034Motorsport is pleased to present our new Billet Aluminum Rear Differential Carrier Mount Insert Upgrade for the B8 Audi A4/S4/RS4, A5/S5/RS5, Q5/SQ5 & C7 Audi A6/S6/RS6, A7/S7/RS7, as well as the D4 Audi A8/S8! The factory Audi rear differential carrier bushings have voids in the rubber damping medium, which results in excessive rear differential movement (twisting) under load. This movement allows for unwanted drivetrain slop (and sometimes clunks) that can be observed when accelerating, decelerating, and shifting.

These billet aluminum inserts are designed to fill the voids in the factory B8 Audi A4/S4/RS4, A5/S5/RS5, Q5/SQ5 & C7 Audi A6/S6/RS6, A7/S7/RS7 rear differential carrier mounts, and limit rear differential movement without sacrificing ride quality or introducing any additional noise, vibration, or harshness into the cabin. By filling the voids in the factory mounts, these inserts eliminate the associated slop and ensures that you're experiencing smoother shifting and throttle transitions, and an improved driving experience.

Installation is very simple, can be performed in minutes, and is completely reversible.

Features:
  • CNC-Machined Billet Aluminum Construction with Clear Anodized Finish
  • Application-Specific Design for Optimal Fitment and Performance
  • Engineered to Fill Voids In Factory Rear Differential Mounts
  • Drastically Reduces Rear Differential Movement During Shifting, Acceleration, and Deceleration
  • Improves Shifting Feel, Resulting in Crisper Shifts
  • Will Not Cause Additional NVH Transfer Inside Cabin
  • Easy, Straightforward Installation Takes Minutes!

  • 034Motorsport Billet Aluminum Rear Differential Carrier Mount Insert Pair

ITS SO FLUFFY
Color: White, Size: X-Large
This jacket is magical. For the price it’s pretty amazing. The only reason this isn’t a 5 star is the zipper is a little on the cheap feel side. Kinda loose feeling while zipping up. I’ve had no issues with it though. That’s being nitpicky. If you don’t have a weird feel for zippers it’s a 5 star review. Very lightweight and very comfortable and warm. I love the sleeve that goes past the cuff so if you are wearing gloves it helps shield them as well to stay warm. Great design and the fit is your regular fit. If you wear a large, get the large. If you want a little room underneath go one size higher. I did that because I like my winter jackets with a little bit of room. Great jacket would highly recommend
