1139-212 Roadmaster Rear Auxiliary Sway Bar for Ford F53, 1 3/4" Diameter

Roadmaster anti-sway bars are built to offer significantly more resistance to sway than stock bars

Bigger is better - Roadmaster anti-sway bars have a thicker diameter than stock bars (often, a quarter to three-eighths of an inch more). Each incremental increase in diameter has an exponential effect on performance - on average, torsional roll stiffness is increased by 30 percent with every eighth-of-an-inch increase in diameter. In plain English, RSS anti-sway bars offer up to 90 percent more resistance to sway.

A high-grade alloy - RSS anti-sway bars are made of 4140 "chromoly" steel (a chrome and molybdenum alloy) which is considerably stronger and more durable than the standard spring steel (a 1020 grade) used in many stock anti-sway bars.

A better pivot point - RSS anti-sway bars have polyurethane bushings, which, unlike the rubber used in stock bushings, is impervious to gas, oil and ozone corrosion, is more resistant to abrasion, and doesn't buckle under heavier load weights.

This part is a rearward facing add on (auxiliary) rear anti-sway bar. The factory rear anti-sway bar is not removed. Each kit comes complete with heavy-gauge mounting hardware, easy-to-follow instructions, and the bushing lubricant.

Applications:

Ford F53 V10 with 20,500 lb GVWR (2006-2020)*; Ford F53 V10 with 22,000 lb GVWR (2006-2020)*; Ford F53 V10 with 24,000 lb GVWR (2006-2020); Ford F53 V10 with 26,000 lb GVWR (2006-2020); Ford F53 V8 with 16,000 lb GVWR (2021-Current); Ford F53 V8 with 18,000 lb GVWR (2021-Current); Ford F53 V8 with 20,500 lb GVWR (2021-Current); Ford F53 V8 with 22,000 lb GVWR (2021-Current); Ford F53 V8 with 24,000 lb GVWR (2021-Current); Ford F53 V8 with 26,000 lb GVWR (2021-Current)

Application Notes:

*The 1139-149 and 1139-212 will fit 20,500 lb and 22,000 lb GVWR V10 chassis, although the 1139-145 is an easier installation.

No Thor Outlaw Toy Haulers. Also, some coach builders, such as Tiffin, will add extra bracing that may interfere with installation. Please verify your coach has adequate clearance.

This kit uses a flat plate that is held in place by the leaf spring U-bolts on the rear axle. Check to ensure there is enough exposed U-bolt below the nut to accommodate the factory nut and washer once the 1/2-inch thick plate is installed above them. If you do not have enough exposed U-bolt, order one of the U-bolt replacement kits. For U-bolts with a square top, order kit 590050-00. For U-bolts with a round top, order kit 590050-10.

CHECK YOUR GVWR TO ENSURE CORRECT FIT!

It's easy to get mixed up when checking your vehicle weight rating. Ford F53 suspension upgrades are designed to fit a specific GVWR (Gross Vehicle Weight Rating). We have provided a photo (second photo after main image) as an example to help you determine the correct rating for your RV. You can find this sticker inside your RV on the wall behind the driver's seat most of the time.

Please ensure you DO NOT use the GCWR (Gross Combined Weight Rating) as a reference for fitment. This will give you the combined weight rating of your chassis and towing a vehicle. This will be a larger rating than the GVWR and change the application, in many cases, causing fitment issues.

Motorhome chassis manufacturers use different rear axles for different weight ratings on the chassis.
