This RC-grade graphite front upper arm is produced for 1/10 formula applications and fits as either the left or right upper suspension arm on YR-10F compatible chassis. The single-piece design aligns with standard front suspension mounting points and helps keep steering geometry unchanged when swapping out degraded plastic arms.
Fitting follows the conventional hinge pin and ball-end layout used on YR-10F chassis, so original pins and ball studs are typically reused. No special installation tools are required beyond routine suspension service equipment, and the arm installs without chassis modification.
As a tuning component, graphite reduces local compliance compared with softer materials, leading to a firmer steering feel and more consistent camber under load. Fit this part to test front stiffness differences or to maintain geometry during setup adjustments.
This listing includes 1 pcs, common for left and right sides, single replacement arm supplied.
