XRAY 363313 Brass Rear Lower Suspension Holder Set - Heavy Duty Tuning Option  [XR-363313]

Tune Your XB4 with XRAY 363313 Brass Holders

For racers looking to dial in their XRAY XB4 machines, the XRAY 363313 Brass Rear Lower Suspension Holder Set is a practical performance upgrade. Manufactured from solid brass, it places weight low in the chassis to boost traction and lower the center of gravity for competitive handling.

Integrated Suspension Settings for Fast Adjustments

The holders feature XRAY's Integrated Suspension Settings (I.S.S.), enabling quick changes to suspension geometry on the fly. Adapted from larger platforms, the I.S.S. gives precise control for 1/10 scale XB4 and XB4 2WD cars, and the +2mm holders fit both variants.

Fitment Options to Match Track Grip

Two mounting approaches let you tune roll centre and traction for different surfaces:

• With Composite Chassis Plate: Mounting on the rear lower composite chassis plate raises the roll center by +2mm, increasing cornering rotation.
• Direct to Aluminum Chassis: For low-traction tracks, mount directly to the aluminum chassis without the composite plate to gain grip and stability.
