This is a great piece to help save expensive bearings. Piece seems to be well made. Only complaint I have is for the price I would think it could have at least came with the o-ring.

I don't have front wheel ABS anyways so this seemed like a no brainer. As with all riffraff products I've purchased this one is even nicer in your hand than it looks on their website. It's a shame these little guys get tucked away where no one will see them.

Nice to be able to grease the wheel bearings/unit bearings, when everyone claims they are "Not Serviceable"! How bout it only took about 10 minutes to remove the wheel, ABS sensor, connect this fitting, grease, remove fitting, and reassemble!!! Luv Riffraff Products!

Good idea and works great. Well made.

easy to use and did the job. definitely worth it.

Awesome product. Great design

Works great, approx 25 pumps to get grease throughout the bearings... Fantastic product...

I saw this while browsing Riffraff. After burning up a bearing, rotor & caliper a few years back I have always worried "when is the next bearing failure" Well not now, this little gizmo works perfect and a surprising amount of grease is allowed to enter. You will need to remove your caliper assembly and put it up onto your leaf spring nearby, then pull off your rotor to get to the sensor. I took apart my hub while I was there and greased up my needle bearings too. Nice product, highly recommended!

Was going to make my own gizmo, then heard about this. It makes the job a cinch. Perfect fit quality build, very happy customer. Just used it today, made the job literally 3 minutes! Highly recommend this.
