Frequently Asked Questions :

Do you finance?

Sorry, but no, we do not finance.

Will you ship outside of the U.S.?

Sorry, but we do not ship outside the U.S.A.

What if I can't find what I'm looking for?

We carry parts from most major suppliers, and several smaller companies. If you don't see it, or give us a call (417-468-2326). If you have any of these catalogs, you can order anything in them: Custom Chrome, Mid-USA, Biker's Choice, S&S, Midwest, Kustomwerks, Xtreme Machine, Arlen Ness, Tucker Rocky, Deep Cut Rotors, Drag Specialties, Dealer Leather, Mustang. Many of these also have online catalogs. Make a list of the part #'s and give us a call on our toll free order line: 1-866-889-7828. The more you buy, the more you save!

What about shipping?

Most parts have free shipping or shipping included in the price. If there are any special trucking charges or refundable crate charges (engines) they will be explained on the webpage.

The complete kits are shipped by truck. The chassis kits are sent by UPS or truck depending on supplier. Engines usually ship by truck, while frames are usually shipped via UPS. Most books and some small items will be sent via USPS Priority Mail. For all orders except books, we need a street address, not a P.O. box.

Charges are according to weight and where you live. On catalog orders, we give free shipping for in-stock parts orders over $295.00 (in the continental U.S. only), excluding Special Order items.

Our shipping and returns policies can be found here.

How can I feel secure about sending you money?

Steel Thunder Custom Cycles is a licensed and bonded motor vehicle dealer in the state of Missouri. You can check out our credentials here.

What is PayPal?

PayPal, a leader in online payments with over 193 million accounts worldwide, is the faster, safer way to pay and get paid online. PayPal makes online shopping fast, fun and easy, and it’s accepted by thousands of merchants all over the world. With PayPal, you don’t have to worry about exposing your financial information – PayPal never shares it with merchants.

Why pay with PayPal?

•No need to enter credit card number and address every time you make a purchase – just log into your PayPal account, confirm payment, and you’re done
• It’s safer – PayPal’s fraud detection and verification techniques are among the best in the industry
• Pay with flexibility – use your PayPal balance, bank account, credit card or debit card
• You can send money, get paid, even make donations with PayPal
Start using PayPal today!

Do I need to be a membe of PayPal to pay online?

No, you can just use your credit card via paypal.  Look for the link on your check-out page.

What do you mean by below retail?

We usually offer discounts of 10% off the retail price list on catalog orders over $100.00 (This refers to the prices in the retail price lists that come with the catalogs. Our online prices are already discounted.).

Can I apply for a dealership? Do you sell Wholesale?

No. Although we try to sell below retail whenever possible, we are a "retail" dealer, not wholesale.

Do you have such and such part for my Yamaha, Suzuki, Honda, Kawasaki or other foreign make bike?

No, sorry.

Can you match or beat the price of a competitor?

No. Our prices are as posted. If we matched the prices of the "cheap guys", we'd also have to match their customer support... which is not much. (We get phone calls and email every day from people who can not get help with an item they bought from a "cheap" source, or who have waited for back ordered parts so long they have given up. You get what you pay for.) We'd rather continue to help and support our customers, which takes time and effort.

What is meant by "rake" and "stretch" when looking at frames?

Confused about frame terminology? See tech tip #9. See tech tip #10 for a rake and trail calculator. TECH TIP PAGE

I didn't get instructions with my part. Can you send me the instructions?

Most aftermarket parts DO NOT come with instructions. Please refer to your HD manual.

Do your frames, engines, and transmissions come with MSO's?

All of our Frames, Engines, and Transmissions come with serial numbers and a Manufacturer's Statement of Origin (MSO). The MSO's are usually sent about 30 days after the item has shipped. You will receive the original copy, notarized, usually by priority mail, signature required (for your protection). Please do not lose these. There is a fee to replace a lost MSO.

What about the EPA regulations on bike building?
The EPA has recently admitted that it has no jurisdiction over individuals.  They can only regulate businesses.  As usual, you should always check with your local motor vehicle regulations before starting a build, but the EPA regulations will not effect you.  THEY CANNOT STOP YOU FROM SELLING YOUR BIKE, or regulate how many you build. 


OUTSIDE THE U.S.: To get parts and bike kits you can actually register in your country, you can look for European dealers with TUV approved products here:
