  • Roll Center Adjustment: Seven selectable positions for detailed roll center tuning
  • Toe Configuration: Set at 0° toe to help keep the rear stable under power
  • Secure Installation: Supplied with a set screw hole to lock the pivot pin in place

This rear upright is made to withstand the demands of club and regional racing, keeping the rear predictable through corners and stable on the straights. Use it when you want a firmer rear end and consistent traction response.
Remark :

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.

How hard is the part to install on an XB2?

Installation is straightforward for anyone familiar with XB2 rear suspension work. It swaps in using the same pivot pin layout and requires minimal adjustment to reattach the hub and shock geometry.

Will this upright change my car's handling on low-traction tracks?

Because the 323353-H is a hard composite upright, it will generally make the rear feel firmer and more responsive, which can reduce rear grip on very low-traction surfaces. Use the roll center settings to compensate for different track grip levels.

Do I need extra parts to secure the pivot pin?

No additional parts are usually necessary; the upright includes a set screw hole so you can secure the pivot pin using the factory style screw. Check thread condition before tightening.
