The XRAY 323042-M Composite Rear Roll-Center Holder - Dirt Edition - Medium is designed to sharpen performance on loose dirt tracks. Crafted from medium-hardness composite, it balances toughness with accurate fit for repeated race use. Use it to keep the rear end steady when traction levels fluctuate.
Targeted at very-low to low-medium grip surfaces, this roll-center holder helps maintain a predictable ride when the surface gives up. The medium compound absorbs small impacts while keeping the suspension geometry consistent through corners.
The Dirt Edition provides a lightweight mounting solution that still resists wear, helping with throttle response and directional changes. It is a sensible upgrade for club racers and hobbyists wanting cleaner rear-end behaviour.
