Team Associated AS91891 HD Slipper Spring & Adapters - RC10B7.1 (91891)

The Team Associated 91891 HD Slipper Spring & Adapters set is a heavy-duty upgrade for the RC10B7.1 slipper clutch assembly.

Designed to handle higher power outputs and high-grip track conditions, this kit includes the upgraded slipper spring along with the necessary adapters for correct installation and consistent engagement.

Why upgrade to the HD slipper spring?

• Better handling of 6.5T-7.5T motors

• More consistent slipper engagement

• Reduced fade during long finals

• Improved durability under high grip

On carpet or high-bite astro, the standard slipper can start to feel inconsistent as heat builds. The HD spring setup helps maintain drive while still protecting the transmission and diff from shock loads.

Ideal as both a performance upgrade and a race-day spare.

Compatible with:

• RC10B7.1

A smart drivetrain upgrade for serious regional racing.
