We highly recommend that you replace your OEM RR4R or R4R chassis Trailing Arms with this better, stronger, much more superior Trailing Arm Kit. The OEM Trailing Arms on the RR4R & R4R Roadmaster® chassis diesel motorhomes (i.e. Knight, Cayman, Ambassador, Neptune, Simba, Cheetah, Zanzibar, Baron, Sahara & others) are known to crack and break, which can cause serious problems on the road.

We also recommend: REK-203 | Ride Enhancement Kit for the Roadmaster® RR4R & R4R Chassis. REK-203 is not a replacement, it is an enhancement to the Trailing Arms on these Roadmaster® chassis diesel motorhomes.


  • - This is an upgraded set of Trailing Arms to Replace the arms that come factory and are known to break. This comes in a complete kit with all of the hardware needed to install this upgraded replacement for the Roadmaster RR4R and R4R Chassis.

The Trailing Arm kit includes all new axle mounting hardware and has a powder-coat finish for ultimate corrosion resistance. These kits are built to address the original OEM parts installed at the factory and also supplied as replacement parts for field repairs. Our parts are many times stronger than the no-longer-available OEM parts, and our simple bolt-in design makes field replacement simple for any repair facility. Even if you have already had parts replaced due to failure, the parts used are the same design as the original and may fail. When the stock part fails, damage to shocks, air bags, driveshaft etc. are common and can be quite expensive to repair. Avoid the tow bill, added cost and weeks of delay in your travel plans, not to mention the risk associated with the loss of control of your vehicle while underway. Our trailing arms are shot-peened prior to powder coat and are covered by a limited life-time warranty.
