Product Details

Gates 90K-38108A is part of the Accessory Belt Drive Kit line, which is focused on restoring the full serpentine drive rather than replacing only the belt. That matters on higher-mileage vehicles because a worn tensioner or idler pulley can shorten belt life and create repeat front-end accessory drive problems. This kit is built for service on 1993-1995 Chevrolet and GMC models such as C1500, K1500, C2500, K2500, C3500, Yukon, Blazer, Tahoe, and Suburban variants listed in the fitment data.

This part cross-references Dayco D60968K1 and Litens LV999002C for the same application. The Gates 90K-38108A part number is also commonly referenced as the complete kit identifier for these fitments.

Common Problems This Kit Can Address

• Squealing or chirping from the serpentine belt drive
• Belt wear caused by a weak tensioner or worn idler pulley
• Accessory drive noise from the front of the engine
• Reduced belt tracking stability on aging drive systems
• Repeat belt replacement when related components are not serviced together

Installation Notes and Tips

Verify the vehicle’s engine accessory layout before ordering, especially on 1993-1995 Chevrolet C1500 and GMC K1500 applications with A.C., without A.P., and with a 120A alternator. Match the belt part number K060966, tensioner 38108, and idler pulley 38006 to the existing configuration before installation. Follow the included installation instructions and tech tips for accurate routing and component alignment.

For best results, inspect pulley surfaces, belt alignment, and accessory bracket condition during service. Replacing the belt, tensioner, and idler together helps restore the full serpentine drive system on compatible Chevrolet and GMC trucks and SUVs.

Gates designs this kit as an OE-equivalent accessory belt drive service package with application-specific components and installation guidance. The complete-kit approach is intended to support a thorough repair of the serpentine drive system on the listed vehicles.
