Hey Paul, thanks for the information! To add sway bars to your 2025 Entegra Oddessey, I recommend the following parts:

Front Sway Bar - Roadmaster Anti-Sway Bar item # RM-1139-189. This kit includes a 1-3/8" diameter sway bar, polyurethane bushings, and reinforced end links.

Rear Sway Bar - Roadmaster Rear Anti-Sway Bar item # RM-1139-147. This kit includes a 1-1/2" diameter sway bar that is going to be a noticeable upgrade if your motorhome came with the factory option. It also includes all new mounting hardware along with polyurethane bushings, and stronger end links.

These sway bars and end links are constructed of high strength steel. They're going to last longer than any factory options or components. The front sway bar is going to help with your front end tracking and the side to side swaying. The rear one is going to help with that top heavy body roll feeling.

I also recommend adding the Safe-T-Plus Steering Stabilizer with Mounting Hardware Kit item # ST98MR. If your forearms have ever been sore after a long trip then you'll definitely want to make this upgrade. The stabilizer is going to keep your wheel centered and prevent oversteering. This kit includes custom mounting brackets.

What kind of issues are you running into when you're on the road that has you wanting to add sway bars?

I have already installed Safe T plus which made a big improvement. The problem I still have is wind gust and passing trucks. It feels like I’m hanging on for dear life. You can feel the whole vehicle role side to side. Reading a lot of forums and reviews, it seems this is a common complaint with different models with the Entegra line. The most common solutions people are doing is the Safe T plus, anti sway bars, track bar, changing to a better shock. Several people have suggested getting it aligned with different settings and also moving the helper springs closer. I’m trying to make the biggest changes one at a time. A lot of money to spend, specially when you buy something new and have to make these changes just to feel safe driving it. Your advice will be very much appreciated. Paul

@PaulS I installed these on my Nexus Triumph 32T that had a 6 inch lift kit installed and it made a world of difference. I did have to change out the sway bar links for a longer F350 style because of the lift kit. Had the lift kit not been installed the sway bar links that came with this kit would have worked out properly. I recommend this product.

@PaulS I installed all parts you mentioned on my jayco class c e450, (including koni shocks). Couldn’t be happier. Vehicle tracks straight down the road. No drifting, buffeting or getting pushed around. Expensive, but takes white knuckling out, and makes for pleasant, confident driving. I did all work myself. Make sure to have front ends aligned after all work completed. Use the +5 degrees as recommended in forums. I provided the shop with moog adjustables. Hope this helps. Barry b

@PaulS You're welcome! The sway bars are definitely going to help to address that top heavy side to side feeling. You absolutely need to get an alignment after installing the Safe-T-Plus Steering Stabilizer item # ST98MR.

Hi Jerred, Would these same part numbers apply to a 2026 Jayco 30z? Same E450 chassis. The website says it wont fit and put me in the "E450 cutaway" category. Just wanted to verify before I order them as the Entegra Oddessey and the Jayco and exact same chassis and I don't think anything changed between 25 and 26? Thanks!!

@StevenS They sure will! The Front - Roadmaster Anti-Sway Bar item # RM-1139-189 and Rear - Roadmaster Rear Anti-Sway Bar item # RM-1139-147 are both going to fit the 2024 and 2025 Ford E-450 Class C Chassis along with the Safe-T-Plus Steering Stabilizer with Mounting Hardware Kit item # ST98MR. Your 2026 Jayco 30z motorhome was built on either a 2024 or 2025 Ford E-450 chassis. The chassis on the motorhomes are typically a year or two behind.

Hey Mark! If you’re replacing an older stand-alone 45-amp converter like the Iota DLS-45, the direct WFCO equivalent would be the #WF58FR WF-9845-AD-CB, 45A. If your battery setup hasn’t changed, staying at 45 amps keeps things simple. But if you’ve…

Hey Melissa - great question. The WFCO #WF56FR (WF-68100-AD) is rated at 100 amps on the 12V DC output side, not on the 120V AC shore power side. So it won’t “turn your RV into 100 amps.” On the AC side, this model uses a 20-amp plug and should be on…
