ELimitation of duration

Repairs or exchanges will not extend this limited warranty beyond the described term (Item A).

FDisclaimer 1

This limited warranty is in lieu of any and all other expressed warranties of TOP TIER JAPAN. Any warranty implied is limited to the duration of this limited warranty. TOP TIER JAPAN does not assume or authorize any person to assume on its behalf any other obligation or liability. By making a purchase from TOP TIER JAPAN you agree with our warranty terms and conditions as listed in this section.

GDisclaimer 2

TOP TIER JAPAN will not be responsible for incidental or consequential damages arising from loss of use, loss of time, inconvenience, commercial loss, or any other consequential damage or loss. TOP TIER JAPAN does not provide install instructions or fitment guides — be sure to know what you are buying before making your purchase.

HWarranty claim procedure

  1. To file a warranty claim, message us through eBay and we will assist you in the procedure.
  2. The customer is responsible for all freight charges on the return of defective engines. No replacement engine will be sent until our staff have inspected and verified the returned engine. If the engine is defective, TOP TIER JAPAN will either send a replacement engine or issue a refund minus the shipping charges, at TOP TIER JAPAN's discretion.
  3. The engine MUST be returned in the same condition it was sent in. If parts are missing or the condition is altered, it will be refused by the receiving team.

Engines complete with accessories may not comply with the emission control laws of the state in which they are being sold or used. State and/or federal authorities require that you change over the emission devices from your old engine to the engine you are installing. TOP TIER JAPAN is not responsible for emissions or smog certification. The purchase price represents the cost of the long block only (cylinder head and short block).

Failure to follow these maintenance requirements voids the warranty.
  1. Must be installed, maintained, or adjusted by a certified mechanic.
  2. Set ignition to specification as recommended by the manufacturer.
  3. Change oil after 200 initial miles post-install.
  4. Check cooling system and service if rusted or contaminated with oil, and replace coolant.
  5. Must replace the timing belt, water pump, tensioner, oil filter, and spark plugs.

Receiving & Inspection

Inspect the outer packaging for visible damage before signing the release form. Freight companies will not allow you to open the crate before signing.

Shipping insurance is provided by the freight company, not by TOP TIER JAPAN LLC. If you sign the form without noting damage, the freight company is relieved of all responsibility and you will not be reimbursed for shipping damage.

Notify TOP TIER JAPAN of any damages caused by mishandling during shipping as soon as you become aware of them.

Do not sign the release form or let the driver leave until you have inspected the packaging for possible damage.

All sales are final. TOP TIER JAPAN does not offer refunds or exchanges outside the warranty terms above.

All deposits placed are non-refundable unless specified in writing from TOP TIER JAPAN.

Orders that have not yet been shipped or picked up can be cancelled for a full refund. Once an order has shipped or been picked up, the transaction cannot be cancelled.

Payment Methods

Returns Policy

30-day returns. Buyer pays return shipping. If you use an eBay shipping label, it will be deducted from your refund.
