XRAY 302181-H X4 Carbon-Fiber Fusion Front Lower Arm Hard Left - Carpet Spec  [XR-302181-H]

Front Suspension Upgrade for X4 Chassis

The XRAY 302181-H X4 CFF Carbon Fiber Fusion Front Lower Arm is a precision component built to sharpen handling on tight, high-traction layouts. This left-side arm uses XRAY's fusion of carbon fiber and composite materials to produce a lightweight yet durable suspension piece that helps maintain consistent geometry under load.

Built for Carpet and High-Grip Surfaces

Rated as a hard hardness arm, it is best suited to carpet and other high-grip surfaces. The thickness of the inner carbon fiber plate sets the arm stiffness and flex characteristics, while the surrounding composite balances rebound and durability. Together these materials give more predictable steering and quicker corner entry than stock M-style arms.

Lightweight Graphite and Composite Construction

Crafted from high-grade graphite and composite, the XRAY CFF arm stays compact and light to reduce unsprung mass. That compact profile helps racers tune handling without adding excess weight, and the harder layup gives repeatable behavior lap after lap.
