RRP2331 Robinson Racing B5/B5M/DR10 Hardened Steel Idler Gear

The Robinson Racing Hardened Steel Idler Gear is compatible with the B5 and B5M buggies, as well as the T5M, SC5M and DR10 models. This is a direct replacement upgrade for any kit that uses the ASC91466 gear set. This part is precision machined from solid steel, then extra hardened for durability and dependability under the most extreme high power conditions. 

Note: The B5M 4-gear transmission uses two idler gears.
