Put more power the the ground with our B9 Transmission Insert. This part quickly and easily installs and fills the voids in your factory transmission mount, helping to limit movement and transfer of energy. Effectively this stiffer mount will allow more of your engine's horsepower to make it to the wheels rather than being lost to wasted movement.WHY POLYURETHANE?
Polyurethane has always been used as a bushing material because it is able to absorb some energy, while still being stiff enough to limit movement- thus giving us the choice to dial in the optimal density for performance vs comfort. The reason many other companies choose to use full billet inserts stems mostly from the fact that they do not have the capability to offer polyurethane, and they would rather sell a part to you than not- regardless of the fact that it is not the optimal choice for material. Additionally the full billet metal inserts will be significantly more destructive to the existing rubber in your transmission mount which will rapidly deteriorate its integrity. Over time this will open up a larger gap and will induce extra play, ultimately making the full billet mounts ineffective. This is if the full billet inserts do not bend or snap first. Ultimately polyurethane has been, and will always be the best choice for this application.

Great vest for a great price!
This vest is more slim fitting, stylish, & flattering than many vests. It fits as expected, but it is adjustable in the back, so you do have some wiggle room to tighten & loosen it if you’re unsure about the size. My son wore this vest to homecoming. He is 5’ 10” & 150 lbs, & the size small was a good fit.

Great Quality Vest
Great quality vest versatile for all occasions. I personally felt it ran a bit tight (I ordered a large and felt like I was sucking in a bit the whole time) but I think an XL would have been too big. Overall impressed and happy with purchase.

BUTTONS LIKE A SMALLER SIZE. GOOD QUALITY.
DESIGN IS EXCELLENT. QUALITY IS FINE. I WEAR A LARGE, BUT THIS VEST, IN A LARGE, DID NOT ALLOW ME TO BUTTON ... AS IF IT IS A MEDIUM FIT. WILL RETURN, BUT IT IS A VERY GOOD VEST OTHERWISE.
