4.5 Inch Lift Kit | Jeep Wrangler JK (07-11) 4-Door

Built for Jeep enthusiasts who want serious ground clearance without sacrificing ride quality — this 4.5-inch lift kit raises your JK Wrangler and opens up bigger tire options while preserving the geometry your driveline depends on. BDS engineering keeps caster angles correct, so you get a smooth highway ride and predictable handling even at elevation.

Installed and serviced at Road Runner Wheels & Tires. Most kits go in the same day. Call (678) 400-6467 to schedule.

What you get up front

• Upper and lower control arms — geometry-corrected for caster and camber, so your steering stays true and tire wear stays even.
• Coil springs — rated for the new height and load, engineered to work in tandem with your chosen shock package.
• Sway bar links — extended to match the new ride height and maintain suspension articulation.
• Bumpstops and hardware — all fasteners and protective components included to complete the install.

Out back

Rear coil springs matched to the front, extended sway bar links, and all necessary brackets to keep your rear axle tracking true at the new height. Transfer case re-indexing is included in the kit design, so power transfer stays efficient.

Pick your shocks

• BDS NX2 Nitro Series with Disconnects — smooth, comfortable daily driver; Nitro gas pressure controls fade over long heat cycles. Best value for trail days and highway miles alike.
• FOX 2.0 Performance Series with Disconnects — velocity-sensitive damping, speed-sensitive valving, and disconnect technology for technical terrain; more precise than NX2, tracks better over rough ground.
• FOX 2.0 Performance Series with Fixed Links — same FOX 2.0 tuning as Disconnects but solid links front-to-rear; slightly stiffer feel on small bumps, rock-solid articulation when you're aired down.
• FOX 2.5 Performance Elite with Disconnects — premium-grade internal floating piston (IFP) design, dual-speed compression and rebound adjusters for fine-tuning ride character. Track-proven dampening; the gold standard for serious rock crawlers and high-speed desert running.

Important notes

• Vehicles equipped with factory air suspension are not compatible with this kit — confirm your model is coil-spring only before ordering.
• OE wheels may require offset/backspacing adjustment; aftermarket wheels with 4.75" or greater backspace are strongly recommended to avoid suspension interference.
• Maximum tire diameter is approximately 35 inches; confirm your tire choice with us before install to prevent rubbing under full articulation.
• Installation is complete same-day at Road Runner; disconnect modules (if selected) are tested on-site to ensure proper electronic function.

Why customers pick this at Road Runner

• Corrected caster geometry means better highway manners and longer tire life — not a compromise.
