Sorry integra i ment to say rear box (pinions and ringgears) i've never blown one but to many people have problems with these

I love my losi but i think all the driveline parts wear to quick.
pins, center CV couplers, Axles, Axle CV's, outdrives, Spurs, Clutchbells, Ring and Pinion gears. They all wear to quick. its the cheap sh!t taiwanesse steel that they are using in there cars. theres nothing that can be done about it.

Dont get me wrong i wouldnt trade my losi for anythng. but i've milled up new driveline parts out of higher quality steel to avoid replacing my entire driveline 3 times a year
