Description

The USA Standard Gear NP435 Bearing Kit is a comprehensive overhaul solution for your vehicle's manual transmission. This kit is specifically engineered for 1965-1986 NP435 4-speed transmissions equipped with synchronizers, ensuring a precise fit and reliable performance. This kit includes essential components for a complete rebuild, such as synchronizer rings, a ball-style rear mainshaft bearing, and a tapered input bearing. The transmission features a robust 10.75-inch long cast iron main case and an 8-bolt aluminum top cover, contributing to its durability. Additionally, the design incorporates a PTO cover located on the right side of the case and centered from front to back. The USA Standard Gear NP435 Bearing Kit is compatible with a wide range of Ford and some Chevrolet/GMC vehicles from 1965 through 1986, as well as select 1987 Ford models. The extensive fitment list includes various Ford Bronco, E-350 Econoline, F-100, F-150, F-250, F-350, F-500, M-400, and P-350 models, along with Chevrolet Blazer, C10/C20 Suburban, and K10/K20 Suburban, and GMC C/K series trucks and Jimmy models within the specified years.
