Sure Grip unit feels much better than Eaton TruTrac did..

I bought a Powr Lok unit from him. He could have easily bit his tongue and got a bigger sale, but wasn't willing to.
I guess it was a bad batch. He said he had a bunch but wouldn't sell them until either Eaton or he made it right. That's called integrity in my book. Maybe the ones Moser got weren't affected, I really doubt they would sell anything they weren't sure of either, from what I have heard from people dealing with them. I just know Cass was very honest and helpful with me, and I appreciated it. I wasn't trying to give anybody sleepless nights worrying about something they bought. Cass didn't mention a design flaw with the Trutrac to me, only that he didn't like how the ones he had on hand came out on clearances. He does have an asterisk on his description that they require a thrust block, maybe that is the design flaw referred to? I don't know...
All I can say, is that if he wanted, he could have made more cash off me on the chunk and related parts, but instead I got a little free education.

I put him on the list of best Mopar vendors I have dealt with.
