Product Description

The Cusco 1C7 928 A Rear Differential Rigid Mount Collar is an aftermarket drivetrain upgrade part engineered for Toyota's high-performance AWD sport cars - specifically the GR Yaris and GR Corolla. By adding rigid aluminum collars around the front side of the rear differential mount, this component enhances the stability of the differential assembly and reduces unwanted movement during rapid acceleration or cornering. This helps improve traction feel and response from the drivetrain, especially under spirited driving conditions.

Designed as a bolt-on enhancement that uses your vehicle's existing differential rubber bushings, the 1C7 928 A installs in minutes with basic tools. Its billet aluminum construction offers strength and durability while adding a visual performance accent with its finished appearance. Ideal for owners seeking tighter drivetrain behavior and improved traction performance without replacing major components, this Cusco mount collar contributes to a more refined and confidence-inspiring driving experience on both street and track use.
