This Warranty Policy governs all products sold by Bennett Truck Center and works together with our Returns, Cancellations & Order Policies. By purchasing from Bennett Truck Center, you agree to the terms below.

Third-Party Brands — Manufacturer Warranty Only

For third-party branded parts, all warranty coverage, where applicable, is provided solely by the part's manufacturer, under the manufacturer's own terms, duration, and claim procedures. Bennett Truck Center will assist in submitting manufacturer claims as a courtesy; the manufacturer's inspection and determination are final.

Bennett Truck Center & Hack Nation Branded Products

Bennett Truck Center branded and Hack Nation branded products — including Hack Nation long blocks and engine builds — are private-label products. Warranty on these products is administered directly by Bennett Truck Center. Coverage is limited to repair or replacement of the defective part itself, at Bennett Truck Center's option, for a period of twelve (12) months from the invoice date, unless a longer period is specified in writing at the time of sale. Certain product lines — such as new transmissions and new differentials — carry longer coverage, typically 3 to 5 years, as stated on the invoice or provided by the manufacturer. All other terms of this Warranty Policy — including Never Covered, Warranty Void Conditions, the Claim Process, and the Limitation of Liability — apply in full to branded-product warranty claims.

No-Questions-Asked Warranty (Select Products)

Select products — such as Bennett Truck Center branded turbochargers and exhaust manifolds — carry a No-Questions-Asked warranty, as designated on the invoice or product listing. Within the applicable warranty period, Bennett Truck Center will replace the failed part without requiring failure analysis. No-Questions-Asked coverage applies to replacement of the part itself only: it never covers labor, removal, installation, towing, downtime, or any other cost or damage listed under Never Covered, and the Limitation of Liability applies in full. The complete failed part must be received back by Bennett Truck Center, whole, before any replacement ships — this applies even under No-Questions-Asked coverage, and a clean ECM report (see ECM Requirements) is still required. No-Questions-Asked status applies only where expressly designated by Bennett Truck Center and does not extend to any other product.

Never Covered

Bennett Truck Center does not provide or reimburse, under any circumstances: labor (removal, installation, or diagnosis), towing, freight, travel, lodging, fluids, filters, machine work, rental or replacement equipment, downtime, lost profits or revenue, cargo loss, or any incidental or consequential damages.

Warranty Void Conditions

Any applicable warranty is null and void if the part or unit is: disassembled, opened, or tampered with in any way; installed improperly or by unqualified personnel; operated with insufficient or incorrect lubrication or coolant; subjected to overheating, contamination, abuse, misuse, neglect, accident, or modification; tuned or programmed above factory horsepower or torque ratings; used in racing, pulling, or other competition; used outside its intended application; or where the ECM has been erased, reset, or shows a logged critical event (see ECM Requirements). Proof of proper installation and maintenance may be required for any claim.

Claim Process

All claims must be submitted to Bennett Truck Center through our Support Request form or by phone or text at 737-204-9316 before any teardown, repair, or return, and must include the invoice number, engine serial number, and a description of the failure. Unauthorized teardown or repair voids the claim.

The standard claim process requires the part(s) to be returned, freight prepaid, to Bennett Truck Center or to the manufacturer, at Bennett Truck Center's direction, for inspection and failure analysis. Failure analysis typically takes an estimated 30 to 90 days from receipt, and no credit, replacement, or refund is issued until the analysis is complete and the claim is approved.

At its sole discretion, Bennett Truck Center may offer to evaluate a claim remotely by photos, video, email, or phone as a courtesy. Remote evaluation is never required of Bennett Truck Center, does not replace the standard process, and Bennett Truck Center may require physical return and full failure analysis at any time, including after a remote evaluation has begun. Customers may not withhold payment, offset, or charge back amounts owed while a claim is pending.

Mandatory Return Before Replacement

On every warranty claim, return, exchange, or swap — under every coverage tier, including No-Questions-Asked — the complete original part must be received back by Bennett Truck Center, whole and unaltered, before any replacement, credit, or refund is issued. No replacement ships in advance. If the original part is not returned, or is returned incomplete, the claim is denied in full (100%).

ECM Requirements

A clean ECM report showing no logged critical events is required for all warranty coverage. All warranties are denied where: (a) the ECM shows a logged critical event — including but not limited to overheat, low oil pressure, low coolant, or overspeed — experienced while the part was in service; (b) the engine is or has been tuned or programmed above its factory horsepower or torque rating; or (c) the ECM has been erased, reset, reflashed, or had data deleted. An erased or reset ECM is treated as concealment of a critical event and results in denial of the claim. Bennett Truck Center may, at its sole discretion, extend good-faith coverage despite any of these conditions; any such accommodation is discretionary, case-by-case, and is not a waiver of these requirements for any other claim.

Disclaimer of All Other Warranties

EXCEPT FOR ANY APPLICABLE MANUFACTURER WARRANTY AND THE BRANDED-PRODUCT WARRANTY DESCRIBED ABOVE, ALL PARTS ARE SOLD "AS IS" AND "WITH ALL FAULTS." BENNETT TRUCK CENTER DISCLAIMS ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. No employee, agent, estimate, or invoice creates any warranty on behalf of Bennett Truck Center unless designated as a warranty in writing and signed by an authorized manager.

Limitation of Liability

Bennett Truck Center's total liability arising from any part or order, under any legal theory, is limited to the purchase price of the part giving rise to the claim.

Commercial Use

Parts sold by Bennett Truck Center are intended for commercial heavy-duty truck applications and are sold for commercial use.
