Race-Ready Rear Lower Holder for NT1 Chassis

The XRAY 333713 Aluminum Rear Lower 1-piece Suspension Holder is a race-oriented upgrade that mounts rear bulkheads into the chassis to tune rear flex and improve handling on NT1 cars. Precision machining ensures repeatable fits and consistent setup changes.

Flexible Hinge Pin and Geometry Options

Square composite bushings, taken from T4 and XB4 designs, provide vertical offset and inner hinge pin width adjustment. These options let tuners modify roll centre and suspension geometry to suit track conditions and driving style.

Trim Profile to Enhance Traction

A narrower footprint allows closer arm positioning, yielding improved traction under acceleration and corner exit. The black finish is durable and complements a track-focused build.

Does this holder work with NT1 conversion kits?

It is designed for NT1 series layouts; compatibility with conversion kits depends on whether the kit retains the original bulkhead mounting points.

Are extra shims required for tuning?

Optional shims can be used to fine-tune vertical bushing position and inner pin width, providing incremental geometry changes without altering other components.

Will the black finish chip under impact?

While anodised black offers good wear resistance, heavy impacts can mark the surface; regular inspection after hard crashes is recommended.

Can this help with understeer on high grip tracks?

Adjusting roll centre and hinge width can change weight transfer and traction balance, which may reduce understeer when paired with appropriate shock and tyre setup.
