034Motorsport is pleased to present Billet Aluminum Rear Differential Mount Inserts for the B9 Audi A4/S4 & Allroad!

The B9 Audi A4/S4 & Allroad uses rubber rear differential mounts which deflect under load, causing the rear end to feel vague and loose, as well as leading to less-than-optimal handling characteristics during on-throttle and off-throttle transitions. These precision-machined billet aluminum inserts are designed to fill voids in the factory rear differential mounts, and limit differential movement under load without sacrificing ride quality or introducing any perceivable additional noise, vibration, or harshness into the cabin. The result is a more refined, connected driving experience.

Designed to work in conjunction with the factory rubber mounts, this insert package was engineered using CAD software and thoroughly tested and refined to provide a significant improvement in handling performance and feel.

These inserts were tested extensively on 034Motorsport's in-house B9 Audi A4 Development Vehicle Installation is very simple and is completely reversible.

    My four approve
    Color: 3PC-Bacon-Brown, Pattern Name: Tough Dog Toys
    My dogs, which I have 4, 2 labradors, one Jack Russell and one medium smallish mixed breed dog, all really love the bones. Three of them seem to be vigorous chewers the mixed breed girl being the toughest one on bones. These bones are holding up really well and the dogs really seem to like them. The dogs have not been able to get any big chunks off of the bones so I feel safe letting them have them even when I’m not watching. I would recommend these to Pet owners.

    I have a medium sized dog and these were to big for him. A bigger dog would love them. Great for chewers.

    Great quality and flavor
    Color: 3PC-Bacon-Brown, Pattern Name: Tough Dog Toys
    I have two dogs that can chew through everything within a day. Not these, going on four days now, there are signs of wear and tear but still intact. The dogs love the flavor.

    Dog is Happy!
    Color: 3PC-Peanut Butter-Green, Pattern Name: Tough Dog Toys
    My dog likes the bones, especially because they are peanut butter-flavored. The bones are very strong and well-made, so they are good for heavy chewers. By the way, these bones are very large for big dogs only!
