The GM 12-bolt pinion bearing spacer truck steel from DRP Performance is a precision-engineered component designed for serious truck builders and rear differential enthusiasts. This spacer plays a critical role in maintaining proper pinion bearing preload, which is essential for reliable differential operation under heavy loads, acceleration, and towing conditions.
Constructed from durable steel, this pinion bearing spacer maintains dimensional stability and resists deformation under extreme pressure cycles common in heavy-duty applications. The spacer functions by creating precise spacing between the pinion bearings, controlling bearing preload to keep bearings seated and eliminate slack while preventing excessive friction and heat generation.
This component is essential for anyone performing a complete 12-bolt differential rebuild or upgrading bearing components. Its compact footprint (3 x 2 x 5.5 inches) and lightweight design (0.7 lbs) make installation straightforward for experienced mechanics without adding unnecessary mass.
