SPL Parts Solid Differential Mount Bushings for Select 2019-2026 BMW & Toyota Supra (SPL SDB G29)

Fits select 2019-2026 BMW 2 Series (G42), 3 Series (G20), 4 Series (G22/G23/G26), i4, Z4 (G29), and Toyota GR Supra (A90/A91).

SPL Parts Solid Differential Mount Bushings replace the compliant factory rubber bushings to eliminate differential movement within the subframe. Under hard launches and high-torque track driving, the stock bushings are prone to excessive deflection and eventual tearing. By securing the differential solidly, these bushings reduce wheel hop, improve power transfer to the pavement, and help protect the driveshaft and half shafts from shock loading and misalignment damage.

Since the factory bushings are not sold separately by the manufacturer, these solid replacements offer a cost-effective alternative to purchasing an entire new subframe. Each kit is precision CNC machined in the USA from 6061-T6 billet aluminum for a precise press-fit and long-term durability.
