This slide is made using 7075-t6 aircraft aluminum and polished. This slides range is from 30 to 50+ pinion gear and only works with the 3250 M2C RACING MOTOR MOUNT. FYI.

The largest pinion gear I could buy was a 45 tooth. You can use all (3) lock down screws with this slide. It will accept a larger gear, but you will only be able to use (2) of the 4 mm lock down screws as pictured above.

*THIS IS DESIGNED TO RUN ON M2C MOTOR MOUNT. WILL NOT WORK WITH STOCK MOTOR MOUNT *
