Clayton Off Road Rear Shock Bracket & Control Arm Skid Plates | Pair | 1/4" Steel Base / 3/16" Side Bracing | Bolt-On | Grade 8 Hardware Included | 2018–2026 Jeep Wrangler JL (2-Door & 4-Door) | SKU: COR-4109030

Verified Fitment

Does NOT fit:

• Jeep Gladiator JT (2020–2026) — different rear shock and control arm bracket geometry; order COR-4110010 for the JT rear lower control arm bracket skid plates
• Jeep Wrangler JK (2007–2018) — different rear suspension architecture; not confirmed for this SKU
• Jeep Wrangler TJ or LJ — different rear suspension architecture

Component Specifications

Construction rationale: The 1/4" base plate provides the primary impact resistance against direct rock strikes — the loading scenario these brackets face during rock crawling and trail use. The 3/16" side bracing adds lateral rigidity to prevent deformation under angled impacts and side loading. The composite construction optimizes weight vs. protection without requiring weld-in reinforcement.

Grade 8 hardware upgrade: The included Grade 8 hardware (9/16-18" and M12) replaces the factory lower control arm and shock mount bolts. Factory bolts are adequate for OEM use but can exhibit minor play at the mounting interfaces under trail loads. Grade 8 replacement hardware eliminates that slop, providing a tighter connection at both the control arm and shock mount locations — this is a suspension stability benefit independent of the protective function of the skid plates.

What Is and Is NOT Included

JL front skid note: The COR-4109020 front lower control arm skids for the JL require welding — they are not a bolt-on product. If you are building a complete JL skid system, plan for professional installation on the front skid plates. The COR-4109030 rear skids are bolt-on only and do not require welding.

Critical Compatibility

JL vs. JT — not interchangeable.

The JL Wrangler and JT Gladiator share a platform but have different rear shock bracket and lower control arm bracket geometry. Clayton manufactures a separate skid plate for the JT (COR-4110010). The JT version uses different hardware (5/8" and 3/8" vs. the JL's 9/16-18" and M12) and different plate geometry. Do not order COR-4109030 for a Gladiator JT.

Shock clearance — verify with oversized bodies.

The skid plates are designed with optimized clearance for large aftermarket shocks. The vast majority of common performance shock bodies (Fox 2.0, 2.5; Bilstein 5100 and 5160; Falcon SP2 3.1 and 3.3) are confirmed compatible. However, if you are running an unusually large shock body diameter beyond standard performance shock specs, verify physical clearance before installation.

Front skid note — welding required for COR-4109020.

Clayton's package notes explicitly flag: "Front lower control arm skids require welding." This applies to the COR-4109020 front skid, not to this rear skid (COR-4109030), which is 100% bolt-on. If you're researching a complete JL skid system, the front and rear skids have different installation requirements.

Installation Notes

Skill level: Beginner to intermediate — 100% bolt-on, no cutting or welding required.

Tools required: Basic hand tools (socket set and wrench), torque wrench.

Installation sequence:

1. Confirm vehicle is a 2018–2026 Jeep Wrangler JL before beginning.
2. Safely lift and support the vehicle — rear suspension accessible at ride height or slight droop is acceptable.
3. Remove the factory lower control arm mounting bolts and shock mount bolts at the rear bracket locations on both driver and passenger sides.
4. Position the driver-side skid plate over the OEM bracket location — confirm the plate seats flush against the bracket faces.
5. Install the included Grade 8 9/16-18" and M12 hardware in place of the removed factory bolts per Clayton's installation instructions.
6. Repeat for the passenger side.
7. Torque all Grade 8 hardware to Clayton's specified torque values.
8. Cycle the suspension through full droop and full compression — confirm no contact between the skid plates and the shock bodies or control arms at either extreme.
9. Confirm the drain holes on both plates are unobstructed after installation.

No cutting or welding: This is a zero-modification installation. The OEM bracket locations accept the skid plates directly. No drilling, cutting, or welding is required or should be performed.

Common Questions

Do these fit the Jeep Gladiator JT?
No. The JT uses different rear shock bracket and control arm bracket geometry. Order COR-4110010 for the JT rear lower control arm bracket skid plates. The JT version also uses different hardware (5/8" and 3/8") — confirming these are platform-specific products.

Do I need to weld anything for installation?
No. The COR-4109030 rear skids are 100% bolt-on. No cutting or welding is required. Note that Clayton's front lower control arm skids for the JL (COR-4109020) do require welding — that's a different product with different installation requirements.

What does the Grade 8 hardware do that the factory bolts don't?
Grade 8 hardware is a higher tensile strength specification than factory replacement hardware and provides a tighter, no-play fit at the lower control arm and shock mount locations. This eliminates minor bolt slop that develops at those mount points under trail loading — a suspension stability benefit beyond the protection function of the skid plates themselves.

Will these clear my Fox 2.5" or Bilstein 5160 shocks?
Yes — the skid plates are designed with optimized clearance for large aftermarket shocks, and standard performance shock bodies including Fox 2.0/2.5 and Bilstein 5100/5160 series are compatible. If running an unusually oversized shock body beyond standard performance shock diameters, verify physical clearance before installation.

Are these sold as a pair?
Yes — COR-4109030 includes both the driver-side and passenger-side rear shock bracket and control arm skid plates. One order covers both sides.

Do I need a complete Clayton skid system, or can I run these alone?
These rear skids install independently — no other Clayton components are required. They are also included in Clayton's JL performance packages if you're building a more comprehensive protection or suspension system.

The Obsidian Take

The COR-4109030 addresses a specific vulnerability on the JL's rear suspension: the shock mounts and lower control arm brackets sit exposed below the frame rail in a position that makes them first contact on rock strikes during crawling. A direct hit to a factory shock bracket can bend it, damage the shock body, or compromise control arm alignment — none of which are trail-repairable problems.

The 1/4" base plate and 3/16" side bracing construction is the right architecture for this application. The base plate takes the primary impact load; the side bracing prevents lateral deformation under oblique strikes — the kind of loading that happens when a rock slides along the underside during a climb rather than hitting square-on. Both failure modes are covered.

The Grade 8 hardware is the understated benefit on this SKU. It's not just a fastener swap — it's a suspension upgrade. Anyone running a JL on trail who has noticed minor imprecision in rear suspension feel at the lower control arm or shock mount interfaces will notice improvement after installation. The factory bolts tolerate that slop; the Grade 8 hardware doesn't.

The bolt-on installation is the practical advantage over aftermarket rock guards that require cutting or welding. These go on in the driveway with hand tools and come off the same way if you need to service the shock or control arm without having to grind out welds.

This SKU is for: 2018–2026 Jeep Wrangler JL owners (2-Door and 4-Door, all trims) who wheel on rocky terrain and want bolt-on protection for their rear shock mounts and lower control arm brackets, along with the Grade 8 hardware suspension stability upgrade that comes with it.

This SKU is NOT for: Gladiator JT owners (order COR-4110010), JK Wrangler owners (different architecture), anyone looking for front lower control arm skids (that's COR-4109020 and requires welding), or anyone who needs a no-drill/no-modification front skid solution — the front skids for the JL are a different product class.
