Description
Is This for You?
- You're running a 2007–2018 Jeep Wrangler JK Unlimited (4-door) and want to fit 37" tires without the harsh, punishing ride that most short arm kits at this lift height deliver. The Ride Right+ uses GIIRO joints to keep road noise and vibration isolated — on-road manners stay intact at 4.5" of lift.
- You want a maintenance-free suspension system that doesn't require periodic greasing at the control arm joints. GIIRO joints are self-lubricating and self-centering — no grease fittings, no maintenance schedule.
- You're building a capable JK trail rig on a budget and want a system that can grow into the Clayton Overland+ kit later. The Ride Right+ is the entry point to Clayton's JK suspension lineup — not a dead end.
The Result
- GIIRO dual-durometer bushing joints on the front upper control arms — isolate road noise and vibration while providing superior articulation over standard rubber or polyurethane bushings. Self-lubricating, self-centering, zero maintenance.
- 1-3/8" x 5/16" DOM tubing front and rear track bars — adjustable for proper axle centering after lift installation; heavier wall construction than most short arm kits at this price point.
- SealKor zinc-rich powder-coated coil springs — corrosion-resistant finish rated for the 4.5" lift height specific to this SKU; adjustable sway bar links front and rear restore proper geometry at ride height.
The COR-3108445 is Clayton Off Road's Ride Right+ short arm suspension lift kit for the JK Unlimited (4-door) platform, configured for the 4.5" lift height. At 4.5", this is the maximum lift height in the Ride Right+ JK lineup and is optimized for 37" tire fitment. The GIIRO joint system is the key differentiator at this lift height — most short arm kits at 4.5" use standard rubber or poly bushings that transmit road noise and degrade over time. GIIRO's dual-durometer construction isolates vibration while maintaining the articulation compliance needed for off-road use. Caster correction is a critical consideration at 4.5" of lift: factory JK caster is approximately 4°, and the target for proper steering feel is 5.5°. At 4.5" of lift, achieving 5.5° caster may require upgrading the front lower control arms beyond what this kit includes — evaluate after installation and before final alignment. Ships at 155 lbs. Made in the USA, backed by a Lifetime Warranty.

Installation & Fabrication Notes
- Align front and rear track bars after installation to re-center axles — both bars are adjustable for this purpose.
- Target caster: 5.5°. Factory JK caster is approximately 4°. At 4.5" of lift, achieving 5.5° may require upgrading the front lower control arms beyond what this kit includes — evaluate after installation before final alignment.
- Caster below approximately 4° will result in light or vague steering feel — do not leave caster uncorrected after lift installation.
- Adjust sway bar links after lift to restore proper sway bar geometry and on-road handling.
- Full 4-wheel alignment required after installation — use a shop familiar with lifted JK geometry.

Engineering Question: Are you running a 4-door JK Unlimited or a 2-door JK? This SKU (COR-3108445) is specifically for the 4-door Unlimited. Spring rates and geometry differ between 2-door and 4-door — confirm your body style before ordering. Also confirm whether you need front lower control arm upgrades to achieve 5.5° caster at 4.5" of lift on your specific build.
