Rear Suspension Holder to Improve XB4 Corner Balance

The XRAY 363321 Aluminum Rear Lower Suspension Holder is an upgrade aimed at improving cornering precision on high-traction tracks. Made for the XB4 range, it helps drivers refine rear-end behaviour with repeatable settings.

I.S.S. Geometry Adjustment Explained

This holder incorporates integrated suspension settings (I.S.S.) so adjustments to XB4 geometry are faster and more consistent. The idea, first used on the XB8, now benefits the 1/10 XB4 by allowing eccentric bushing and shim changes to alter roll centre and steering feel.

Specifications

  • Material: 7075 T6 Aluminum
  • Compatibility: XB4 & XB4 2WD
  • Adjustment Feature: Integrated Suspension Settings (I.S.S.)

Ideal for racers seeking a durable, tuneable rear suspension mount, this holder provides consistent geometry and robust construction for XB4 cars.
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.

Does this replace the stock plastic rear holder?

Yes, XRAY 363321 is an aluminium replacement intended to offer stiffer, more consistent mount points than the stock plastic part used on standard XB4 kits.

Will I notice a change in tyre wear?

With more precise geometry control you may see more consistent tyre wear over runs because suspension behaviour becomes more repeatable, though compound and track surface still drive overall wear.

Can I combine this with other XRAY suspension upgrades?

Yes, this holder works well alongside other XRAY suspension parts; pairing it with quality turnbuckles and tuned shock settings will help you extract the most from XB4 geometry changes.
