After a lengthy period of design and testing we are proud to announce the release of our complete replacement engine mount for Audi's 4.2L V8 found in the B6, B7, and some C5 models. This mount will completely replace your old, tired, hydraulic engine mount. In its factory form, the engine mount is fluid filled by Volkswagen/Audi to aid in creating a softer, cushier ride. This softness is a detriment to performance and overall longevity as the fluid within the mount can often cause premature failure. We eliminate this possibility by replacing the mount completely with our proprietary bushing and bracket/Cup design. Maximizing bushing area while trying to minimize vibration where possible gives our mount the advantage of having the best ride characteristics possible from a urethane bushing mount.

    Utilizing laser scanning technology - we are the first to offer a solution that gives a factory fit and finish to each mount. All bosses are matched replicas of the stock locations, and all tool clearances and specs are maintained.

    We are the first to develop a fully Billet Replacement mount for the Audi/VW Longitudinal platform that retains all of the factory alignment and stress relieving features. The use of billet aluminum instead of cast and an increase in minimum thickness creates a mount that is dramatically stronger than the cast stock mount.

    STAGE 1

    With its 65a durometer bushings are geared towards the spirited enthusiast who wants better control over motor movement without the sacrifice of excessive vibrations.

    STAGE 2    

    With its 85a durometer bushings are more for the hardcore enthusiast who is more concerned with performance than cabin vibration. Great for spirited runs and track cars. Not recommended for daily driven vehicles!

Very Disappointing
Color: Classic, Size: S 3.14 in (8 cm)
The ball is a hard plastic; not flexible at all and uncomfortable for my dog to pick up. It makes NO NOISE while rolling across the floor. I bought it for my newly blind dog because other dog owners said their blind dogs can track the squeaky noise and follow the ball. How... when it doesn't make the noise it's supposed to? It works only if I shake it, totally defeating the purpose. It would be difficult for my dog to chew on the hard plastic, so durability seems pretty good. It's also a nice looking toy, and I think it's safe, as there are no loose parts and the squeaker would be difficult to get to for most dogs. My dog WANTS to enjoy it, but she can't.

Picky dog approved!
Color: S6-muti-color, Color: S6-muti-color
I have wasted so much money on dog balls that they won't even pick up! They finally were obsessed with the Kong rubber green/blue or red/blue ones, but they're $3+. each, and they break from the dogs squishing it. I honestly had zero expectations on these, and they BOTH picked them up on the first throw! That's huge!! Seem to work fine in the ChuckIt. As for the squeaker, at first I was like "Oh nooooo." when they both loudly started! Much to my (and my neighbors') happiness, the squeakers stopped working after a couple minutes. 🤣
