Return & Refund Policy

At Hilltop Diesel Performance, we want you to be confident that you are ordering the correct parts for your truck. Please review product descriptions and fitment information carefully before placing your order. If you have a fitment question, contact us before ordering.

Returns

We accept eligible returns within 30 days of delivery.

To qualify for a return, the item must:

Be unused, uninstalled, and in new, resalable condition
Include all original packaging, hardware, instructions, accessories, and manufacturer materials
Show no signs of installation, use, damage, contamination, modification, or attempted installation
Be accompanied by proof of purchase from Hilltop Diesel Performance

Before sending any item back, please contact us at support@hilltopdieselperformance.com to request return authorization and return instructions.

Do not send a return without authorization.

Non-Returnable Items

The following items are not eligible for return unless they were received defective, damaged, or incorrectly shipped:

Products that have been installed, used, modified, damaged, or contaminated
Electronic products, tuners, programmers, modules, or software after installation, registration, activation, or programming
Custom-built, special-order, made-to-order, or personalized products
Opened fluids, chemicals, sealants, filters, or other consumable products
Clearance or final-sale items specifically identified as non-returnable
Products missing original packaging, parts, hardware, or documentation
Items that cannot be resold as new for safety or contamination reasons

Any additional manufacturer-specific return restrictions shown on a product page also apply.

Fitment and Ordered-In-Error Returns

Customers are responsible for confirming vehicle fitment before ordering.

If you order the wrong item or determine that you no longer need the product, it may still be returned if it meets all eligibility requirements above.

Original shipping charges are not refundable on customer-choice returns. The customer is responsible for return shipping costs unless the return is caused by an error by Hilltop Diesel Performance.

Damaged, Defective, or Incorrect Items

Please inspect your order promptly after delivery.

If an item arrives damaged, defective, or different from what you ordered, contact us as soon as possible at support@hilltopdieselperformance.com with:

Your order number
A description of the issue
Photos of the product
Photos of the packaging and shipping label when applicable

Do not install a product that appears damaged or incorrect.

If we confirm that Hilltop Diesel Performance or the shipping process caused the issue, we will provide appropriate instructions for replacement, return, or refund and will cover authorized return shipping when applicable.

Refunds

Once an authorized return is received and inspected, we will notify you whether the return has been approved.

Approved refunds will be issued to the original payment method. Banks and credit-card companies may require additional processing time before the refund appears in your account.

Original shipping charges are not refundable unless the return resulted from an error by Hilltop Diesel Performance or the item arrived defective or damaged.

Items returned in used, installed, incomplete, damaged, or otherwise non-resalable condition may be refused and returned to the customer.

Exchanges

For most products, the simplest way to obtain a different item is to return the eligible original product and place a new order after the return has been approved.

Manufacturer Warranties

Some products may include a warranty provided by the product manufacturer.

Manufacturer warranty terms, eligibility, procedures, and exclusions vary by brand. A manufacturer's warranty is separate from Hilltop Diesel Performance's return policy.

We will make reasonable efforts to assist customers with manufacturer warranty information when applicable, but warranty approval is determined by the manufacturer.

Order Cancellations

We cannot guarantee cancellation after an order has entered processing, been submitted to a supplier, or shipped. Special-order or custom products may not be cancelable once processing has begun.

Return Address

Do not mail merchandise to this address until you receive return authorization and instructions.

Hilltop Diesel Performance
294 Ground Oak Church Rd
Gardners, PA 17324

Some products may need to be returned to a different authorized location or supplier facility. Always follow the return instructions provided for your specific order.
