Fits 92-99 Suburban K1500/2500 4wd.

"Front units are identical between 1500 and 2500. Rears are dimensionally same, and have very little difference in valving so I have combined the two applications. There have been multiple configurations including 1500 series with 8 lug wheels, and 2500's with 6 and 8 lug wheels. Since a Suburban tends to be quite heavy in the rear, I find it best to use the slightly heavier duty shock." - JK

Note: Some vendors sell Ford and Dodge application shocks for these vehicles which I do not recommend. These are the D146/D147 units which are purpose built for the application. Thanks- JK
