We had a great time at SEMA.  Some of our customers stopped by and we made many new connections.  Over the next few days we will be updating the website and making the show special pricing and other information available.  Please be patient with us as we just got back in town and are really tired. For now, if you want to order, please contact us (see below).  The TopDog-V is on special for $199 (with a premium mount, magnets, and 2 Donaldson bypass filters) and the TopDog-V Lite is on special for $130.  This is for 3.0" and 3.5" filters only.  We will be back at you soon with an upcated website.    


We are offering, until November 30, 2018, a lite version of TopDog-V at $130 (including s/h), and TopDog-V, our premier package.  In addition to the mated system adapter and nipple, the full version includes two Donaldson premium bypass filters, a high quality remote mount, and several rare earth magnets. TopDog-V, normally $250, will remain at the sales price of $199 (inclusive) until November 30, 2018.
