Default Nitro Rustler Low End Torque Spur Gear

Hey guys, I have a Traxxas Nitro Rustler 2.5
I'm looking to increase its low end torque. I haven't done any performance upgrades but what I am looking to find is a spur gear that could give it quicker off the line performance. It comes with a 72t and a 70t optional - I currently have the 70t optional on it. Everywhere I look I see only 70t and 72t and I understand that is all traxxas sells for the nitro rustler. I was at the lhs last night and I found a spur for an t-maxx and it was a 64t - It looks identical to a rustlers spur -

T-Maxx spur: http://www.buytraxxas.com/product_in...roducts_id=741

Nitro Rustler Spur: http://www.buytraxxas.com/product_in...oducts_id=1267

If you guys know of any aftermarket companies that sell diff spur gear sizes or whether I can use a spur from a diff traxxas car let me know

Thanks alot

change your clutch bell. get a smaller tooth clutch bell and you will see a substancal increase in low end torque.

Default clutch bell

Traxxas only sells the 20t and 22t clutch bell - the 22t is stock

Will taking it from a 22t to 20t make a big difference?

Thanks

Yes it will make a big difference. I have a 18t clutch bell on my rustler. It took me quite awhile to find it but i found one.

I am running 18/72 and have a 16 clutch bell but haven't put it on yet. it will wheelie from a stop if the dirt is right with the 18/72.

Default wheelies...

will tightening the slipper clutch down help with pulling harder off the line or will losening it - also if I loosen or tighten will it hurt anything else?

Thanks
