MCB343031 (Gasket Kit - Major Overhaul)

We strongly recommend providing your Engine Serial Number (ESN) or VIN before placing an order. Diesel engine components can vary by engine model, CPL, and production year — even when part numbers look similar.

At Limitless Contracting, we verify compatibility whenever an ESN or VIN is provided to help ensure you receive the correct part the first time.

To avoid delays or incorrect orders:

• Enter your ESN or VIN on the product page (if required)
  
• Or contact our team for verification before purchasing
  
• If you're unsure, we’re happy to assist you

Our goal is to eliminate guesswork and keep your equipment running with minimal downtime.

Limitless Contracting offers a structured return policy designed specifically for diesel engine components and heavy-duty parts.

Eligible items may be returned within 30 days of the invoice date, provided they are:

• Unused and uninstalled
• In original packaging
• In resalable condition
• Accompanied by an approved RMA number

Certain items such as electrical components, gaskets, open kits, special-order items, and installed parts are non-returnable.

Approved returns are subject to a 15% restocking fee, and shipping charges are non-refundable.
