who has tried them with success? do they last longer? no slippage or anything like that right?

his ideas sound rock solid, and its not much more for a rebuild kit and just buying it from ae.

The B-Fast diff rings, balls and thrust bearings make for a super smooth diff. They last longer and stay smoother longer than the stock pieces because the ball are riding on a perfectly flat ring. Diff slippage is all about how you have it adjusted. No rings/balls will last if you don't have it adjusted right. Just follow the directions in the kit and you'll have an ultra smooth long lasting diff.

The best materials and the best customer service in the industry go along way. I can run a BFast diff all season with minimal maintenance. I still have to clean the dust out of the thrust bearing, but it is smooth all season.

There are many that have tried them with great success. Most are weekend racers and some are pros. With a proper break-in and a clean and re-lube now and then they will last quite a while and stay smooth too. Take a look at the list of B-Fast team drivers, I can honestly say that none of the guys and gal would risk their reputation for some free $20 parts if they did not.

Some of the feedback we have received via email and on RcTech..
“Just came back from practice and all I can say is "WOW". the car would turn in on any car on the track. the diff. never "barked". the diff. setting is not as tight as what it was with the tq stock diff. I ran for over an hour and the diff. is as smooth as the day I put it in. B-fast all the way.” Reuben Diaz (TQ Racing)

“I just completed my buggy diff tonight and all I can say is WOW!!! In my 20 plus years of racing this is undeniably the best one I have ever built. The diff action does not tighten or free up at any point while turning. Your product is the best after market upgrade I've every used. Thanks again and I'll see you next weekend.” Eric Clark (Losi Team Driver”)


Me (Matt Chambers, Losi) and Dustin (Evans, Losi) are very happy to run and promote your products. We tell everyone we can how GOOD it is! We have a joke about the diffs... Dustin told me to feel his diff after a rebuild and I said "Do you have some bread?.... Cause that's butter!" haha


Hey Fred,it's Brian Kinwald...how's things?
I have been running the rings and balls for a few weeks now and really like them..
I would like to run for you if possible?....

Let me know what you think..
"Thank You"...BK
