4.5 Inch Lift Kit | Long Arm | Jeep Wrangler JK (07-18) 4-Door

Built for Jeep JK owners who want maximum ground clearance and trail-ready geometry without compromise, this 4.5-inch long-arm lift preserves OEM driveline angles while opening up 35-inch tire clearance. You get boxed lower control arms, a reinforced track bar, and geometry correction that keeps your Jeep planted on road and rock.

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

• Boxed lower control arms — forged steel with internal gussets to eliminate flex and handle aggressive terrain without premature wear.
• Reinforced track bar — maintains lateral stability and corrects caster for predictable handling at all speeds.
• Caster-corrected geometry — keeps your JK tracking true and reduces the darty, twitchy feel common on lifted vehicles.

Out back

Rear long arms, spring perches, and a new track bar mount complete the geometry package. The system is tuned to work with OEM driveshaft angles, so you avoid vibration and premature wear.

Pick your shocks

• NX2 Nitro Series — comfortable daily driver with 15 compression and 25 rebound clicks. Great for mixed terrain and weekend trails.
• FOX 2.0 Performance Series — tuned for moderate off-road use with better ride control and fade resistance than Nitro.
• FOX 2.5 Performance Elite — premium damping with advanced internals for serious rock crawling and high-speed desert running.

Important notes

• This kit is engineered for 2007–2018 Jeep Wrangler JK 4-door models only. Verify your model year before ordering.
• Maximum tire clearance is 35 inches with proper wheel offset and backspacing — oversized tires without backspacing adjustments can rub in articulation.
• The long-arm design preserves factory driveline geometry, but confirm your driveshaft angle with your installer to rule out vibration post-install.
• If your JK is equipped with electronic stability control (ESC) or a factory electronic locking differential, sensor calibration may be needed after install — ask your tech.

Why customers pick this at Road Runner

• BDS long-arm kits are engineered for caster correction — no wandering on the highway, no clunky feel on washboard.
