This graphite front upper arm is manufactured for 1/10 formula racing and built to function as either the left or right upper suspension limb on YR-10F compatible chassis. Its one-piece construction aligns with typical front suspension mounting points to preserve steering geometry when replacing worn plastic components.
Fitting uses the usual hinge pin and ball-end configuration found on YR-10F designs, so original mounting bushings and fasteners can generally be retained. Routine hand tools for suspension service are all that is needed, and no chassis modifications are expected for correct fitment.
The stiffer graphite construction limits local deformation versus softer materials, which helps maintain camber under load and reduces progressive loss of steering precision. Fit this arm as a direct replacement to test improved longevity or to keep geometry stable through setup changes.
This listing includes 1 pcs, common for left and right sides, single replacement arm supplied.
