Flexible Financing Options For Your Engine Rebuild
At ATL Diesel, we understand that major engine repairs or rebuilds can be a significant upfront expense—especially for owner-operators, small fleets, and independent repair shops. That’s why we offer flexible financing solutions that let you get your truck back on the road without draining your cash flow. Financing your engine rebuild allows you to spread out payments over time, preserve working capital for other critical expenses, and avoid downtime that costs you more in lost revenue. Whether you're tackling a full in-frame, replacing a head or turbo, or investing in long-term performance, our financing partners make it easier and faster to move forward with confidence.

Financing FAQ & Disclosures
¹Affirm Disclosure - Rates from 0-36% APR. For example, a $700 purchase might cost $63.18/mo over 12 months at 15% APR. Payment options through Affirm are subject to an eligibility check and are provided by these lending partners: affirm.com/lenders. Options depend on your purchase amount, and a down payment may be required. See affirm.com/licenses for important info on state licenses and notifications.
²Credit Key Disclosure - Credit Key offers a dynamic line of credit, distinct from traditional leases or financed loans, providing the versatility to acquire equipment and supplies as required. Eligible applicants can access a line of credit up to $50,000, with a flexible 12-month repayment period. Pre-approval for a specific credit amount is available prior to placing an order.
