• How to Determine If Longer U-Bolt Kit is Needed for Roadmaster RM-1139-149 Anti-Sway Bar Kit
  You can easily determine if you'll need the # RM-590050-10 Extended U-bolt kit by taking a quick measurement. Measure the length of the existing U-bolt that extends through the factory nut. If you can add a 1/2 inch to account for the thickness of the plate used to attach the new anti-sway bar and have 3 threads remaining, you won't need the kit. Otherwise, you will. Since you currently have a 1/2 inch of thread exposed, I'm afraid you're going to come up short on the U-bolt length and...

• 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...

• Rear Anti-Sway Bar and U-Bolt Replacement Kit Installation on a 2017 Canyon Star on F-53 Chassis
  The rear anti-sway bar # RM-1139-149 will fit the V10 Ford F-53 chassis if the gross vehicle weight rating is 22K, 24K, or 26K. Based on your description you will need # RM-590050-00 u-bolt replacement kit. I have included a link to a video showing an example installation for you. It is a good idea to lift the RV and then use jack stands to support just the axle. With the vehicle supported elsewhere and the axle supported by jack stands it is less likely for the vehicle to "slip" off the...

• Are Larger U-Bolts Needed For Installing A Roadmaster Rear Anti-Sway Bar On A F-53 Chassis
  The mounting plate for the Roadmaster Rear Anti-Sway Bar Item # RM-1139-149 will be attached to the U-bolts so you'll be able to look at the U-bolts and see if there's going to be enough to threads to place the plate on and retighten the nuts. For U-bolts with a square top, order kit # RM-590050-00. For U-bolts with a round top, order kit # RM-590050-10. I've attached a video that will walk through installation step by step for you as well.

• Are Extended U-Bolts Needed To Install the Roadmaster Rear Sway Bar On a 2018 Jayco Precept 36T
  The Extended U-Bolt Kit part # RM-590050-00 (square) or part # RM-590050-10 (round) may be needed to install the Roadmaster Rear Anti-Sway Bar part # RM-1139-149 on your 2018 Jayco Precept 36T but I cannot give you a yes or no answer.

• Recommended Anti-Sway Bar for 2006 Fleetwood Bounder Gas Engine on Ford F53 Chassis
  I did a little bit of research and it looks like 2006 Fleetwood Bounder with a gas engine was built on a Ford F53 chassis like you mentioned, so the correct rear anti-sway bar for your rig with a GVWR of 20,500-lbs is the Roadmaster # RM-1139-143. It should be noted that the factory u-bolt may not be long enough for the factory nut, washer and 1/2" plate when used with this bar. If that is the case, if you have square top u-bolts will need # RM-590050-00, and if you have round top u-bolts...

• How to Determine if Longer U-Bolts are Needed When Upgrading Anti-Sway Bar for 2015 Vista 27N
  To determine whether or not a longer U-Bolt kit is needed when you install the Roadmaster Rear Anti-Sway Bar # RM-1139-146 on your 2015 Winnebago Vista 27N Motorhome you need to look at your current U-Bolts and take a measurement. The bracket that comes with the anti-sway bar kit is 1/2" thick so you just have to make sure that you have 1/2" of extra space on your current U-Bolts plus room to have 3 threads left over. If you have enough room then you don't need the longer U-Bolts. If you...

• Tools Needed to Install Roadmaster Rear Anti-Sway Bar # RM-1139-149
  The installation manual for the Roadmaster Rear Anti-Sway Bar # RM-1139-149 along with the Extended U-Bolt Kit # RM-590050-10 simply calls for a torque wrench and "general hand tools". When we installed this kit on the 2017 Ford F-53 we used a 13/16 inch socket, a 5/16 inch socket, a 15/16 inch wrench/socket, an 18mm wrench/socket, and a 16mm socket. I have attached this installation video below that you can also check out.

• Front and Rear Sway Bars Needed for a 2012 Winnebago 37F on a 2011 Ford F-53 Chassis
  You are correct in that you will want to be looking at fits for the 2011 Ford F-53 chassis as opposed to the 2012 year. For your Class A motorhome with a V10 you will want to use the Roadmaster Front Anti-Sway Bar # RM-1139-148 which is 1-3/4" in diameter, and the Roadmaster Rear Anti-Sway Bar # RM-1139-149 which is 1-5/8" in diameter. Since your motorhome is rated for 24,000 lbs the bar with the 1-5/8" diameter will work great. Please note that you will want to check to ensure there...

• Recommended Sway Bar For 2019 Thor Motor Coach Challenger 37FH On Ford F-53 Chassis 24,000 GWR
  I recommend Roadmaster Rear Anti-Sway Bar part # RM-1139-149 and the front Roadmaster Front Anti-Sway Bar part # RM-1139-148 for the 2019 Thor Motor Coach Challenger 37FH On Ford F-53 Chassis 24,000 GWR. The factory anti-sway bars are not as thick as these after market bars so they do a better job at improving the drive-ability and reducing the sway by balancing the weight. I have attached an installation video of the bars for your reference. I do recommend to check to ensure there is...

• Front and Rear Anti-Sway Bars for 2018 Holiday Rambler Reno 29M on Ford F-53 Chassis
  It looks like your Holiday Rambler Reno M29 was built on a Ford F-53 chassis. For the front anti-sway bar, you'd use # RM-1139-148. For the rear, you'd use # RM-1139-149. Just a note about the # RM-1139-149- if the factory U-bolts aren't long enough, you'll need longer ones. To determine if what's currently there will work for you, measure how much of the current u-bolt is extending pas the retaining nut. If there isn't 1/2 an inch plus at least three threads sticking out, you'll need...

• 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...

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.

• Recommended Anti-Sway Bars for 2005 Fleetwood Bounder 34F
  For your 2005 Fleetwood Bounder 34F, I recommend replacing the rear sway bar first. The rear needs more stability than the front based on the axle placement and weight so it will make the greater impact. I recommend the Roadmaster Rear Anti-Sway Bar # 1139-144. This retains the factory sway bar. The factory u-bolt may not be long enough for the factory nut, washer and 1/2" plate. If not, square top u-bolts will need # RM-590050-00, and round top u-bolts will need # RM-590050-10. To...

Since you only have half an inch that you can see you will want to go...

• 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...

• How To Increase Stability and Reduce Sway Of 2020 Bounder Motorhome on 2019 Ford F-53 Chassis
  It sounds like you meant that the Fleetwood Bounder is on a 2019 Ford F-53 chassis which is very common. The first step in increasing the stability of the 2020 Fleetwood Bounder on the 2019 Ford F-53 chassis is to replace the factory sway bars. The factory sway bars, especially on the Ford Chassis are not as good as the aftermarket sway bars at keeping the motor home in line. I recommend Roadmaster Front Anti-Sway bar part # RM-1139-148 and Rear anti-sway bar part # RM-1139-149. Before...

  Since your 2005 Fleetwood Southwind 32V is built on the Ford F-53 Chassis and is under 34' long you will need the Roadmaster Rear Anti-Sway Bar # RM-1139-143.

You may also be interested in the Front Anti-Sway Bar # RM-1139-148, and Steering Stabilizer # RM-RBK22-RSSA to complete your suspension enhancement...

• 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...

• Recommended Rear Sway Bar For A 2005 Monaco Monarch On A Ford F53 Chassis
  Though we cannot see your cart, I can definitely tell you that if you are getting a lot of issues with sway and or body roll, I recommend going with the Roadmaster Rear Anti-Sway Bar # 1139-144. This is 1-3/4" thick 4140 chromoly steel for superior strength that will do a much better job than stock bars. With that said, this actually will not replace the original sway bar and you will keep that installed. So if your older bushings are looking a bit worse for wear, I do recommend getting...

• Anti-Sway Bars for 2019 Tiffin Allegro Open Road Motorhome
  According to what I was able to find, the 2019 Tiffin Open Road Allegro is manufactured on a Ford F-53 Chassis. The exact sway bar you need will depend on the GVWR of your motorhome, which should be mentioned on the manufacturer's ID plate along with the VIN and other important information. For 15,700 lb, 18,000 GVWR models less than 34 feet long, use # RM-1139-146 which would install in conjunction with the existing sway bar. For 22,000, 24,000 or 26,000 lbs, use # RM-1139-149. The factory...
