How Do I Make Sure the Part Fits My Engine?

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.

What Is Your Return Policy?

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.

For full details — including core returns, freight claims, refund timelines, and international return guidelines — please review our complete:

👉 Returns & Refund Policy

All returns require prior authorization. Unauthorized returns will not be accepted.

How Safe Are Online Transactions with Limitless Contracting?

Online checkout is handled through Shopify's secure checkout and the payment providers enabled for this store. Checkout pages use SSL encryption to help protect personal and payment information during transmission.

Limitless Contracting does not ask customers to send full credit card numbers by email, text, or chat. If you prefer help before ordering, contact us and we can assist with part verification and order questions.

Do You Offer Warranties On Your Products?

Yes. Most engine parts sold by Limitless Contracting are backed by warranty coverage under our Limited Warranty Policy.

Warranty coverage varies by product category and may include:

  • New Engine Components: Up to 24 months from installation
  • Cylinder Heads & Valve Train Components: 12 months from installation
  • Fuel Injector Assemblies: 12 months from installation
  • Remanufactured products may also qualify for coverage

Warranty terms apply to defects in material and workmanship under normal use and service.

Please note:

  • Warranty coverage applies only to the original purchaser
  • Coverage does not extend beyond 36 months from the invoice date
  • Installation must follow OEM guidelines
  • Claims require proper documentation and return authorization
  • Third-party products are subject to the original manufacturer’s warranty terms

Because diesel engine components operate under demanding conditions, warranty eligibility depends on proper installation, maintenance, and diagnostic verification.

For complete details — including exclusions, claim procedures, labor reimbursement limits, and manufacturer-backed components — please review our full:

👉 Warranty Policy

All warranty claims require prior authorization. Core return labels must not be used for warranty claims.

Are Your Parts OEM or Aftermarket?

Limitless Contracting LLC specializes in supplying aftermarket engine components designed to offer reliable fitment and operational durability.

We do not market our parts as original equipment. Instead, we source components through established distributor and supplier networks that focus on recognized aftermarket manufacturing and inspection standards.

Our sourcing partners focus on quality control tracking, including:

  • Standardized aftermarket quality management programs
  • Routine factory and warehouse inspection processes
  • Structured component verification protocols
  • Controlled material and dimensional tracking

Parts in our catalog are offered as aftermarket replacement components for corresponding reference numbers, with fitment details provided to help customers verify compatibility before ordering.

Can I Change or Cancel My Order?

We begin processing orders quickly to minimize downtime for our customers. If you need to change or cancel your order, please contact us as soon as possible.

Order Changes or Cancellations May Be Possible If:

  • The order has not yet shipped
  • The item has not entered freight processing
  • The product is not a special-order or custom-built item

Once an order has shipped, it cannot be canceled. In such cases, the order may fall under our standard return policy, including applicable restocking fees and return shipping costs.

Please note:

  • Special-order and custom items cannot be canceled once processing begins
  • Freight shipments may incur cancellation fees once dispatched
  • Refund timelines follow our Shipping, Returns & Refund Policy

If you need assistance, contact our team immediately with your order number so we can review the status and advise on available options.

Do you offer free shipping or price matching?

Free shipping may be available on select products or qualifying orders once a minimum order value is met. When applicable, this will typically be indicated on the product page or in promotional notices throughout the website.

If you have any questions regarding shipping eligibility, please feel free to contact our team.

We strive to keep our pricing fair, competitive, and transparent. While we do our best to offer strong value, we are happy to review reasonable price-match requests when possible. Please note that this typically excludes pricing errors, limited-time promotions, liquidation sales, auction listings, or pricing from membership-based marketplaces. If you believe you have found a comparable offer, we encourage you to reach out and our team will gladly review it.

Where are you based and where do your orders ship from?

Limitless Contracting LLC is headquartered in the greater Atlanta area in Lawrenceville, Georgia, USA.

Orders may ship from our inventory, supplier warehouses, or distribution partners depending on product availability and destination to ensure efficient and reliable delivery.

When will my order ship and how long will delivery take?

Most orders are processed and shipped within 1–2 business days, depending on product availability and order requirements. Our team works to process and dispatch orders as efficiently as possible; however, fulfillment time may vary based on factors such as order volume, product availability, and any special handling, assembly, or packaging requirements. Orders placed after business hours, on weekends, or on holidays will be processed on the next available business day.

For expedited shipping, the selected shipping service determines the delivery speed once the order has shipped. Please note that selecting expedited shipping does not guarantee immediate shipment, as order processing may still depend on product availability and preparation requirements. If your order is time-sensitive, we recommend contacting our team prior to placing the order so we can assist.

Once shipped, typical transit times are as follows:

  • Ground Shipping: Usually 1–4 business days within the United States, depending on the destination and distance from the shipping origin.
  • Freight Shipping: Typically 1–5 business days, depending on the destination, carrier routing, and delivery scheduling requirements.
  • Expedited Shipping: Delivery time is determined by the specific service selected and the carrier’s terms and conditions.

Please note that transit times are estimates and may vary depending on carrier schedules, weather conditions, and destination accessibility. If you have questions regarding product availability, shipping timelines, or delivery options, our team will be happy to assist.

How can I track my order?

Once your order ships, you will receive a shipping confirmation email containing your tracking number and carrier information.

You can use this tracking number to monitor your shipment directly through the carrier’s website.

Tracking details are typically provided:

  • Within 24 hours of shipment
  • As soon as the carrier scans the package
  • Via the email address used at checkout

For freight (LTL) shipments, tracking may include:

  • Carrier name
  • PRO number
  • Delivery appointment coordination (if required)

If you created an account during checkout, you may also log in to view your order status and shipment details.

If you have not received tracking information or need assistance locating your shipment, please contact our team with your order number and we will be happy to assist.

Do you ship internationally?

Yes, we can support international shipping on a quote-based, case-by-case basis. Sourcing and shipping options depend on part availability, destination regulations, freight requirements, and carrier limitations.

Depending on the order size and destination, shipping options may include:

  • Express parcel courier for small components
  • Air or ocean freight coordination for larger kit assemblies
  • Standard commercial invoicing and required export documentation support
  • Direct coordination with your preferred US-based freight forwarder

Transit timeframes, carrier availability, and shipping costs vary based on destination, package size, and weight. For an international shipping quote or to check destination eligibility, please contact our team with your part numbers and delivery address before ordering.

Will you ship via the U.S. Postal Service (USPS)?

No. Limitless Contracting does not ship orders via the U.S. Postal Service.

Due to the size, weight, and value of diesel engine components, we ship exclusively through reputable national carriers and freight providers, including parcel carriers and LTL freight services.

This allows us to ensure:

  • Reliable tracking
  • Proper handling of heavy or oversized items
  • Freight insurance and claims support
  • Delivery appointment coordination for large shipments

Carrier selection is based on package size, destination, and delivery requirements.

If you have a preferred carrier or freight forwarder, please contact us prior to placing your order and we will review available options.

Can I place an order by phone? How can I contact Limitless Contracting with questions?

Yes. Our team is available to assist with orders and product inquiries. Customers may place orders directly through our website, by email, or by phone, depending on what is most convenient.

If you need help selecting the correct part, confirming availability, or discussing an order, you are welcome to contact our team and we will be happy to assist.
