Only one problem, you have to fab a ring to fix the oem speedo gear.

i use it in my race car, best time was 11.02 @ 127.2 mph 1.66 60" with 24.5/8/13 at 7 psi.

 

We use it on Bryan Bridges Hot Rod Ek, 600+ torque 850+ hp and holding.

 

actually they have a stronger one for high hp drag cars compared to the one in the pic

 

I have been very impressed with the quality of the evolution products. I used another spool for a while and always had issues with the axles going in and out. The evolution one is as smooth as can be and holding strong.

 

Thank you! i will give it a try.
