We stock about 80% of the items in our catalog, but those items manufactured in speciality shops, such as mounts, exhaust systems, fiberglass products and those items manufactured to adapt our products with other manufacturers parts, are not kept in stock. This is due to the limited sales of these items (i.e., only ordered once a year). If an item is back ordered, we will do the best we can to expedite your order. Orders requiring machine work take a minimum of two weeks In House, before return shipment.


Orders are shipped via UPS, US Postal Service and DB Schenker. Shipping of orders is completed twice weekly. Normal service by ground is 2 to 7 working days depending upon your location in the US. Most books and videos are sent by US Priority Mail. Actual shipping costs will be charged to the customer at the time of shipment. Crated items will incur a crating fee.
