When OE bushings eventually wear out, builders often struggle to find replacements as they are unavailable from GM. They can either buy an entire bellhousing to get the bushing, or settle for aftermarket bushings that don’t offer the durability they need.
Exclusively from Sonnax, this new, direct-replacement, OE-style bushing is impregnated with highly wear-resistant PTFE — not simply adhesive coated — providing unmatched durability. Its precision fit and function assure a long bushing life, and it’s readily available for your next build.
The OE pump bushing in GM 6L50, 6L80 and 6L90 units utilizes a PTFE-impregnated load bearing surface to support large forces and survive dry-start conditions. Replacement bushings are unavailable from GM, so when this bushing eventually wears out, builders have the choice of buying an entire bellhousing to get the bushing or settling for aftermarket bushings that can’t stand up in this environment. Unfortunately, it is also very common for these units to suffer internal torque converter failures which create debris that ruins this bushing.
