I had the anti fade lock nut, Axcalibar axle, and the Lonestar twin row bearing carrier on my 1987 TRX250R and it was a bulletproof setup. I detonated the stock bearing carrier and it took out the stock axle too, so I replaced them both with Lonestar products. Then I ran into issues with the stock locknut backing off, which put my new Lonestar parts in jeopardy, so I bit the bullet and got the Lonestar anti fade lock nut and loved the way it performed. No more backing off, which restored my confidence in the reliability of my ride. After replacing the rear end components with Lonestar products, I never had to mess with it again. I got five years of intense riding out of it before I sold my quad to a friend. He's still riding it ten years later and still hasn't had any problems with the rear end.This part deserves a better star rating than it currently has. Lonestar makes far better products than all those Chinese knockoffs. Remember folks, more often than not, you get what you pay for, and if the deal looks too good to be true, it probably is.
