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?

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!!

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
