If you want strength, the live axle is NOT the way to go. I got bins or cracked and broken Live rails, they dont stand up to aggressive riding, jumping etc. When installed and set up by the right person they do work great, but they are super weak.
M-10 solid axle is the way to go, theres a few shops building them but the key is the set up of it. Its all in the way its mounted in the chassis, and adjusted from there.
People claim the CR and Racers edge M-10's are too much coin, what they forget is the hours, days and months of R&D that go into getting the perfect set up. I know first hand, late 06' I did the R&D for CR's 162, 2 tunnels, 5 diff external brackets, about 2 millions holes, diff shocks, springs, transfer blocks, rails and the list goes on and on. I counldnt even count the total hours. When buying a CR or Racers edge M-10, you get what you pay for !!!! Stop into Revy anytime and have a look at what skid's are taming the steepest chutes and hills. Prove is on the hillz......
And yup, it boon's awesome on the Nytro's.
