What fits the GMC Sierra

The spotlight, the vehicle-specific bracket kit and the handle assembly. A Unity spotlight does not bolt on without the correct kit, so order them together.

Installing a spotlight on the GMC Sierra

Sierra and Silverado share a cab, so the kit lists match. The older C1500-C3500 and K1500-K3500 trucks take an H-shaft spotlight.

GMC Sierra spotlight questions

What is a shaft code and why does it matter?

The shaft is the tube that carries the lamp from the pillar to the handle inside the cab. Its length and bend are specific to the body - that is what the letter code (A, GM, V, H, CL, DC, P, PL, O) records. A GM-shaft spotlight will not sit correctly on a body that needs an H shaft, even with the right bracket.
