Rear Anti-Roll Bar

Steel torsion bar that connects the left and right rear suspension to reduce body roll during cornering. The rear anti-roll bar (ARB) is adjustable to tune handling balance—stiffer rear bar reduces oversteer, softer increases rotation.

The ARB mounts to the chassis and connects to the rear suspension via rear alignment uprights and push rods. ARB stop washers maintain proper clearances and prevent binding. The bar's stiffness affects how much the rear suspension resists roll, which directly impacts cornering behavior.

This is an OEM replacement part that comes standard with the Rush SR. Sold as a complete assembly. If you're experiencing excessive oversteer or understeer, adjusting the rear ARB stiffness is one way to tune the handling balance.
