This RC-scale graphite front upper arm is made for 1/10 formula use and designed to serve as the left or right upper suspension arm on compatible YR-10F chassis. The single-piece supply matches common layout for front suspension mounting points and keeps the steering geometry consistent when replacing worn or damaged plastic arms.
Installation follows the standard hinge pin and ball-end arrangement used on YR-10F layouts, allowing reuse of original hardware and mounting bushings. No special tools are required beyond routine suspension service tools, and the arm fits into the stock steering and suspension link geometry without modifying the chassis.
From a tuning perspective, a graphite arm like this reduces local flex compared with softer materials, which can sharpen steering response and stabilize camber behavior during weight transfer. Use it as a direct swap to test front-end stiffness changes or to maintain consistent geometry during setup changes.
This listing includes 1 pcs, common for left and right sides, single replacement arm supplied.
