Probably not, but you won't loose as much speed on hills.

To get more speed with a series cart, you need to increase battery pack voltage or change the final drive ratio, or both.

Taller tires effectively changes the final drive ratio, so going to a 22" tire would give you about 3-3.5 MPH more.

I'm not sure about a Marathon, but a TXT is 12.44:1. From what I can tell, most guys go to bigger tires first.

I'm not into building carts, so I can't help with what is available or where to get it, but maybe some knowledge people will chime in.

Check out the Site Sponsors, give them a call or e-mail.

Most likely, you'd be on the phone to Scotty, ordering a bigger controller and heavier cables.

Seriously, have you up-graded the F/R switch and Solenoid. If not, you need to.

Also, going from 12.44:1 to 8:1 will up the speed by about 37%, but will reduce torque by a similar amount and a 400A controller and 4Ga cables might be a little on the puny side.

Good luck, have fun and be safe.......
