• Best Way to Reduce Sway on 2017 Coachmen Mirada Select 37TB Motorhome on Ford F53 Chassis
  The 2017 Coachman Mirada Select 37TB is built on the Ford F53 chassis. To reduce the sway, you are absolutely on the right track with the parts you are requesting. I recommend the following parts: Roadmaster Rear Anti-Sway Bar for Motor Homes # RM-1139-149 along with the Extended U-Bolt Kit # RM-590050-00 if the factory bolts are not long enough to accommodate the factory nut, washer, and a new 1/2 inch plate. The extended u-bolts may not be needed if you have enough room on your factory...

• What Rear Sway Bar Fits A 2008 Georgetown on Ford F-53 22,000 Lb Motorhome Chassis?
  Hello Larry, Thanks for writing in! Yes, you will want the Roadmaster Rear Anti-Sway Bar # RM-1139-149 for your 2008 Forest River Georgetown on the Ford F-53 22,000 lb chassis. It fits models with either the V8 or V10 engine and has a 1-5/8" diameter bar to help reduce that side-to-side sway and body roll you feel from wind, passing trucks, and uneven roads. One thing I really like about this setup is that it installs in addition to your factory sway bar, so the factory bar stays right...

• Best Suspension Upgrades For 2007 Gulf Stream Independence 22,000 GVWR on Ford Chassis
  Hey Jaran, Great questions, and regarding the anti-sway bars, I definitely recommend upgrading to a larger size. When it comes to anti-sway bars on motorhomes like your Gulf Stream, bigger is definitely better. The larger the diameter of bar, the higher the roll stiffness it gives you, and that's the most important aspect of handling sway. The rear anti-sway bar is the best upgrade, followed by the front anti-sway bar, and then steering stabilizer for added control in the heavy crosswinds....

• Recommended Suspension Upgrade for 2018 Fleetwood Bounder 36D on Ford F-53 Chassis
  I strongly recommend both front and rear anti-sway bars, and for your 2018 Fleetwood Bounder 36D on a Ford F-53 chassis with a GVWR of 22,000 lbs and a V10 engine the correct rear anti-sway bar is the Roadmaster Rear Anti-Sway Bar # RM-1139-149 while the front anti-sway bar is # RM-1139-148. For the rear bar you may need to use Extended U-Bolt Kit # RM-590050-00 if you find the square OEM U-bolts on your Bounder are too short. The Extended Kit gives you U-Botls which are 15-3/4".

• Comparing Anti-Sway Bars and Axle Stabilizers for an RV on a 2014 Ford F-53 Chassis
  Anti-sway bars and axle stabilizers are similar but they do different things. An anti-sway bar helps more with body roll which is that tilting side to side motion whereas an axle stabilizer helps for with the tail-wag motion. Both are going to make the RV more stable and more pleasant to drive. You can use both but if you wanted to try just one first I would recommend the anti-sway bar. For a the 2014 Ford F-53 chassis # RM-1139-143 fits RVs that are less than 34 feet long. Check to ensure...

• Rear Anti-Sway Bar for 2017 Thor Motor Coach Hurricane 31S With 2016 Ford F53 Chassis
  Yes, the Roadmaster Rear Anti-Sway Bar for Motor Homes, # RM-1139-146 will work on your 2017 Hurricane 31S with the 2016 Ford F53 Chassis with either a V8 or a V10. The anti-sway bar will use the weight of the axle as a brace against the chassis so that pressure to one side of the motor home is countered by the sway bar. It minimizes the side-to-side movement that cargo shift, wind or passing trucks can cause. On some applications longer u-bolts are required to install this kit. For square-end...

• Installing Extended U-bolts for Roadmaster Rear Anti-Sway Bar 1139-143 on 2004 F-53 Chassis
  The Roadmaster Rear Anti-Sway Bar for Motorhomes # RM-1139-143 can use your factory u-bolts if they are long enough. If they are not, then Roadmaster recommends using the 7/8 inch diameter u-bolts that are longer (most likely the larger diameter due to length needed to ensure strength). I've attached a couple photos from the installation instructions to assist with the size and torque. When torque specs are so large either a large special torque wrench is required or installers are...

• Sway Bars and Steering Stabilizer For With a 2023 Fleetwood Flair 29M On Ford F53 V8 18,000LB GVWR
  As your 2023 Fleetwood Flair is on a Ford F53 V8 18,000LB GVWR chassis you have 2 choices for the rear sway bar. The Roadmaster Rear Anti-Sway Bar # RM-1139-149 is 1-5/8" in diameter and mounts in addition to the factory sway bar. They also offer the 1-3/4" Rear Sway Bar # RM25VR.

• Are Longer U-Bolts Needed for Anti-Sway Bar on 2019 Forest River Georgetown GT5 Motorhome
  Since the U-bolts on your 2019 Forest River Georgetown GT5 motorhome have 1-1/2" exposed thread, it is very unlikely you will need the longer 15-7/8" square U-bolts # RM-590050-00 or 20-1/4" long round U-Bolts # RM-590050-10 to install the Roadmaster Rear Anti-Sway Bar # RM-1139-149. The plate is 1/2" thick (see accopmanying photo) so you will still have an inch of exposed thread, and worst-case scenario is you can order the longer U-bolts if need be, though I am confident you will not...

  Thanks for reaching out, Blake! The best way to upgrade your 2011 Newmar Canyon Star 3920 Toy Hauler is to start off with anti-sway bars, then a steering stabilizer, and then add some suspension enhancement. Here are the parts I recommend for your application: - Front Anti-Sway Bar # RM-1139-148 - Rear Anti-Sway Bar # RM25VR (Might need square # RM-590050-00 or round # RM-590050-10 U-Bolts if factory U-Bolts can't accommodate 1/2 plate) - Steering Stabilizer (there currently aren't...

• Recommended Suspension Enhancement For a 1996 Fleetwood Bounder 28T on Ford F-53 Chassis V8 Engine
  For your 1996 Fleetwood Bounder 28T of the Ford F-53 chassis with the V8 I recommend the Roadmaster Rear Anti-Sway Bar # RM-1139-143. This will add a sway bar to the rear of your suspension to reduce sway and provide better stability when turning. First you will want to check your U-Bolts on your rear axle to determine if they are going to be long enough to allow for the sway bar. A 1/2" thick plate will need to be added to the U-bolts. We have the Square Extended U-Bolt Kit # RM-590050-00...

• Recommended Sway Bars For a 2011 Tiffin Allegro RV Motorhome On a Ford F-53 22,000LB Chassis
  I recommend the Roadmaster Front Anti-Sway Bar # RM-1139-148 for the front of your 2011 Tiffin Allegro on the Ford F-53 22,000lb chassis. This will replace your current way bar with a thicker and stronger 1-3/4" sway bar and uses polyurethane bushings versus rubber. For the rear the Roadmaster Rear Anti-Sway Bar # RM25VR will add a 2nd sway bar to the rear of your chassis. This bar is also 1-3/4" in diameter like the front with polyurethane bushings. You will need to measure the the amount...

• Recommended Handling Enhancement Kits for F-53 Based Four winds Hurricane 34B Class A Motorhome
  In general it is best to start anti-sway efforts at the front of the motorhome, to prevent such handling issues from then rolling through the entire vehicle. For a front anti-sway bar I suggest Roadmaster's # RM-1139-148 which works on both V8 and V10 models. This no-drill install replaces the OEM sway bar with a beefy 1-3/4-inch-diameter 4140 chromoly steel bar that includes polyurethane bushings that last a long time. This will usefully stiffen the front end response. Next up in priority...

It if it longer, then you will instead use # 1139-144. The rear anti-sway is the most help out of all components. You will likely need longer u-bolts # RM-590050-00 or # RM-590050-10. Next, the Front Anti-Sway Bar # RM-1139-148 is the next best step followed by the Roadmaster Reflex Steering Stabilizer with Mounting Brackets for...
