and OEM wheels and tires remain usable up to 5 in. of lift. Coverage is the Silverado 1500 from 1999-2017 including the 2007 Classic and the Silverado 2500 from 1999-2004, in 4WD. Tie bolts included; sold as a pair.
