XRAY 363313 Brass Rear Lower Suspension Holder Set - Precision Tuning Kit  [XR-363313]

Precision Brass Lower Holders for XB4

If you want finer control of your XRAY XB4 handling, the XRAY 363313 Brass Rear Lower Suspension Holder Set is a targeted upgrade. Machined from brass, the set adds weight low in the chassis to help increase traction and improve overall balance.

Quick Geometry Changes with I.S.S.

Built around XRAY's Integrated Suspension Settings (I.S.S.), these holders let you change suspension geometry rapidly. The I.S.S. concept has been scaled for 1/10 models to give accurate handling adjustments for both XB4 and XB4 2WD platforms using the +2mm holders.

Two Mounting Methods for Track Tuning

Choose the mounting that best matches grip levels and handling goals:

• With Composite Chassis Plate: Fitting to the rear lower composite plate raises the roll centre by +2mm, promoting more rotation through corners.
• Direct to Aluminum Chassis: For looser or lower-grip surfaces, attach directly to the aluminium chassis without the composite plate to help the tyres bite.
