Just tring to figure out if i should do the slipper clutch upgrade for my 2.5 maxx tranny i still have the stock slipper clutch setup with the friction pegs. With the upgrade i can use the 3.3 maxx size spur gears right? the 56 and 58 and what not. is there a power increase wll torque and speed increase? i would imagine there would be but havent heard much about it. Any input would be great. I already have the 3.3 installed on the truck just tring to get alittle bit more speed outta her with a 64 tooth spur on it now its pushing high 40s low 50s and i got the weight down to 7.2 lbs without fuel and lid so its pretty light.

<p class="MsoNormal" style="MARGIN: 0in 0in 0pt"><font face="Times New Roman" size="3">The Revo spec slipper upgrade is a good one, but… The upgrade uses a cupped 72T spur gear. The reason for the spur being cupped is the new style slipper is thicker than the friction type slipper. They had to cup the spur to get the CB and SG to line up properly since the slipper would sit closer to the clutch bell if the didn’t. </font></p><p class="MsoNormal" style="MARGIN: 0in 0in 0pt"><font face="Times New Roman" size="3">The New Maxx and Revo spurs do fit the slipper but do not line up with the CB correctly; they will be offset closer to the engine by approx 3mm. which causes the SG and CB to overlap. </font></p><p class="MsoNormal" style="MARGIN: 0in 0in 0pt"><font face="Times New Roman" size="3">You can slot the chassis plate engine mounting holes and use larger washers to overcome the issue or take a chance with stripped spurs.</font></p><p class="MsoNormal" style="MARGIN: 0in 0in 0pt">

wow that kinda sucks so basically with anything other than the 72t gear thats part of the kit ill have to move the engine back and towards where the fuel tank use to be. now will a 3.3 transmission or a 2.5R tranny work? the regular black tranny is good but i want to run smaller spur gear and the smallest ive found for the black tranny is the kimbrough 64T

theres a kit called torque control slipper upgrade kit. it takes the slipper system from the 3.3 tmaxx, and it uses the same exact size spur gear that the 2.5 uses. i just put one on my tmaxx and it looks fine, i just havent ran it yet. but you can get it atyour LHSand it costs between 20 and 30. so instead of making engine mount adapters and other stuff like that, you can just slap that kit on it and run it. it has complete instructuions to install.

I think he made the plate so he could use revo spurs, for high speeds.
