Bearing a little stiff
Good aftermarket kit bellows and clamps are good. Gimbal bearing was very stiff and tough to install. Was tight on alpha gen 2 shaft.

Very impressive for the price.
The rubber was very pliable, the worm clamp did not strip. The rubber seems like it’s light I don’t know how long it will last but it is way easier to stretch in than OEM. The bearing is running smooth on but I only have 8 hours since installation.

Quality parts kit
I ordered this kit as well as 2 other $250 kits to compare them. I actually liked this kit much better than the expensive $250 kits. The rubber bellows were just as thick as the bellows in the expensive kit but were much more manageable to install because they were a little more pliable. The O-Rings and the rubber water hose ware the same quality. The gasket was a little thinner but we are talking only thousandths of an inch. No big deal really. The bellows clamps seemed to also be a little thinner but not inferior, just a little thinner. If you want a thicker gasket and thicker clamps you can order the Quicksilver gasket for $10.99 and go to your local auto parts store and and buy the thicker clamps for $8 and save yourself $155. You will thank yourself if you ever had to struggle installing the more expensive very hard non pliable Quicksilver bellows compared to the bellows in this kit.

Good value
I originally bought a “used” kit everything looked new except the bearing. When I tried to install it the retainer was damaged so I returned and got a new kit. Everything worked as expected.
