Western Chassis is a company based out of Fresno, California that has been developing effective approaches to lowering a truck while maintaining proper ride quality since 1981.

Frustrated with the way "sport trucks" were having their springs heated and cut, resulting in harsh ride quality, Western Chassis designed and implemented some of the first drop spindles, first on the 1955-1957 Chevrolet Passenger Car and the Chevrolet C-10 Pickup (1970-1987) early on in their time as a company. This innovation allowed their customers to obtain the sleek look a lowered truck offered without any of the compromises in ride quality they were afraid of. Recently, Western Chassis has moved to a larger, more modernized facility that has allowed them to expand their product line.
