034Motorsport is pleased to present our new Billet Aluminum Rear Differential Mount Insert Upgrade for the B8 Audi A4/S4/RS4, A5/S5/RS5, Q5/SQ5 & C7 Audi A6/S6/RS6, A7/S7/RS7! The factory Audi rear differential mount has voids in the rubber damping medium, which results in excessive rear differential movement 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 both sides of the front-most factory B8 Audi A4/S4/RS4, A5/S5/RS5, Q5/SQ5 & C7 Audi A6/S6/RS6, A7/S7/RS7 rear differential mount, 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. These billet aluminum inserts are precision-machined to fill voids on both sides of the factory rear differential mount, and will not pack and wear out over time.

Features:
  • CNC-Machined Billet Aluminum Construction with Clear Anodized Finish
  • Application-Specific Design for Optimal Fitment and Performance
  • Engineered to Fill Voids In Both Sides of Factory Rear Differential Mount
  • 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!

Necessary for travel
Size: Medium (6.8"W*4.4"D*2.2"H), Color: Purple
This is really cute and looks classy. Quality is very nice. The only thing is the hooks for the necklaces didn’t keep them on, but everything else about this is a must for traveling and not losing or tangling up your jewelry.

LOVE IT!
Size: Large (8.2"W*4.2"D*2.4"H), Color: Beige
I love it. It’s very pretty and simple, in a good way. I plan to use it for all my jewelry and not just for travel. I like that it has a lot of hooks for necklaces and plenty of space for earring and rings. The fabric inside and out seem to be good quality. It’s well made and zips easily. The structure is sturdy as well. The color (white) is just as depicted. I think I got the larger size but it doesn’t feel bulky at all. I like that it comes with an extra pouch for bulkier items. It’s one of the best jewelry boxes I’ve had!

Nice little travel solution for jewelry
Size: Medium (6.8"W*4.4"D*2.2"H), Color: Pink
Cute travel box for my jewelry. The necklace hangers aren’t all that snug, causing my necklaces to fall and tangle some. But otherwise, works as expected.
