Installation Notes

Verify rear suspension configuration before ordering, especially on Mercedes-Benz E320, E430, E300, E420, and E55 AMG models. This shock uses an upper stem mount with M10 thread pitch and a lower loop bushing and sleeve mount, so confirm mounting style and sleeve dimensions against the original part. Replace only with the correct application-specific rear shock for vehicles without Sport Suspension where noted.
