12 July 2021: Due to a flood at my home/shop, Harbach Electronics is closed until I get this mess cleaned up and all of the damage repaired. Effective immediately I will be closed for 30-60 days or how ever long it takes to clean up and repair the damage. All pending orders will be canceled and refunded via the method of payment. I am sorry for the closure but I have to get things repaired and cleaned up. I will be back but it will be a little while. If you wish to order Dean Jacobs racing gear, please email me at and send me your phone number and I will contact you and process your order.
You can still view products, but no orders are being taken at this time. Sorry for the inconvenience!
