Mack specifies Stemco parts

Mack Trucks Inc has decided to make Stemco Voyager wheel seals and Stemco hubcaps factory-standard products for its medium- and heavy-duty trucks.

The Voyager seal is hub-installed and uses Stemco's dirt shield technology, a solid metal shield that prevents contamination from entering the sealing areas. A double steel case permits a positive hub installation without warping or bending.

Stemco hubcaps have a red plug that allows venting. Cast-aluminum body construction prevents warpage and enhances durability and heat dissipation.
