ROADMASTER REAR AUX SWAY BAR FOR FORD F53 2006 & UP, 1139-149
1139-149 Roadmaster Rear Auxillary Sway Bar for Ford F53, 1 5/8″ Diameter
This part is an add-on to the factory sway bar and fits Ford F53 V10 Chassis 24-26k GVWR, 2006-2020 and Ford F53 V8 Chassis 16-26k GVWR 2020 & Up
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 our 1/2-inch thick plate is installed above them. If you do not have enough exposed U-bolt, order one of our 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.
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 “chomoly” 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.
