Tweak Corner Grip with the XRAY 363353-H Hard Rear Upright

The XRAY 363353-H Composite Rear Upright combines reinforced construction with predictable geometry to suit racers wanting consistency on medium- to high-traction surfaces. Molded from a high-tech composite, this upright focuses on strength and dependable track performance.

Durability and Adjustment Highlights

  • Material: Advanced composite chosen for impact resistance and long life
  • Roll Center Adjustment: Several selectable positions to dial handling
  • Toe Angle: 0 degree toe setting maintains stability under load
  • Bearings: Outer 5x12mm larger bearings for increased load capacity and inner 5x10mm to save unsprung weight
  • Compatibility: Symmetrical design fits both left and right hubs

Handling Traits and Setup Notes

The hard composite delivers two distinct roll center choices: a fixed low option plus three higher settings for tuning corner behavior. The 0 degree toe keeps suspension geometry reliable in heavy impacts, while the larger outer bearings support corner loads and the smaller inner bearings help preserve steering feel.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

What scale and cars will this upright fit?

This upright is aimed at 1/10 scale touring and on-road cars that use similar hub mounting layouts, especially for medium- to high-traction circuits.

Can I run different bearings in the inner or outer positions?

Yes, you can experiment with available bearing sizes, but the design expects outer 5x12mm and inner 5x10mm to balance load handling and rotational mass.

How should I choose roll center settings for a high grip track?

On high grip surfaces start with the lower roll center for stability, then try higher positions to increase rotation if needed. Small changes in toe and camber will also affect the final balance.
