Shipping, Returns & Warranty

Last updated: June 5, 2026

Everything you need to know about how orders are paid, shipped, warrantied, and (where applicable) returned. If anything here is unclear, email [email protected] or call (530) 531-8332 — we would rather answer a question before you order than after.

Deposits & payment

Remanufactured long blocks, short blocks, and other made-to-order builds are reserved with a deposit paid at checkout. The deposit amount is shown on the product page and in your cart. The remaining balance is due before the item ships. When your build is complete and ready to ship, we email you a Stripe payment link (or invoice) for the balance and any freight charges; nothing ships until the balance is paid. Smaller parts, kits, and apparel are paid in full at checkout.

• Deposit refunds: refundable in full within 7 days of order, provided machining and build-specific parts ordering have not yet begun.
• After work begins: the deposit is non-refundable — the labor and parts committed to your build cannot be resold.
• Unsure where your build stands? Email or call before cancelling and we will tell you.

Shipping

• Long blocks, short blocks, and cylinder heads ship via ground LTL freight.
• Parts, kits, and apparel ship via standard ground carrier.
• Freight quoting: freight for large items is quoted per order based on destination and dimensions and confirmed before we invoice the balance.
• Lead times: vary by product and current shop workload. We confirm your estimated ship date after the deposit is received.
• Delivery: title and risk of loss pass to you upon delivery to the carrier. Delivery dates are estimates and not guaranteed.

Core charges & core returns

Many of our remanufactured products are exchange units, which means we expect your original assembly (the "core") back after you receive the replacement.

• The rebuildable core must be returned to us within 30 days of the date you receive the replacement.
• If a rebuildable core is not received within 30 days, the no-core price shown on the product listing (typically an additional $1,500) will be charged to the payment method on file, and the applicable warranty will be voided.
• Core credit is refunded to your original payment method within a reasonable time after we receive and inspect the returned core.
• Return freight for the core is the customer's responsibility unless we state otherwise in writing.

Warranty (remanufactured long & short blocks)

Our remanufactured long blocks and short blocks carry a 24-month / 24,000-mile limited warranty (whichever comes first) from the original date of delivery, against defects in workmanship and materials. Coverage is parts only — labor, removal, reinstallation, towing, rental, and consequential expenses are not covered.

To keep the warranty valid, the buyer must:

• Follow the documented break-in procedure supplied with the engine.
• Maintain the vehicle per the manufacturer's specifications, using appropriate fluids and filters.
• Return the required core within 30 days.

The warranty does not cover failures resulting from tuning outside factory specifications, forced induction beyond the engine's design, missed maintenance, overheating, oil starvation, contaminated or improper fuel, accident, or other causes outside of RVJ Machine's control.

Warranty coverage on other products (parts, kits, apparel) is as described in the applicable product listing.

Returns & cancellations

Because our engine products are built or remanufactured to order, we do not accept returns of finished goods for reasons other than a warranty claim.

• Cancellations are permitted within 7 days of the order date, subject to the deposit refund terms above, provided machining and build-specific parts ordering have not yet begun.
• Warranty claims must be initiated by contacting us before returning any product. Unauthorized returns will not be accepted.
• Non-engine products (parts, kits, apparel): contact us within a reasonable time of delivery to discuss a return; return shipping and any restocking are handled case-by-case.

Filing a warranty claim

1. Email [email protected] or call (530) 531-8332 with your order number, the vehicle's mileage at time of failure, and a description of the issue.
2. Include photos or a shop diagnosis if available.
3. We'll respond with the next step — typically a return authorization and shipping instructions. Do not ship anything back before we authorize it.
