Clayton Off Road Engine / Oil Pan Skid Plate | 1/4" CNC Laser-Cut Steel | Drain Hole | Grade 8 Hardware | Requires Clayton Crossmember | 2007–2018 Jeep Wrangler JK (2-Door and 4-Door) | SKU: COR-4108914

Verified Fitment

Does NOT fit:

• Any JK running the factory crossmember — this skid plate is incompatible with the OEM crossmember; Clayton's 3-piece long arm crossmember (COR-2108112) or HD crossmember (COR-2108212) is required
• Jeep Wrangler JL (2018–2026) — different engine and crossmember architecture; JL-specific skid system required
• Jeep Wrangler TJ / LJ — different platform
• Jeep Gladiator JT — different platform

Crossmember requirement — confirm before ordering: This engine skid plate bolts into the stock motor mounts using Grade 8 hardware, but it is specifically designed to work with Clayton's long arm suspension crossmember system. It does NOT work with the factory JK crossmember. Confirm you have or are installing either the COR-2108112 (3-piece long arm crossmember) or COR-2108212 (HD crossmember) before ordering this skid plate.

Component Specifications

Bare metal shipping — mandatory read: This skid plate ships bare metal, out of a box, not on a pallet. Surface rust and scratches are expected during shipping and are explicitly noted by Clayton as cosmetic issues that do not constitute damage and are not eligible for return, replacement, or compensation. Cosmetic marks do not affect structural performance. If you want to minimize cosmetic shipping damage, contact OFAS before ordering — Clayton offers freight pallet shipping as an alternative at additional cost.

What Is and Is NOT Included

Complete protection note: The engine skid plate is one component of a three-piece interlocking undercarriage protection system. For full underbody coverage, pair with the Clayton transfer case skid plate and the appropriate gas tank skid plate (2-door or 4-door). All three interlock together for a seamless, smooth undercarriage surface. Clayton also offers these as a complete 2-door or 4-door skid plate system rather than purchasing individually.

Critical Compatibility

The factory crossmember is the primary incompatibility gate. This is not a universal oil pan skid plate. It was specifically engineered to work within Clayton's JK long arm suspension system, dimensioned around the Clayton crossmember geometry. The factory JK crossmember creates a physical interference that prevents this skid plate from seating correctly — confirmed explicitly on Clayton's own product page.

Before ordering, confirm one of the following is already installed or being installed simultaneously:

• COR-2108112 — Clayton 3-piece long arm crossmember
• COR-2108212 — Clayton HD crossmember

If neither is present or planned, this is not the correct engine skid plate for your JK.

Bare metal shipping is non-negotiable without requesting freight pallet shipping. Surface rust appearing on arrival is expected, documented by Clayton, and not a defect claim. Prime and paint or apply preferred coating before installation to prevent ongoing corrosion.

Installation Notes

Skill level: Intermediate — bolt-on at motor mounts, but requires a Clayton crossmember to be in place first. If installing alongside a long arm kit, intermediate to advanced build knowledge is needed.

Tools required: Basic socket set and wrench, torque wrench. Wire brush or grinder and primer/paint for pre-installation surface treatment.

Installation sequence:

1. Confirm the Clayton COR-2108112 or COR-2108212 crossmember is installed before proceeding — the engine skid plate cannot be correctly positioned without it.
2. Before installation: prep the bare metal surface. Wire brush off any surface rust from shipping, apply primer and preferred paint or coating to all exposed steel. Do not install bare metal — it will rust from the underside, accelerated by road debris and moisture.
3. Position the engine skid plate under the oil pan area per Clayton's installation instructions.
4. Align the motor mount bolt locations.
5. Install using the included Grade 8 hardware — do not use lower-grade fasteners as substitutes.
6. Torque to specification.
7. Verify the oil drain hole is accessible and unobstructed — confirm you can reach the drain plug with a wrench without removing the skid plate.
8. If integrating with the transfer case skid plate and gas tank skid plate, confirm all three interlock correctly and the seams are flush before final torque.

Oil drain access: The drain hole is designed to allow oil changes without skid plate removal. Verify your drain plug falls within the drain hole profile before completing installation.

Common Questions

Will this work with my factory JK crossmember?
No. This is explicitly confirmed by Clayton — it will not work with the factory JK crossmember. You need either the COR-2108112 (3-piece long arm crossmember) or COR-2108212 (HD crossmember) installed for this skid plate to fit correctly.

My skid plate arrived with surface rust and scratches — is it defective?
No. Clayton ships this bare metal, out of a box, not on a pallet. Surface rust and cosmetic marks from shipping are expected and are explicitly excluded from defect claims and return eligibility. Clayton's own product page documents this. Prime and paint before installation to prevent ongoing corrosion. If you wanted pallet shipping to minimize cosmetic marks, that option needed to be requested before the order shipped.

Do I need to remove the skid plate for oil changes?
No. The oil drain hole is designed specifically so you can change your oil without removing the skid plate. Verify your drain plug falls within the hole profile after installation.

Is this a complete undercarriage protection system?
This is the engine/oil pan skid plate only. Complete underbody coverage for the JK also requires the transfer case skid plate and appropriate gas tank skid plate (2-door or 4-door versions sold separately). All three interlock for a seamless system. Clayton also offers 2-door and 4-door complete skid plate system packages.

Does this fit both the 2-door and 4-door JK?
Yes — COR-4108914 fits both the 2-door Wrangler JK and the 4-door Wrangler Unlimited JK across all model years and trims from 2007 through 2018.

Do I need to paint this before installing it?
Yes. The skid plate ships bare metal and will rust if installed without a protective coating. Wire brush any surface rust from shipping, prime, and paint or apply preferred coating before installation.

The Obsidian Take

The COR-4108914 is Clayton's engine/oil pan skid plate for JK builds running a long arm or HD crossmember system. It is not designed to stand alone or retrofit onto a stock JK — it is a component of Clayton's JK undercarriage protection architecture, engineered to the dimensional requirements of Clayton's crossmember geometry.

For a JK owner who is already running or planning a Clayton long arm build, this is the correct engine skid plate — CNC laser cut and CNC bent from 1/4" steel to dimensional tolerances that OEM-replacement skid plates don't attempt. The interlocking design with the transfer case skid and gas tank skid creates a smooth, seamless undercarriage surface that slides over rock faces rather than catching on them.

The bare metal shipping situation is the operational reality on this SKU and worth understanding before the box arrives. The product works exactly as designed — the bare metal is a cost and logistics decision, not a quality shortcut. Prime and paint before installation and it becomes a non-issue.

If you're building out a complete JK skid system, purchase this alongside the transfer case skid and gas tank skid rather than separately — the interlocking geometry is designed to work as a system, and having all three at once simplifies the installation sequence significantly. Clayton also offers 2-door and 4-door complete skid plate packages if you want to purchase the full system at once.

This SKU is for: 2007–2018 JK owners (2-door and 4-door) who have the Clayton COR-2108112 long arm crossmember or COR-2108212 HD crossmember installed, want proper oil pan protection integrated with the Clayton skid system, and are prepared to finish the bare metal before installation.

This SKU is NOT for: JK owners running the factory crossmember (incompatible — must replace the crossmember first), JL or JT owners (different platform), anyone expecting a drop-in bolt-on to the stock underbody, or anyone who receives bare metal and considers surface rust on arrival a defect.
