XRAY 333713 Rear Lower Suspension Holder Aluminum Black  [XR-333713]

Precision Rear Suspension Upgrade for NT1 Cars

The XRAY 333713 Aluminum Rear Lower 1-piece Suspension Holder is a precision-machined upgrade that improves the rear end behaviour of NT1 series vehicles. Built to secure rear bulkheads directly to the chassis, it fine-tunes rear suspension flex and boosts stability under load.

Refined Geometry and Adjustment Options

This holder uses square composite bushings adapted from T4 and XB4 parts to allow vertical positioning and inner hinge pin width adjustments. These settings broaden roll centre and geometry tuning so drivers can dial in cornering balance and responsiveness.

Closer Arm Mounts for Better Traction

The compact profile enables the suspension arms to sit nearer to the chassis, helping increase traction on tighter tracks and high-grip surfaces. The black anodised finish gives long-lasting wear resistance while keeping weight minimal.
