Overview
The Rubicon Express Heavy-Duty Front Sway Bar, part number RE1701, is a three-point adjustable front sway bar for the 2007-2018 Jeep Wrangler JK. Rubicon Express designed it for lifted and heavily equipped JKs,.
A sway bar resists body roll by linking the two sides of the front suspension, so a stiffer bar moves more load to the outside tire in a corner. A stiffer setting also raises the rate at which the suspension resists roll, which spreads weight more evenly across the four wheels in some conditions.
The three adjustment points let you choose a setting between the stock stiffness and a firmer one. Rubicon Express gives the range as 25-55% stiffer than the factory sway bar setting.
Key features
- Three-point adjustable design
- Stiffness 25-55% above the factory sway bar setting
- Reduces body roll for more stable handling
- Improves cornering grip on lifted JKs
- Built for heavily equipped vehicles
Sway bar stiffness and lift
Stiffer sway bars control body roll, which helps when a lifted Jeep has a higher center of gravity. The trade-off is a firmer feel over uneven ground, because the bar resists the independent movement of the two front wheels. A three-point adjustment lets you choose a middle setting that suits your tires, loads and the kind of driving you do most.
Changing sway bar stiffness affects the rest of the front end, including end links, bushings and the mounting brackets. Inspect those parts when installing a heavier bar, since the bar will load them more. Check tire rubbing at full steering lock too, because the bar’s position can shift slightly with a lift and different tire size.
- Check end link bushings for wear
- Inspect the mounting brackets for cracks
- Retighten bar hardware after the first drives
- Recheck tire clearance at full lock
