Gates 90K-38115A Serpentine Belt Drive Component Kit

Accessory Belt Drive Kit for Ford Trucks

Restore the front accessory drive on select Ford trucks with the Gates Accessory Belt Drive Kit 90K-38115A. This serpentine belt drive component kit is built around the belt, tensioner, and idler pulley needed to service the complete drive system on covered applications, helping address wear across the full belt path rather than replacing only one part.

Compatible with 1988-1992 Ford Bronco, F-150, F-200, F-250, and F-350 applications, including models with factory-installed air conditioning and enclosed spring design configurations. The Gates 90K-38115A kit is a direct-fit service solution for restoring proper belt tracking and accessory drive operation on these Ford platforms.

Product Details

The Gates Accessory Belt Drive Kit line is built to simplify full-system serpentine belt service. Instead of replacing only the belt, this kit addresses the belt drive as a system by pairing the belt with the tensioner and idler pulley specified for the application. That approach helps maintain proper belt tension and pulley alignment on vehicles where front accessory components have accumulated wear. Part number 90K-38115A is listed for select Ford Bronco, F-150, F-200, F-250, and F-350 models from 1988 through 1992, with notes for enclosed spring design and factory-installed A/C on applicable years.

This part cross-references Monroe Shocks & Struts (e.g., DBK060910A) for the same application.

Common Problems This Kit Can Address

• Squealing or chirping from a worn serpentine belt
• Loss of belt tension from a fatigued tensioner
• Belt tracking issues caused by a worn idler pulley
• Premature belt wear from aging front accessory drive components
• Repeat repairs when only the belt is replaced

Installation Notes and Tips

Verify engine configuration and accessory drive layout before ordering, especially on 1988-1992 Ford Bronco and Ford F-Series trucks with factory A/C or enclosed spring design notes. Compare the existing belt routing, tensioner style, and pulley part numbers to the kit contents before installation. Follow the included installation instructions and tech tips for accurate setup, and inspect adjacent pulleys and accessory brackets for wear while servicing the drive system.

Quality Assurance

Gates supplies this kit as an OE-equivalent service solution for the accessory belt drive system. The 90K-38115A kit is engineered to support complete serpentine drive restoration on the listed Ford applications using matched components specified for the vehicle platform.
