Detailed Description

This Dorman lateral arm is designed for rear left upper rearward placement and uses bushing-to-bushing ends for a direct replacement layout. The arm measures 372 mm in length and uses a 12.2 mm mounting hole diameter. It is not adjustable, not greaseable, and does not include mounting hardware, so it is intended for straightforward suspension service where the original arm has worn, bent, or developed excess play. This part cross-references MOOG Chassis Products RK643627 for the same application. It also cross-references OE number 1663500106.
