HGM products are sold direct at list prices as well as through an extensive worldwide dealer network.

Dealers are free to set their own pricing, and often sell complete transmission / controller packages and provide full installation services. Our dealers are required to provide a first line of support to customers, and many offer value-added services like complete installation and bundled transmissions / controller packages.

Prices shown on this web site are list price, and are subject to change without notice.  If you would like to purchase products through direct sales, please contact us.

When ordering COMPUSHIFT II or other HGM products, please be sure to specify the make and model of the vehicle, the type of engine, including carburetor or fuel injection system, transmission, final drive ratio, and tire diameter.

Certain upgrades and replacement parts are application-specific and may require providing a product serial number prior to sale.

All direct sales must be paid by credit card, C.O.D., cashier's check or in-person with cash. All sales within California include sales tax. Shipping in the USA and to most countries is via UPS.

Unused or like-new products may be returned within 30 days of sale for a refund, minus the cost of initial shipping, plus a 10% restock fee.

HGM reserves the right refuse sales, service, or support.
