Description
The GMC 3500 pickup truck spindle is designed to provide stability, even weight distribution, and improved steering performance for heavy-duty applications. Crafted from high-strength 1040 steel, this spindle is built to withstand the demands of towing, hauling, and commercial use. Its precision-machined bearing surface ensures a secure fit with OEM wheel bearings and hubs, reducing wear on suspension components and extending their lifespan.
For older GMC 3500 models equipped with the GM 10.5-inch Full-Float Rear Axle (pre-1980), a four-piece double nut and double washer system was used for wheel bearing adjustment. In 1980, GMC introduced a more durable single spindle nut design with a solid key and retainer ring. This replacement spindle is compatible with both setups, ensuring a versatile fit for both axle configurations.
