Why Install Coachbuilder Shims on Your Tundra?

Okay, guys, let's talk about why you'd even want to install Coachbuilder shims on your Tundra. There are several reasons, and they're all pretty compelling. First off, many Tundra owners want to eliminate that factory rake – you know, where the rear of the truck sits higher than the front. This isn't just an aesthetic thing; it can affect your truck's handling and appearance, especially when you're hauling or towing. Coachbuilder shims offer a simple, effective way to level out your Tundra, giving it a more balanced and aggressive look. This levels the stance, providing a more aesthetically pleasing and balanced look. Furthermore, by lifting the front, you gain additional clearance, which is great for off-roading or simply navigating uneven terrain. You'll notice an improvement in both on-road handling and off-road capability. Plus, adding a bit of lift allows you to fit larger tires, enhancing both the look and performance of your Tundra. And let's not forget the improved ground clearance, making those pesky parking curbs a little less worrisome. Ultimately, installing Coachbuilder shims is about improving the overall form and function of your Tundra, making it not only look better but also perform better in various driving conditions. It’s a win-win!

Essential Tools and Materials

Alright, before we get our hands dirty, let's make sure you've got all the right tools and materials. Trust me; there's nothing worse than getting halfway through a project and realizing you're missing something crucial. Here’s a comprehensive list to get you started:
