Air-intake systems rely on multiple connected components, including hoses, elbows, pipes, reducer inserts, and clamps. Inspecting these connections can help identify wear or damage before it becomes a larger maintenance concern.

The end of summer is a great time to prepare your truck for the season ahead. Add coolant tubes and air-intake components to your preventive maintenance checklist, including rubber elbows, hoses, T-bolt clamps, intake pipes, and reducer inserts. Inspect these components for cracking, soft spots, bulging, abrasion, leaks, corrosion, or other signs of wear.

A seasonal inspection can help you identify potential problems early and keep your truck ready for the road. When it’s time for replacement parts, Grand Rock is your one-stop shop for the components you need to support your truck’s maintenance needs.

The shape of a stack can help determine how exhaust is routed and where the sound is directed. Grand Rock Straight, Curved, Miter, Bullhorn, Aussie, West Coast Curve, and Brute stacks all bring something different to a truck’s build.

The style you choose can affect the truck’s overall look, how the exhaust is routed, and how the sound is directed away from the cab. With so many options available, the right stack style can make a noticeable difference in the finished build.

Explore the range of Grand Rock Chrome stack styles and find the look that fits your truck.

Happy National Dog Day! 🐾

Truck shows are always better with a few four-legged friends around. We spotted these pups at trucking events we were in attendance, and they certainly know how to make an appearance!
