If you came to this page by searching for a part, please visit our online store and re-enter the part you need.
This store is under construction, and does not have all our parts listed, yet.
(A complete listing is at the bottom of this page. If you don't find the part you need in the store, please search ("find") in the list below. If it's there, please see instructions in the next paragraph.)
U. S. addresses only, please.
This link will open our online store in a new window, so you may refer back to this page for information. If you have a question about parts, or if you don't see the part you are looking for, please e-mail us. We will quote prices, add the additional part(s) you need to your order, and e-mail you a total before processing.
We are your parts source for Brister's Design & Mfg. (Mean Machine and The Go-Kart Factory), Dinli, Kartco, Brister's Thunder Karts*, Ken-Bar Streaker, Manco, Yellow Jacket*, Straight Line*, USA Karts*, Murray*, Action Motorsports*, Twister, and Tomos vehicles, as well as Briggs & Stratton, Tecumseh, and Comet. We even have a few Yerf-dog parts.
*See below for Murray, et. al., parts alert
Please note we are not engineers; we specialize in replacement parts, but we do not modify karts, nor can we give advice on modifying a kart. All sales are final -- make sure you know what you're ordering. Prices are subject to change without notice or due to typographical error; however, if your total is different from your shopping cart, we will e-mail you for authorization for the revised amount. There is no warranty whatsoever on clutches and belts. Warranty on other items will be limited to replacement of defective parts; e-mail us for an RMA before returning parts you think are defective.
In order to properly track your order, all shipped orders are accepted only via the online store. No orders are accepted by phone.
We ship only to street addresses in the United States, and charge only to credit cards with U. S. addresses. Freight is a standard $9 (contiguous 48 states). Engines, foam, special orders, and oversize objects are subject to additional freight charges. Texas residents add 6.25% state sales tax. Alaska & Hawaii e-mail for freight quote, or submit your order and we will contact you. Your shipment will normally be shipped via Fed-Ex Ground, but the USPS may be used for Alaska and Hawaii.
When you use our online store, your credit card info is submitted via a secure, encrypted connection, and it's very easy for you (or us) to track your order. Money orders are also accepted. Your credit card will not be charged until the order is ready to ship, unless it is a special order. Special orders are charged when we order the parts.
We utilize flat-rate shipping for most parts (a few oversize/overweight may be excepted) shipped within the continental United States, regardless of the size of the order. Even with multiple increases in shipping costs to us, we have not raised our rate in years. We average a loss of about $7 per Fed-ex package.
This rate may seem high on a small order, but Fed-Ex has a minimum charge of about $7 -- even if we ship a feather across town. It gets worse with home delivery, distance, weight, and size. Shipping charges also include:
We estimate we lose money on orders less than $20 (not including the flat-rate shipping charge). This is why many companies have a minimum purchase requirement. We want your future business, so we don’t have a minimum. However, we entice you to buy more with our flat rate shipping – when you get a large box of parts shipped across country for $9, that’s a deal! We cannot use regular mail envelopes, as they would be shredded by the automated equipment that reads the addresses.
If you have a small order and don't want the freight to cost more than the order, you may want to see if you need anything else ... it won't cost any more freight to add to your order.
Your order will be shipped via Fed-Ex Ground or USPS Priority Mail (delivery in 3 business days in most cases), depending upon the size, weight, and destination of the package.
Can't Find It?
You are invited to e-mail us for parts info, or for info on parts you can't find in the store. Please visit our Yerf-dog page for info on Yerf-dog parts. For Twister parts, please visit our Twister Hammerhead parts list. For Dinli parts, please visit our Dinli parts list. Please check these diagrams before contacting us about part numbers -- it's too easy for us to call an item by a different name, and we don't want to ship you the wrong part.
We cannot ship to APO/FPO, P. O. boxes (except when using USPS in Alaska or Hawaii), nor outside the United States. All sales are final; make sure you know what you're ordering. There is no warranty whatsoever on clutches and belts. Warranty on other items will be limited to replacement of defective parts. Contact us via e-mail or see the store for more warranty info.
How do I identify the torque converter belt I need? If you have the old belt, you can generally find the number on it. If you do not have the old belt, get as much information as you can -- kart manufacturer, kart model, brand of torque converter, engine horsepower -- and send us that to us in an e-mail. NOTE: Comet belts are identified by six numbers, followed by an "A" or a "C." There is no difference in the "A" and "C" belts.
How do I identify the chain I need? If you don't have a part number, look at the side of the chain. Often, the "size" of the chain will be stamped on the side, indicated by number "35," "41," "40," or "420." The picture on the side may also assist. Then, count the barrels in the chain. The chain is identified by the size and the number of barrels (length). For example, if you see "41" on the side of your chain, and count 60 barrels, you need a "41x60." Note: Chain length is always an even number. If you have an odd number of barrels, order an offset of the same size to give you the odd number. For example, if the above chain had 61 barrels, you would order a "41x60" and an "Offset, #41."
How do I identify tires? Provide tire size as written on the side of the tire (e.g., 4.10x3.50x5), plus the tread style (e.g., stud, slick, ATV, cleat).
Standard centrifugal clutches are
identified by the crankshaft size (5/8", 3/4", or 1") and by
the distance between the teeth (pitch) on the sprocket (3/8"
or 1/2"). #35 clutches are 3/8" pitch, #41 are 1/2"
I identify torque converters?
Torque converters are actually comprised
of different parts, including the DRIVER UNIT, DRIVEN UNIT,
JACKSHAFT, and BELT. There are many different types of
torque converters, and many different belts, so you will need
to be very specific when ordering torque converter parts.
We are a distributor for Comet torque converters, and carry
the replacement parts for Max Torque, as well.
(This is a partial list. If you don't see the part for
which you're looking, send us an e-mail.
Prices subject to change without notice -- e-mail us for
current pricing. Parts for Brister's Thunder Karts are
subject to supply on hand -- plus a few we're having
custom-fabricated -- as they are no longer in business.)
Dinli parts may take 3 - 4 weeks to obtain, if we do not have them in stock.
Some parts may come from assemblies (as BDM parts are no longer manufactured), and show markings from bolts; however, they are all new.

General Parts Info
(Most parts come directly from the manufacturer of the go-kart or the OEM that supplies them. Very few are generic, and are identified as such. Several of the BTK parts are custom-fabricated.)
To provide you a part, we need to know the brand and model of the item for which you're buying parts. Keep in mind the engine and go-kart are made by two different companies, and NEITHER DESCRIBES THE OTHER. That is, you DO NOT have a Briggs & Stratton go-kart!
We answer ALL e-mails. You will usually get a response within the next business day, often within the hour. (See our Hours of Operation.) If you do not get a response, it's probably because your e-mail filter is blocking our response ... that happens a lot!
If you don't get a response within 1 business day (we're closed on Sundays and Tuesdays), please click here to try an alternate e-mail address (perhaps the spam blockers won't block it and/or our response to you). Please be aware we don't check the alternate address but about once a week.
