(33531136395) - Rear Bump Stop - 318i/323i/325i/328i (92-99), 323i/325i/328i/330i (99-06) (Lemforder/Germany) (2 available)

BMW part number 33531136395 is a high-density polyurethane foam rear suspension bump stop (officially referred to by BMW as an additional shock absorber or jounce bumper). Its primary function is to serve as a cushion that prevents the rear shocks from bottoming out during heavy compression or when carrying extra cargo, shielding your rear shock absorbers and chassis from harsh physical damage.  These are NOT for use with Bilsteins or Factory Sport Suspensions: This part will not fit models equipped with factory M-Sport suspension, lowered performance suspension packages, or full M3 models. Sport models require a shorter bump stop to accommodate the reduced travel height. (27c)
