034 Motorsport - Rear Differential Carrier Mount Insert Kit, Audi B8 A4/S4/RS4, A5/S5/RS5, Q5/SQ5 & C7 Audi A6/S6/RS6, A7/S7/RS7 034-505-2016.

034 Motorsport is pleased to present our new Billet Aluminium 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 aluminium 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!

This stuff works!!
Scent: Fragrance-Free - Standard Size
This set has been the absolute best shampoo, lotion, and ointment for my little one going through a tough spell of baby acne. The ingredient list is clean, and worked miracles quickly. Baby’s skin was so soft, the redness disappeared within days. After just the second wash I could really notice a difference. Thank you Tubby Todd!

Perfect gentle routine for newborn skin
Scent: Lavender Rosemary - Standard Size, Scent: Lavender Rosemary - Standard Size
We started using the Tubby Todd 3-Step Baby Bath & Skincare set when our baby was just weeks old, and it has been amazing for delicate newborn skin. The Hair + Body Wash is extremely gentle and doesn’t irritate or dry out the skin. It rinses clean and has a very mild, pleasant scent. The Everyday Lotion keeps our baby’s skin soft and smooth without feeling heavy or sticky. It’s perfect for daily use after bath time. The All-Over Ointment is great for extra-dry areas, especially around the cheeks and legs. It creates a protective barrier that helps prevent dryness, especially in cooler weather. We appreciate that this brand avoids harsh chemicals and focuses on clean, baby-safe ingredients. This routine has become part of our nightly bath time and has kept our newborn’s skin healthy and moisturized. Would absolutely recommend this to new parents looking for a safe, gentle skincare routine for their baby.

It didn’t work for my baby
Scent: Fragrance-Free - Standard Size
Update on my review: gave it 5 stars because the customer service is great!!! Thank you uso much! I’m sorry this product didn’t work out for my little one. But thank you for having a great customer service! I’ve been using the products for about a week now and haven’t noticed any improvement in my baby’s skin. I do appreciate that the ingredients are clean, fragrance-free, and that the ointment is thick and suitable for eczema. However, I’ve seen other reviews mentioning results within a few days, and unfortunately, that hasn’t been my experience. For me, it wasn’t worth the money. At first I thought my baby had ringworm but I took him to his pediatrician and she said it’s a mild eczema, I don’t want to do steroid lotion, I purchased this hoping it would help and it hasn’t

Before and after baby newborn acne
Scent: Lavender Rosemary - Standard Size, Scent: Lavender Rosemary - Standard Size
As a first-time mom, I was really stressed when my newborn developed baby acne. The doctor told me it’s normal, but it was still hard to see. I tried other products like Nutella, but unfortunately, nothing seemed to help. Then I decided to try this product — both the face ointment and the body lotion — and I’m so glad I did. My baby actually loves it! Unlike other lotions, it doesn’t feel cold on her skin, so she no longer cries when I apply it. The biggest difference was how quickly it worked. Within just 2 days, her acne improved so much. I was honestly surprised and relieved. I definitely recommend this product to other parents. For reference, my baby is Asian, and it worked very well for her skin.
