These lightweight spring arms are cut from billet 6061-T6 aluminum, and allow you to shed 12 pounds from the rear of your Model 3, while also enabling you the ability to run linear 70mm ID springs, allowing for easy spring changes for those who want to alter the spring rates of their suspension.

  • CNC’d from billet 6061-T6 aluminum, they look almost as good as they function.
  • Anodized for durability and aesthetics
  • Super light – 12lb weight savings vs OE arms and large rear springs (MPP comfort rear spring)
  • Retains OE aero panel – No loss to aerodynamic efficiency

No Springs - Supply your own rear springs (Please contact to verify compatibility).

Comfort Springs - Nearly equivalent to the springs sold with MountainPass Comfort Coilovers, and Sports coilovers with soft springs.


Sport Springs - Nearly equivalent to the springs sold with MountainPass Sports Coilovers (5% firmer).

NOTE: These arms will only work if you have a 70mm coilover upper spring perch already. If you’re using MPP Coilovers, they will work, and the only item required for installation will be rear springs.

Fits ALL Model 3 variants.
