Serpent 803187 Brake Pulley One-Way Set for 720 - Stability Upgrade  [SER803187]

Braking upgrade for Serpent 803187 on the 720 chassis

Fit the Serpent 803187 Brake Pulley Adaptor One-Way Set to your 720 to sharpen braking response and keep handling predictable under heavy deceleration. The kit is made to help drivers retain control when braking into tight corners.

Included parts and fit details

The Serpent 803187 set contains a new 2-speed shaft, a one-way adaptor, a pulley adaptor with an integrated one-way bearing, a replacement pulley, plus spacers and fasteners. These components let the front and rear wheels decouple on braking, helping the car stay balanced as rear tyres wear or load shifts.

How it improves cornering control

The centre pulley one-way bearing disengages when you lift off the throttle, letting wheels rotate independently so you can brake deeper into a turn without losing steering precision. That behaviour helps maintain stability and makes trail-braking more consistent lap after lap.
