Multi-position aluminium rear upright for lowered roll centre

The XRAY 323358 aluminium multi adjustable rear upright provides an additional lower suspension arm mounting location for the XB2 2026 platform, designed to change the rear roll behaviour for RC setups. That lowered arm point reduces the rear roll centre, which can improve traction feel and mid-corner composure on high-grip surfaces when matched with proper setup changes.

Constructed from CNC-machined aluminium, this upright keeps suspension geometry consistent and withstands frequent setup work. Two laser-engraved arrows help with quick side and orientation checks during servicing.

In tuning terms, choose the extra-lower position when the track has high traction and the car needs a firmer rear platform to limit squirm. Plan to adjust anti-roll bars, damper settings, and rear toe to rebalance handling after fitting.

How does the lower mount affect roll stiffness and suspension balance?

Lowering the rear roll centre reduces the lateral leverage on the rear suspension, which typically makes the rear feel more stable under load; you may need to soften the rear anti-roll bar or adjust shock compression to maintain balance.

When should I switch between standard and extra-lower positions?

Use the extra-lower position on high-traction layouts or when the car feels loose mid-corner; revert to the higher position for low-grip or bumpy tracks where preserving contact patch consistency is more important.

Do I need different shock settings with the lower upright position?

Yes. Because the roll centre shifts, expect to tweak shock valving and spring rates to keep weight transfer predictable; small incremental changes are recommended while testing lap times.
