RR20-145 Remanufactured Differential | Meritor Rear Rear Tandem Axle | 40K GAWR

📝 Product Description

Product Summary
The Meritor RR20-145 is a heavy-duty rear-rear tandem axle differential used in Class 8 trucks for line-haul and vocational applications. Positioned in the rear-most axle location, the RR20145 is driven by the power divider in the RD20-145 forward rear differential via the inter-axle driveline. It delivers torque directly to the rear drive wheels, offering robust performance and long-term reliability.

Each unit is professionally remanufactured in-house by DPE using a mix of high-quality OEM and aftermarket components. All differentials are thoroughly inspected to ensure correct gear mesh, proper backlash, and long-term service life.
