From Exotek Racing:
High performance machined POM spur gears for all Exotek slipper eliminator hubs.
Our spur gears are 100% machined POM to insure true roundness, with extra interior machining to reduce overall weight for reduced rotating mass. Much stiffer and truer than molded nylon spur gears.
Requires 3- M3x6 button head screws (not included).
This size is best suited for stand up transmissions (spur may be too big for most laydown transmissions).
#1987 – 81T – $13.50 MSRP
#1988 – 84T – $13.50 MSRP
