Revolution Design B7 Aluminium Caster Block Pivot Balls

The Revolution Design B7 Aluminium Caster Block Pivot Balls (RDRP0702) are a smart lightweight upgrade for the Team Associated RC10B7 and B7D. These precision-machined pivot balls replace the standard steel versions and help reduce front-end weight significantly – each ball weighs just 0.21 g.

In addition to saving weight, the tighter manufacturing tolerances of the aluminium balls reduce play in the caster block and steering knuckle area. The result is improved steering precision, more direct response, and a smoother, more consistent feel on the track.

Features

• Replaces the stock steel pivot balls
• Made from high-strength aluminium
• Only 0.21 g per piece – significant weight reduction
• Reduced steering slop for better precision and feel
