Clayton Off Road Engine Skid Plate for 2007-2018 Jeep Wrangler JK Long Arm Kit

⚠️ IMPORTANT: This skid plate is designed specifically for the Clayton JK long arm kit. It will NOT work with the factory cross member. A Clayton 3-piece long arm cross member or HD cross member is required.

⚠️ SHIPS BARE METAL: Surface rust and cosmetic scratches during shipping are normal and are not considered damage. These items are not eligible for return, replacement, or compensation for cosmetic issues. Contact Clayton for a freight pallet quote if you want to avoid cosmetic shipping damage.

Is This for You?

• You have a Clayton JK long arm kit installed (3-piece long arm cross member or HD cross member) and need an engine skid plate designed to work with that cross member geometry — this 1/4" oil pan skid plate was designed specifically to work in conjunction with the Clayton 2007–2018 JK long arm kit. It will not fit or function with the factory JK cross member. If you have a factory cross member, this skid plate is not compatible.
• You want a 3D Solidworks-designed, CNC laser-cut and CNC bent 1/4" steel engine skid plate with an oil drain access hole and Grade 8 hardware that bolts to the stock motor mounts — designed using 3D Solidworks CAD software and CNC laser-cut and bent for maximum accuracy, strength, and fit. The oil drain access hole allows oil changes without removing the skid plate. Bolts to the stock JK motor mount locations using Grade 8 hardware.
• You understand this skid plate ships bare metal in two packages and that cosmetic surface rust or scratches during shipping are normal and not eligible for return or replacement — this skid plate ships bare metal (uncoated) in two packages. Surface rust and cosmetic scratches during shipping are a normal result of bare metal shipping and are not considered damage — they do not affect performance. Prime, paint, or apply your preferred finish after installation. Contact Clayton for a freight pallet shipping quote if you want to minimize cosmetic shipping issues.

Engineering Question: Do you have a Clayton long arm kit installed with the 3-piece long arm cross member or HD cross member? This skid plate will not fit the factory JK cross member — confirm your cross member before ordering. Also confirm you have finishing capability (paint, primer, or undercoating) — this skid plate ships bare metal and should be finished after installation to prevent rust.
