Clayton Off Road Transfer Case Skid Plate Hardware Kit for 1999-2004 Jeep Grand Cherokee WJ

Is This for You?

• You're finishing a Clayton Off Road WJ skid plate install and need the correct Grade 8 hardware to complete the job properly. Sourcing fasteners individually wastes time — this kit has everything in one order.
• You purchased COR-4106112 (skid plate only) and need the matching hardware pack. This is the exact fastener kit that ships with the full COR-4106110 assembly — sold separately for standalone skid plate buyers.
• You're rebuilding or replacing worn hardware on an existing Clayton WJ skid plate installation. Correct spec fasteners matter on a structural armor component — don't substitute with hardware store equivalents.

The Result

• Complete Grade 8 fastener kit — every bolt, washer, and lock nut required to mount the Clayton WJ transfer case skid plate, spec'd to SAE J429 Grade 8 and ASTM F835 standards.
• Yellow zinc finish on all hex cap screws and washers — corrosion resistance appropriate for undercarriage exposure on trail-driven vehicles.
• Nylon insert lock nuts included — NE Grade 8 spec prevents backing out under vibration and impact loads common in off-road use.

COR-4106111 is the hardware-only companion to the Clayton Off Road WJ transfer case skid plate. It is the identical fastener set included in the complete COR-4106110 kit. The mix of socket cap screws (ASTM F835) and hex cap screws (SAE J429 Grade 8) reflects the different mounting point geometries on the skid plate — socket caps for recessed or tight-clearance positions, hex caps for standard through-bolt locations. All fasteners are 3/8"-16 thread pitch at 3" length. Yellow zinc coating on the Grade 8 hardware provides adequate corrosion resistance for undercarriage use without the cost premium of stainless. Lock nuts are nylon insert type, which is the correct choice for vibration-prone structural fasteners — do not substitute with standard hex nuts.

• Torque to 35–40 ft-lbs for 3/8" Grade 8 fasteners in steel — confirm against Clayton Off Road installation documentation for your specific mounting configuration.

• California Prop 65 Warning: This product can expose you to chemicals including those known to the State of California to cause cancer and reproductive harm. See P65Warnings.ca.gov.

Wheel & Tire Fitment

No wheel or tire fitment restrictions apply to this hardware kit. Clearance is determined by the skid plate (COR-4106112) and suspension configuration, not the fasteners.

Engineering Question: Are you installing this hardware with the COR-4106112 skid plate only, or do you already have the COR-4106110 complete kit? If you have the full kit, this hardware is already included — confirm before ordering to avoid duplication.
