Shipping Policy

01 Same-Day Shipping

In-stock parts ordered by 3:00 PM Mountain Time on a business day ship the same day. Orders placed after the cutoff, on weekends, or on holidays ship the next business day.

Custom and built-to-order items (such as performance heads) ship after the build is complete — the product page lists the lead time, and a specialist confirms it on your order.

02 Free Freight Over $500

Orders over $500 shipping within the lower 48 states qualify for free standard ground freight. The discount applies automatically at checkout to the goods subtotal (before taxes and core charges).

• Applies to standard ground service only — expedited and air upgrades are billed at cost
• Oversize / freight-class items may ship LTL; free freight still applies to qualifying orders
• Does not apply to Alaska, Hawaii, U.S. territories or international destinations

03 Methods & Carriers

We choose the fastest, best-protected method for each part. Small parts go parcel; heavy or oversize items go LTL freight.

04 Estimated Transit Times

Business days after the order ships, for standard ground from Denver, CO. These are carrier estimates, not guarantees.

05 Heavy & Freight Items

Cylinder heads, inframe kits and other heavy parts ship on a pallet via LTL freight. A few things to know so delivery goes smoothly:

• The carrier calls to schedule a delivery appointment for residential addresses
• Liftgate service is available if you don't have a dock or forklift — ask at checkout
• Delivery is curbside; have help or equipment ready to receive the pallet
• Inspect the pallet before signing (see Shipping Damage)

06 Order Tracking

You'll get a tracking number by email as soon as your order ships. Parcel shipments update automatically; for LTL freight you'll receive the carrier's PRO number and contact info to schedule delivery.

Lost the email or no updates after 2 business days? Call or text us and we'll chase it down.

07 Shipping Damage & Claims

Every shipment is insured. Damage is rare, but if it happens we make it right — fast — when you follow these steps:

• Inspect before you sign — note any damage on the delivery receipt
• Photograph the packaging and the part before unpacking further
• Report damage within 5 business days of delivery
• We file the carrier claim and ship a replacement — you keep working

08 Core Return Shipping

Orders with a refundable core charge include a prepaid return label for most parts. Send your old, drained, rebuildable core back within 60 days to get your core deposit refunded. Full details are on our Returns & Refund Policy.

09 Backorders & Lead Times

We carry deep stock, but occasionally an item is on backorder or built to order. When that happens:

• The product page and your order confirmation show the expected lead time
• We'll contact you with options if a date changes materially
• Multi-item orders can ship complete or in stages — your call

10 Alaska, Hawaii & International

We ship to Alaska, Hawaii and U.S. territories at calculated rates (free-freight promotions don't apply). International orders are quoted case-by-case; the customer is responsible for all duties, taxes and customs fees. Call a specialist for an international quote.
