Give me some really good gear ratios for bashing with an HV-Maxx.... I want more speed then the 72t spur, 12 pinion that they reccomend for the system. Because it has way to much acceleration. I am running GP 3300's 6 cell with road tires from TRC, overall sweet truck, i want it to just go faster. Also, what would cause the front differential to turn hard?? I am somehow stripping out the hex's on the wheels and wrecking the idler gears also. DO you think steel Idler gears in the tranny is a safe bet with four CVD's as well?? or do steel idlers wreck the drive gears as well?????

Any ideas are welcome, THANKS!
