This OEM Kawasaki rear suspension cushion lever, also called a shock linkage knuckle or relay arm, connects the frame, swingarm, and rear shock absorber. Made from cast aluminum alloy, it uses a three-point progressive design to transfer rear wheel movement smoothly into shock damping. The linkage supports inner collar needle bearings that help handle cornering force and vertical suspension load while keeping rear suspension movement stable. Replacing a damaged or loose relay arm helps restore proper suspension geometry, improve rear-end stability, and reduce unwanted play or wandering during riding.
