Suspension Enhancement For a 2021 Newmar Baystar 3014 RV on a Ford F-53 V8 Engine 20,500LB Chassis

Question

Question:

I am interested in purchasing Roadmaster Sway bars for and sumo springs for my 2021 Newmar Baystar 3014. My question is do I need to install front and rear sway bars at the same time or can I do the rear later on? As far as the Sumo Springs. Do I need those ion I install sway bars? Thank you.

Currently it appears Roadmaster only offers rear sway bars for your 2021 Newmar Baystar 3014 class A RV motorhome. Your Baystar is on the 20,500lb GVWR Ford F-53 chassis. The 1-3/4" Roadmaster Rear Anti-Sway Bar # RM25VR is the stiffer option and the 1-5/8" Roadmaster Rear Anti-Sway Bar # RM-1139-149 is more price concious. I recommend using the stiffer 1-3/4" option since you have the full size slide out on the drivers side.

The SumoSprings Rebel Custom Helper Springs # SSF-173-40-2 are for the front suspension while the SumoSprings Maxim Custom Helper Springs # SSR-187-54-1 fit the rear suspension. You can install these with our without the sway bar in place. You are able to install these parts in any order you like. Personally I feel if you are installing the rear sway bar it makes the most sense to install the rear SumoSprings at the same time. This will make it easier since you will only have to raise the rear of the motorhome once to get under it.

Don't forget to look at the Roadmaster Exact Center Steering Stabilizer # RM63RR. This along with all the suspension upgrades you are making will greatly increase how easy your Newmar handles. It helps to reduce wandering and makes it easier to maintain steering straight ahead.

The torque spec for the rear U bolts on your 2019 F53 motorhome are dependent on the size. If you have 3/4 x 16 u bolts (and used a 1 1/8" socket to remove the nuts) then they torque to 250 lb-ft. If the u bolts are 7/8 x 14 (and you used a 1…
