Precision Rear Lower Holder to Sharpen XB4 Handling

The XRAY 363321 Aluminum Rear Lower Suspension Holder is aimed at drivers wanting crisper cornering on high-traction surfaces. Built for the XB4 family, this part helps refine handling and overall balance without major setup changes.

I.S.S. Fine Tuning for Track Setups

The integrated suspension settings (I.S.S.) in this XRAY holder let you make swift, repeatable tweaks to your XB4 geometry. First seen on the XB8, the I.S.S. concept has been adapted for the 1/10 XB4 so you can use eccentric bushings and extra shims to dial in roll and steering response.

Specifications

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

Suitable for racers wanting durable, consistent suspension geometry, this holder adds precision and toughness to XB4 setups for improved lap-to-lap performance.
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.

Will this bolt straight onto my XB4 chassis?

Yes, the XRAY 363321 is made for the XB4 and XB4 2WD layouts and installs using the standard rear suspension hardware for those kits.

How do eccentric bushings affect handling?

Eccentric bushings shift suspension pick-up points to change roll centre and anti-squat, letting you tune turn-in and mid-corner balance quickly.

Any maintenance tips for aluminum holders?

Keep mounting areas clean and check fastener torque after the first few runs; a light thread locker on steel screws helps prevent loosening without harming the alloy.
