Clayton Off Road Overland+ Long Rear Upper Control Arms for 2020-2026 Jeep Gladiator JT

Is This for You?

• You're running 3.5"–6"+ of lift on your JT and need rear upper arms that clear the frame and body without binding — the solid 1-3/8" steel construction keeps the profile slim for clearance while delivering more tensile strength than hollow tube upper arms.
• You want full GIIRO joints at both the adjuster and axle side with zero maintenance intervals — the Overland+ spec eliminates grease fittings entirely; both ends use dual-durometer GIIRO bushings that are self-centering and maintenance-free for the life of the arm.
• You're building a long arm JT system and need upper arms that match the geometry of your long lower arms — these are engineered as a long arm system component and require a long arm bracket; they are not a bolt-in replacement for factory-length upper arms.

The Result

• Solid 1-3/8" steel construction — slimmer profile than tube uppers for frame and body clearance, with higher tensile strength under the torsional loads of rear upper arm geometry.
• Full GIIRO dual-durometer joints at both adjuster and axle side — maintenance-free, self-centering, rated for 30° of misalignment without binding at any point in the lift range.
• Long arm geometry for 3.5"–6"+ lift — corrects rear caster, pinion angle, and axle centering on lifted JT builds where factory-length upper arms produce bind and NVH.

The COR-1910030 Overland+ long rear upper control arms are engineered for the 2020–2026 Jeep Gladiator JT platform on long arm suspension systems running 3.5" to 6"+ of lift. The arm body is machined from 1-3/8" solid steel stock — a deliberate design choice for rear upper arms where a slim profile is required to clear the frame rail, body tub, and bed structure under full articulation. Solid stock at this diameter delivers higher tensile and bending strength than a comparable hollow tube, which is critical for the rear upper arm's role in controlling axle rotation and pinion angle under load. Both the adjuster end and the axle-side mount use Clayton's GIIRO dual-durometer bushing — a softer outer durometer for NVH isolation and a stiffer inner core for lateral load resistance. Self-centering geometry allows 30° of misalignment without binding through the full droop-to-compression cycle. The arm tube and housing are identical to the Premium version (COR-1910230), which uses a Johnny Joint forged rod end at the adjuster. Adjusters are field-swappable between Overland+ and Premium spec without replacing the arm. Lifetime warranty. Made in the USA. Sold as a pair.

Audit Table

Verified Fitment (OFAS Standard)

✅ Fits 2020–2026 Jeep Gladiator JT — All Trims (Sport, Sport S, Willys, Overland, Mojave, Rubicon, Texas Trail, High Altitude) — Rear Upper, Long Arm System, 3.5"–6"+ Lift
❌ Does NOT fit Jeep Wrangler JK (2007–2018) — different rear suspension geometry and arm length
❌ Does NOT fit Jeep Wrangler JL (2018–2026) — different rear upper arm pivot spec
❌ Does NOT bolt into factory short arm bracket — long arm frame bracket or conversion kit required
❌ Does NOT fit front upper control arm positions
❌ Not recommended for lifts under 3.5" — long arm geometry requires minimum lift to function correctly

Installation & Fabrication Notes

• Long arm bracket required — these arms will NOT install on a factory short arm skid plate or OEM frame bracket. Verify your long arm conversion bracket is in place before ordering.
• Adjust arm length to approximate pinion angle and caster target before installation — fine-tune at ride height after the vehicle is on the ground.
• Torque all pivot bolts at ride height, not at full droop — torquing at droop preloads the GIIRO bushing and accelerates wear.
• Rear alignment (toe, thrust angle, and pinion angle) must be set after installation — do not skip alignment on a long arm build.
• GIIRO bushings are maintenance-free — no grease fittings, no service intervals at the bushing ends.
• On JT models with ADAS: recalibrate rear sensors and cameras after suspension geometry changes per Jeep service procedure.
• Inspect solid arm body for contact points against frame, body tub, and bed floor at full droop and full compression before finalizing installation.

Wheel & Tire Fitment

Compatible with standard JT wheel and tire combinations up to 37" tires on long arm lift systems running 3.5"–6"+ of lift. Larger tire fitment (38"+) may require additional clearance modifications — verify with your builder.

Engineering Question: Are you running a factory short arm suspension system on your JT? If yes, these long rear upper arms require a long arm frame bracket — they will not mount to the OEM upper arm bracket. Confirm your long arm conversion is in place and your lift height is 3.5" or greater before ordering.
