Grand Rock - 3" Wide x 6", 7" or 8" Diameter Peterbilt or Kenworth 4-Hole S3 Chrome Mounting Bracket
The Grand Rock 3″ Wide x 6″ Diameter Kenworth 4-Hole S3 Chrome Mounting Bracket is a heavy-duty exhaust mounting accessory engineered to support the exhaust stack or related components on Kenworth trucks. Designed with a 3-inch-wide band and sized to fit 6-inch diameter stacks, this chrome-plated bracket uses a four-hole mounting pattern that helps distribute load evenly and provides a secure attachment point between the truck’s frame or cab bracket and the exhaust system.
Built with durable polished stainless steel and finished in high-shine chrome, it not only adds structural support to keep the stack properly aligned under vibration and load but also enhances the visual appeal of the truck’s chrome exhaust setup. Grand Rock products like this are known for their corrosion resistance and long-lasting performance in demanding heavy-duty applications.
