Verified Fitment
| Year Range | Make | Model | Configuration | Note |
|---|---|---|---|---|
| 2007–2018 | Jeep | Wrangler Unlimited JK | 4-Door — All Trims | Complete kit — plate + hardware |
Does NOT fit:
- Jeep Wrangler JK 2-Door — different gas tank position and underbody geometry; order COR-4108201 (plate only) or COR-4108202 (complete kit) for the 2-door
- Jeep Wrangler JL (2018–2026) — different underbody architecture
- Jeep Gladiator JT — different platform
- Early-version Clayton transfer case skid plates — this gas tank skid does not work with early-model Clayton transfer case skids; verify your transfer case skid version before ordering
4-door only — confirm before ordering. The JK and JK Unlimited have different wheelbases and different gas tank positions. The gas tank skid plates are not interchangeable between cab configurations. If you have a 2-door JK, this is the wrong product.

Material distinction: The gas tank skid is 3/16" steel while the engine and transfer case skids are 1/4". The gas tank position sits further rearward and lower in the chassis with reduced direct rock strike exposure versus the forward components — 3/16" provides appropriate protection at reduced weight for this position in the system.
Plate-only option: If you already have hardware or are replacing a plate only, order COR-4108205 ($679.00 — plate only, no hardware).
What Is and Is NOT Included
| Included | NOT Included |
|---|---|
| Gas tank skid plate — 3/16" bare metal steel (4-door configuration) | Clayton transfer case skid plate (required for full system integration — sold separately) |
| Hardware kit — necessary mounting fasteners | Engine / oil pan skid plate (COR-4108912 — sold separately) |
| COR-4108200 OEM bracket (required for stock crossmember use — sold separately, $29.00) | |
| Clayton 3-piece long arm crossmember (COR-2108112 — sold separately) | |
| Clayton HD crossmember (COR-2108212 — sold separately) | |
| Primer, paint, or coating for bare metal surface treatment |
Two installation paths — both documented:
Path 1 — Full Clayton skid system: Install with the Clayton transfer case skid plate and engine skid plate using the Clayton long arm or HD crossmember. The gas tank skid interlocks with the transfer case skid at the rear of the system. Long arm installation requires cutting one mount off the plate per Clayton's instructions.
Path 2 — OEM replacement (stock crossmember): Order COR-4108200 ($29.00) to connect the gas tank skid plate to the stock JK crossmember without the transfer case skid or Clayton crossmember. This provides gas tank protection only, without the full integrated system coverage.
Critical Compatibility
4-door vs. 2-door is the highest-risk ordering error on this SKU. The 4-door Unlimited and 2-door JK have different wheelbases and different gas tank skid plate geometry. These plates are not interchangeable — ordering the 4-door plate for a 2-door JK produces a plate that will not fit. Confirm your cab configuration before placing the order.
Cutting is mandatory for long arm system installations. When installing with the Clayton long arm system, one mount must be physically removed from the skid plate before installation — this is not optional and is not a modification you can skip. Clayton's installation instructions specify the exact cut location. If you are not comfortable with metalwork, plan for professional installation on this skid plate.
Early model transfer case skid incompatibility. If you have an older Clayton transfer case skid, verify your version is compatible with the current COR-4108204 before ordering. Clayton explicitly documents this incompatibility.
Production lead time. This is a made-to-order component. Allow 3–4 weeks for production and shipping depending on current demand. Do not order if you need this for a build with a near-term deadline without confirming current lead times.

Installation Notes
Skill level: Intermediate. Cutting of the plate is required for long arm installations — plan for metalwork capability or professional installation.
Tools required: Socket set, torque wrench. For long arm installation: angle grinder or cutting tool for mount removal. Primer and paint for bare metal surface treatment.
Production lead time: Allow 3–4 weeks for production and shipping from order placement. Confirm current lead time before ordering if working toward a build deadline.
Bare metal surface prep — do before installation:
Wire brush any surface rust from shipping. Apply primer and preferred paint, powder coat, or undercoating to all bare metal surfaces. Do not install unfinished bare metal — road salt and moisture will accelerate corrosion on unprotected steel underbody components.
Long arm system installation:
- Follow Clayton's installation instructions to identify and mark the specific mount that must be removed.
- Use an angle grinder to remove the marked mount cleanly.
- With the engine skid and transfer case skid installed and torqued, fit the gas tank skid plate last, confirming the interlocking seam with the transfer case skid is flush before final torque.
- Torque all hardware to specification.
OEM replacement installation (stock crossmember):
- Order and install COR-4108200 bracket per its installation instructions before fitting the gas tank skid plate.
- Connect the gas tank skid plate to the bracket and stock crossmember per Clayton's instructions.
- Torque all hardware to specification.
Freight pallet option: Contact OFAS before ordering if cosmetic shipping condition matters — Clayton offers freight pallet shipping to minimize cosmetic marks during transit.
Common Questions
I have a 2007 JK 2-Door — does this fit?
No. COR-4108204 is the 4-door Unlimited configuration only. Order COR-4108201 (plate only) or COR-4108202 (complete kit with hardware) for the 2-door JK.
What's the difference between COR-4108204 and COR-4108205?
COR-4108204 is the complete kit — gas tank skid plate plus hardware. COR-4108205 is the plate only, without hardware. For a new installation, order COR-4108204. If you already have hardware or are replacing a plate only, order COR-4108205.
Do I have to cut the plate?
Only if installing with the Clayton long arm system. If using the COR-4108200 bracket path (OEM replacement on stock crossmember), cutting is not required. For the HD crossmember, confirm cutting requirements with Clayton's installation instructions for your specific configuration.
Can I use this without the transfer case skid plate?
Yes — via the COR-4108200 bracket path. The bracket ($29.00) connects the gas tank skid plate directly to the stock JK crossmember, allowing you to run gas tank protection only without the full Clayton skid system. When ready to upgrade to the full system, add the transfer case skid, engine skid, and appropriate crossmember.
How long will it take to arrive?
Allow 3–4 weeks from order placement depending on current production demand. Contact OFAS before ordering if your build has a near-term deadline.
The Obsidian Take
The COR-4108204 is the final piece in Clayton's JK underbody protection system for 4-door Unlimited owners — and the one with the most flexibility in how it's deployed. It integrates into the full three-piece Clayton skid system for builders running a long arm or HD crossmember build, and it also functions as a standalone OEM gas tank skid replacement via the COR-4108200 bracket for owners who aren't running the full system but want to protect the gas tank.
The 3/16" material on the gas tank skid versus the 1/4" on the engine and transfer case skids is the correct engineering decision for the application. The gas tank sits further rearward in a less exposed position — the 3/16" plate provides adequate protection at lower weight, contributing to the smooth, continuous undercarriage profile the full system creates.
The cutting requirement for long arm system builders is the one step that catches people off guard. It's a simple cut and mount removal — not complex fabrication — but it requires an angle grinder and a few minutes of metalwork before the plate can seat correctly. If you're doing a complete long arm kit build, the cutting step happens naturally within the sequence of the installation. If you're adding this skid plate to an existing long arm build, budget an extra 20 minutes and have the right tool.
For 4-door Unlimited owners doing a complete protection build: order this with the engine skid and transfer case skid simultaneously rather than sequentially. The interlocking installation is easier when all three pieces are on hand, and you'll have a better reference for the long arm cutting dimension with all three plates in front of you.
This SKU is for: 2007–2018 JK Unlimited (4-door) owners running Clayton's long arm or HD crossmember system who want the complete gas tank skid plate kit, and 4-door owners using this as an OEM gas tank skid replacement via the COR-4108200 bracket.
This SKU is NOT for: JK Wrangler 2-door owners (order COR-4108202), owners with early-model Clayton transfer case skids (verify compatibility first), JL or JT owners, anyone with a near-term deadline who hasn't confirmed current lead times, or anyone who receives bare metal with cosmetic marks and considers that a defect.
