Workhorse W22 and Workhorse W24 Class A Motorhome Suspension, Steering, and Handling Upgrade

Roadmaster anti-sway bars deliver a noticeable improvement in vehicle stability and handling for today’s most popular motorhome chassis. The Roadmaster 1259-105 kit features a 1-5/8" diameter front sway bar that works in conjunction with the factory "box-style" stabilizer bar and includes heavy-duty polyurethane bushings for enhanced control and reduced body roll.

Designed for straightforward installation, Roadmaster anti-sway bars are precision-engineered from powder-coated 4140 chromoly steel and paired with high-performance polyurethane bushings for maximum durability and long-lasting support beyond factory components. Each kit includes all required mounting hardware, upgraded polyurethane bushings, and detailed installation instructions.

what is the average amount of time it take to install this product....billable time the mfg suggest ( Kenneth Silverman, 10/06/2023 )
Roadmaster says average installation time for this kit is 2 hours.
I am installing the Roadmaster #1259-105 1-5/8" front stabalizer bar on my 2004 Newmar MountainAire (Workhorse W22) chassis. The driver's side B425 bracket isn't fitting as described in the instructions. When I install the 3/4" bolt thru the existing hole in the frame the bracket is about 1/2" above the part of the frame that is below the bracket. If I rotate the bracket to be level (parallel to the frame) the bracket presses hard against the power steering hose. I fear that would wear a hole in that hose over time, so prefer another option. Would a better option be to drill two holes in the frame to position the B425 bracket so it's sitting on the frame below it and is away from the power steering hose? If so, would I need to drill two holes on the passenger side so that that bracket is even with the B425 bracket? ( Ron Brugger, 07/20/2021 )
Hi Ron, can you please call in and speak with one of our technicians regarding the fitment issue?
I have a blue ox true center steering dampener will the sway bar hit it ( jorey, 03/02/2019 )
There won’t be any interference.

Picture doesn't seem to be what others are showing as 1259-105? Other sites show many more pieces to 1259-105. Thanks in advance, Jim c

( Jim Chambers, 08/19/2015 )

Jim,

The 1259-105 that we sell is the same as all the others, we just didn't have images of the installation hardware before but that is now added. Thank you for bringing that to our attention!
