Kyosho UMW742B Rear Suspension Arms Carbon Composite for RB7  [KY-UMW742B]

Performance Rear Arms by Kyosho UMW742B

The Kyosho UMW742B Carbon Composite Rear Suspension Arm Set upgrades the RB7 chassis with stiffer, lighter components suited to fast club and regional racing. The carbon composite construction focuses on keeping the arms resilient while trimming unnecessary mass.

Advantages of Using Carbon Composite Arms

Carbon composite delivers notable stiffness with less weight compared to conventional materials. Fitting the UMW742B reduces unsprung weight on the RB7, helping tyres track surface contours more effectively and improving steering precision.

Engineered for RB7 Compatibility

These arms are produced to align with RB7 points and geometry for a direct swap. That means you can upgrade quickly without altering mounting locations or basic suspension setup.

Built for Aggressive Driving Styles

Drivers who push hard will appreciate the UMW742B's combination of toughness and precise feel. The design supports more consistent suspension behavior during fast direction changes and throttle application.
