Fine Tune Corner Response with the XRAY 363353-H Rear Upright

Notable Build Features

• Material: High performance composite for consistent strength
• Roll Center Adjustment: Multiple selectable spots to refine body roll
• Toe Angle: 0 degree toe for predictable impact response
• Bearings: Larger outer 5x12mm and inner 5x10mm ball-bearings for a balance of durability and low weight
• Compatibility: Can be used on both the left and right side installations

Setup Advantages for Track Use

This hard upright provides a lower fixed roll center and three higher positions to tailor handling. The 0 degree toe specification helps preserve suspension geometry during hard contacts, while the larger outer bearings handle vertical loads and the smaller inner bearings help reduce rotating mass.
