Kenworth Window Regulator R21-1002R HLK2470

The R21-1002R is a manual window regulator for the right-hand (passenger) side of various Kenworth truck models. It is primarily designed for older or specific configuration Kenworth cabs that utilize a manual crank handle rather than an electric motor. 

Key Specifications

Part Number: R21-1002R.

Position: Right-Hand (RH) / Passenger Side.

Operation: Manual (Crank-driven).

Length: Approximately 17.937 inches.

Left-Hand Counterpart: The driver-side equivalent is R21-1002. 

Vehicle Compatibility

This regulator fits various Kenworth heavy-duty models. While often used in similar models to the R21-1004R series (such as the T600, T800, and W900), it is a distinct assembly. You should verify your specific OEM number or door configuration before purchasing, as internal door mounts can vary.

Quality and Testing

TinzerMotor produces these window regulators and window motors with a focus on long-term high quality and mechanical reliability:

Heavy-Duty Construction: Uses thickened steel plate components and reinforced pivot points to prevent the "sagging" or jamming common in lower-quality aftermarket parts.

Extensive Testing: Each unit undergoes rigorous cycle testing, involving thousands of manual rotations under simulated glass weight to ensure the internal gears do not strip or slip over time.

Precision Fit: Designed to align perfectly with the original door mounting holes, ensuring a "bolt-on" installation without the need for drilling or modification.
