Detailed Product Description

The Rein AVZ0303 jounce bumper is an application-specific suspension component crafted to replicate the exact shore hardness and design of the original equipment bump stops found on compatible BMW models. Constructed from high-quality rubber, this bump stop absorbs impact and limits suspension travel, protecting the shock absorbers and struts from damage. Its dimensions—2.5 inches in height and width, and 3.25 inches in length—are tailored to fit the suspension system precisely. The part is packaged individually and does not include installation hardware or instructions, so professional installation is recommended.

Common Suspension Issues Addressed by This Bump Stop

  • Prevents metal-to-metal contact during suspension compression
  • Reduces noise and vibration caused by worn or damaged bump stops
  • Protects shocks and struts from premature wear and damage
  • Maintains proper suspension travel and ride quality
  • Helps avoid suspension bottoming out on rough roads

Due to the specific fitment for BMW 3 Series models (323i, 325i, 328i, 330i, 335d, 335i, 335is), ensure compatibility before installation. Professional installation is advised to guarantee proper fit and function.
