BMW Rear Damper Jounce Bumper 31337847662 for F80 M3, F82 F83 M4, F87 M2 and M2 Competition

Restore precision and unlock extra compliance from the back end of your F8X chassis with this authentic BMW rear shock absorber bumpstop, part number 31337847662. This factory component adds about 25 mm of additional compression movement on F8X models and uses a firmer rate to better support the damper under load. The result is calmer body control, improved stability over uneven tarmac and greater confidence during fast-road and track-day driving, all while retaining true BMW quality and fit.

MJ Modifications has fitted this part on our own builds and for many customers, and feedback has been consistently excellent. Drivers report sharper responses, fewer harsh bottom-outs and a more composed rear axle when pushing on.

Key advantages

  • Genuine BMW part for perfect fitment and durability
  • Approx. 1 inch extra compression travel on F8X cars for better bump absorption
  • Firmer bumpstop rate for added support during hard cornering and braking
  • Ideal refresh for tired, perished or collapsed bumpstops
  • Subtle handling upgrade that pairs well with performance springs or coilovers

Vehicle applications

  • BMW F87 M2 including LCI and M2 Competition
  • BMW F80 M3 Saloon including LCI
  • BMW F82 M4 Coupe including LCI
  • BMW F83 M4 Convertible including LCI

Retrofit note: This bumpstop can also be used on F2X 1 Series and 2 Series, and F3X 3 Series and 4 Series platforms. When retrofitted to these models, it can reduce ride height by around 1 inch.
