Hellwig 7775 Rear Sway Bar for 2018-2026 Jeep Wrangler JL/JLU 4WD 7/8in

Vehicle Fitment

• 2018-2026 Jeep Wrangler JL (2-Door, 4WD, All Trims, All Engines)
• 2018-2026 Jeep Wrangler JLU Unlimited (4-Door, 4WD, All Trims, All Engines)

Fitment Notes

• Fits all JL-generation Wrangler configurations - Sport, Sport S, Sahara, Rubicon, Willys, 4xe (plug-in hybrid), and 392 (6.4L V8) - in both 2-door (JL) and 4-door Unlimited (JLU) body styles.
• This bar reuses the factory rear end links - end links are NOT included in the kit.
• Compatible with stock height and lifted applications - fits with all JL/JLU lift kits without lift-height restrictions.
• Note: Adding a stiffer rear sway bar will increase rear roll stiffness and reduce rear suspension articulation when compared to stock. Owners who prioritize maximum off-road axle articulation should evaluate this trade-off against their use case.
• Does NOT fit the JK-generation Wrangler (2007-2018) - this bar is designed specifically for the JL platform (2018+).
• Does NOT fit the 2021+ Jeep Wrangler 4xe or 392 in ways that differ from standard JL - both are confirmed fitments.

Features

• Purpose-built 2-position adjustable rear sway bar for the 2018-2026 Jeep Wrangler JL/JLU - replaces the factory undersized bar with a larger-diameter unit that significantly improves rear lateral stability and on-road handling confidence.
• 7/8" (0.875 in.) diameter solid, heat-treated 4140 chromoly spring steel - noticeably larger than the factory bar, delivering improved resistance to rear body lean during cornering, towing, and highway crosswinds.
• 2-position adjustable rate design with forged 2-hole end attachment points - tune from stiffer (inner hole, for maximum anti-roll and towing) to more compliant (outer hole, for a balance of control and trail use).
• Significantly reduces the rear body sway, highway crosswind sensitivity, and corner lean that Wrangler owners commonly experience - especially when the vehicle is lifted, carries rooftop tents, bumpers, or other heavy accessories.
• Reuses factory rear end links for a clean, OEM-integrated installation with no aftermarket link hardware required.
• High-durometer polyurethane bushings included for superior roll resistance, reduced noise and vibration, and longer service life than rubber.
• Gray hammertone powdercoated finish for corrosion resistance in all weather and trail conditions.
• Heat-formed as a single piece from 4140 chromoly steel - more structurally consistent at the bends versus cold-bent alternatives.
• Bolt-on installation using factory rear axle mounting locations - complete with all hardware and installable with basic hand tools in approximately one hour.
• ISO 9001:2015 certified manufacturing at Hellwig's Visalia, California facility. Made in the USA. Backed by a Limited Lifetime Warranty.

Product Description

The Hellwig 7775 Rear Sway Bar is a direct-fit, 2-position adjustable replacement upgrade engineered for the 2018-2026 Jeep Wrangler JL and JLU. The JL Wrangler's factory rear sway bar is intentionally undersized - Jeep prioritizes rear axle articulation for off-road capability over on-road roll stiffness. The result is a Wrangler that handles everyday driving with noticeably more rear body sway than most drivers want, particularly when the vehicle is lifted, loaded with accessories like rooftop tents or steel bumpers, or driven at highway speeds in crosswinds or alongside large trucks. The Hellwig 7775 addresses this directly with a solid 7/8" heat-treated 4140 chromoly bar - meaningfully larger than stock - that transforms the Wrangler's on-road composure while remaining bolt-on compatible across the full JL generation.

The 2-position adjustable end design gives owners meaningful control over rear stiffness. The inner hole setting delivers maximum anti-roll stiffness - the right choice for towing, heavy accessory loads, or daily commuting. The outer hole provides a slightly more compliant setting that balances road performance with some retention of rear suspension compliance for light trail use. The bar reuses the factory rear end links in all applications, and the installation is straightforward using factory axle mounting points, completable with basic hand tools in approximately one hour. All mounting hardware and polyurethane bushings are included.

Fitment covers all 2018-2026 JL-platform Wrangler variants across both body styles and all trim levels - Sport, Sport S, Sahara, Rubicon, Willys, 4xe (plug-in hybrid), and 392 (6.4L V8) - in both 2-door JL and 4-door JLU Unlimited configurations. The bar is also lift-kit agnostic, confirmed to work across all JL lift configurations without height restrictions. Owners who do significant technical off-roading where maximum rear axle articulation is critical should weigh the trade-off against improved on-road behavior. Built at Hellwig's ISO 9001:2015 certified Visalia, California facility and backed by a Limited Lifetime Warranty, the 7775 is widely regarded as one of the most impactful and cost-effective handling upgrades for the JL Wrangler platform.
