Overview

These polyurethane bushings prevent the differential from moving around, enhancing the car's ability to transmit torque to the rear wheels and improving throttle-pedal feel. They are available in different hardness options to suit various build types, from street-focused performance to track or drift applications.
Show original supplier description
By eliminating differential movement, these polyurethane bushings significantly improve torque transfer to the wheels, enhancing overall performance and throttle response. Whether you're building for canyon roads, drifting, or racing, AKG offers options to suit your needs. These bushings are crafted from an exclusive U.S. Mil-Spec polyurethane compound, available in 95A (medium-hard) for performance and drift builds, or 75D (hard) for race cars and high-horsepower applications. The 75D compound provides performance comparable to metal bushings without the harshness on the chassis, while also resisting deformation common in plastic bushings. They are manufactured in the USA under ISO 9001:2015 certified standards, with precision molding and CNC finishing for a perfect fit. The product includes 6061-T6 aircraft-grade aluminum sleeves and comes with a lifetime replacement warranty. These bushings are specifically designed for the BMW F30 (2012-2019) 320, 328, 330, 335, 340 (excluding M3), F32 (2013-2019) 420, 428, 430, 435, 440 (excluding M4), and F22 (2014-2020) 228, 230, 235, 240 (excluding M2) models. They replace BMW part numbers 33316792513 and 33316880637. Note that the material used for the differential bushings must be compatible with the material used for the subframe bushings.
