Weller Truck Parts remanufactured PACCAR Right Hand Stalks (RHS) are upgraded to eliminate the common connectivity issue within the OE assembly. Reman RHS are available for exchange on a limited basis due to core availability. Weller can reman and upgrade your existing RHS or upgrade a new service RHS before installation into your vehicle. Weller is always interested in purchasing rebuildable RHS cores, please contact a sales associate for core purchasing inquiries. Weller reman RHS assemblies commonly fix intermittent code 525 FMI 12, and sporadic transmission faults including failure to select gear and uncommanded neutral while underway.
