The Hercules Terra Trac TG Max has been one of our bestsellers, with its aggressive tread design, pleasant ride and unmatched durability it's been a #1 choice for many of our customers. But with that, all good things must come to an end. The TG Max is unfortunately being replaced by a new design. It currently is out of production but is still available in limited sizes and quantities. If this was your tire of choice come on into Mack's and get some on order before they're Sold out. They are priced to sell!

We joined in on Clark's 250th parade celebration of the USA. Brought out the '78 Chrysler State Police Car loaded up some Mack's Service future generations, some candy, and hit the streets. What a great event and enjoyed by all! Awesome job Clark! This is the start of us celebrating 70yrs of Mack's Service serving Clark. More to come!

Classic car season is here. We had this Mustang come in for some mechanical adjustments and installed a set of rear air shocks, which not only helped improve its classic appearance but also assisted with a better ride for cruisin. Get those classics out and bring them to Mack's Service, we'll get them back on the road.
