Product Description

PowerStop KOE15291DK is a Z17 OE Replacement rear drum and shoe kit designed for a broad range of 1983-1992 GM passenger cars, sport coupes, pickups, and SUVs equipped with the specified rear drum configuration. The kit combines two Evolution Premium coated brake drums with replacement semi-metallic shoes and the necessary drum-brake service hardware for a comprehensive two-wheel rear brake refresh.

The 241.3 mm drums feature a silver rust-preventative coating designed to resist corrosion, while the replacement shoes use 100% new steel construction with bonded friction material. Cam-ground and chamfered shoes are designed for precise drum contact and quieter operation. New springs, hold-down hardware, adjusters, and high-temperature ceramic lubricant help restore the mechanical operation of the rear drum assembly.

KOE15291DK covers selected Buick, Chevrolet, GMC, Oldsmobile, and Pontiac applications across multiple GM platforms, including RWD, 4WD, and AWD vehicles. Because these older GM platforms were offered with multiple brake configurations, verify the vehicle's rear drum size and factory rear brake type before installation. This kit does not include front brake components, backing plates, or wheel cylinders.
