Positioned between the strut mount and spring pad, the bump stop provides crucial support for your vehicle's shock absorber. Its primary role is to prevent the strut from over-compressing when encountering significant bumps or rough terrain, which could otherwise lead to damage to the strut and other suspension components.

Constructed from a soft rubber material, bump stops are designed for maximum impact absorption. However, they are susceptible to dry-rotting and general wear over time. ECS recommends replacing bump stops whenever the spring strut is disassembled for maintenance or replacement.

Differential bushings are responsible for keeping the differential in solid alignment while dampening drivetrain vibration. While OE rubber bushings are fine when they are new from the factory, aged and worn out rubber bushings create a multitude of issues that can range from annoying to dangerous. As a factory bushing ages, it begins to harden and become brittle. When this happens the bushing will actually shrink and allow for movement at the differential mounting point. At this point, the differential is free to shift under load causing a noticeable clunking noise under acceleration and deceleration and massively increasing the stress on the driveshaft and axles. Manual transmissions suffer the worst from this as it can make shifting difficult since the differential will shift when the clutch is engaged and disengaged.

By replacing these bushings with full polyurethane, the movement is eliminated since the mounting point is supported by a much stiffer material that will not harden or shrink over time. This means less stress on the driveshaft and axles and greater longevity of supporting components.
