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

Much cheaper than OEM and just as good quality. Everything fit perfect, buy with confidence!

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.

I've never done one of these before. And that big one is a PAIN! You must get the tool to do it and even then, Holy money, did that suck! They say you have to lube both sides with adhesive and let them dry first...yeah don't do that, that is lunacy. Be faster than the glue's dry time which is about 30 seconds, and use the wet glue as a lube. Not easy! Very very tight!

On my 3rd season now and still no cracking visible.I did need to purchase a gimbal ring installer to get the gimbal ring retainer on the bellows.Was only $12.Without it you will have a hard time installing as the bellows rubber is a little thicker than oem...

Listen, I know your looking through review right now to see whether or not to purchase this product. Take this as your sign, regardless of the mostly positive reviews for this kit, nothing about this kit fits an alpha one gen 2. Bellows don't fit (important) as well as the seals. The only thing I was able to use from this kit was the gasket and I am weary of it's quality when compared to everything else in this kit. Buy OEM or Sierra and you will save yourself time and money.

Couldn't believe the price.Got the stuff and looked to be good.Only problem I had was the metric clamps. I'm geared towards the 5/16" hex heads on clamps and the ones provided were I think 7 mm. Made things a bit tense for me. I don't own a 7 mm swivel socket, but I eventually figured it all out.Pretty good product for the money!

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.
