# RC0027RZ-18 SuperPro 18mm Heavy Duty 3 Position Blade Adjustable Rear 4x4 Sway Bar Kit | Genuine SuperPro Suspension Component SuperPro Heavy Duty 4WD sway bars offer increased grip, better handling and a more precise driving experience on and off road. - Lifetime Warranty - Greater Tyre Grip On and Off Road - Designed, tested and made in Australia - Fully adjustable for complete control over your drive - Heavy duty design built to take a hit off road - Better handling, sharper steering and less body roll - High torsional steel to maintain articulation If you are carrying heavier rear loads or If you want a more precise driving experience on and off road, than upgrading to a Heavy Duty SuperPro 4x4 sway bar is a must! SuperPro, with over 40 years of experience in the automotive industry has identified that fitting larger sway bars, particularly in the rear, has two main effects, vehicle balance in terms of understeer and oversteer, and increased roll resistance. Both effects can provide increased overall handling and safety benefits when driving 4WD. A larger rear sway bar, or the addition of a rear sway bar, helps in providing more neutral characteristic in the handling. This is due to the increase in roll stiffness at the rear, which changes the loading of the rear wheels under conditions of increased cornering load. ### Kit Specifications Diameter (mm) 18 Diameter (in) Fraction 23/32" Diameter (in) Decimal 0.708 Material Solid Spring Steel Sway Bar Adjustment Type 3 Point Adjustable Adjusting the sway bar's soft to hard setting will modify its torsion regidity, causing the sway bar to operate as per the size below. ### Sway Bar Adjustment Settings Setting Effective Bar Size (mm) % Change vs Previous Setting % Stiffer Than OE Soft - Comfort / low grip 17 mm \- +27.4% Medium - Balanced 18 mm +25.7% +60.2% Hard - Maximum roll control 19 mm +24.1% +98.9% ### Packaged Weight and Dimensions Units cm/kg in/lbs Weight 4.4kg 9.7lbs Length 150cm 59.06" Width 20cm 7.87" Height 50cm 19.69" ### Misc.
