Financing FAQs
Does checking my eligibility affect my credit score?
No. Checking your eligibility with Affirm or Shop Pay Installments uses a soft credit check that has no impact on your credit score. You'll see your real-time rate and payment options before you commit to anything.
Affirm and Shop Pay Installments will notify you before a payment is due. Late or missed payments may result in a late fee and can affect your ability to use financing in the future — see the lender's terms at checkout for full details.
Affirm and Shop Pay Installments are available on qualifying orders through checkout. Eligible order amounts and available plans are shown automatically at checkout based on your cart total.
Most orders qualify, including full builds — ECUs, fuel systems, suspension, and more. Eligibility and available plans depend on your order total and creditworthiness, confirmed in real time at checkout.
Both are backed by Affirm's lending partners, so the terms are similar. Shop Pay Installments is built into checkout with no extra sign-up and splits orders into 4 interest-free bi-weekly payments. Affirm offers longer monthly plans, including 0% APR on qualifying purchases. Pick whichever payment cadence fits your budget.
