Revolution Design 0717 - XRAY XB4 2025 - Aluminium Caster Block Set

Based on the proven RDRP design philosophy, these caster blocks are machined from aircraft-grade 7075-T6 aluminium to provide the perfect balance of reduced unsprung weight and maximum strength.

The 7° caster angle, used by most XRAY drivers, gives the car more initial steering. This makes the car more predictable and the overall steering response more stable. The black anodized finish with silver chamfered edges not only improves wear resistance but also gives the car a premium factory look.

Designed to replace the original composite parts, these aluminium caster blocks fit the latest XRAY XB4 2025 as well as all previous XB4 models.

Features:

• Precision-machined from aircraft-grade 7075-T6 aluminium
• Fixed 7° caster geometry for consistent steering response
• Lightweight design with high structural integrity
• Black anodized finish with silver chamfered edges
• Suitable for all XRAY XB4 models, including 2025
