Improve Stability with the XRAY 363353-H Hard Composite Upright

The XRAY 363353-H Composite Rear Upright is engineered to combine toughness with accurate suspension geometry for track days and club racing. Constructed from a high-grade composite, it performs well on medium- to high-traction surfaces where consistency matters.

Core Feature Summary

• Material: Tough composite material for extended service life
• Roll Center Adjustment: Several positions to alter roll characteristics
• Toe Angle: 0 degree toe for unchanged alignment after impacts
• Bearings: Outer 5x12mm for strength and inner 5x10mm for reduced mass
• Compatibility: Designed for use on both sides of the vehicle

Why Choose the Hard Upright

The part offers two roll center zones: a single lower fixed position and three selectable upper positions to tune turn-in and mid-corner balance. The 0 degree toe geometry keeps suspension behaviour stable in collisions, and the mix of bearing sizes helps manage load and inertia for crisper handling.
