Tundra Maintenance Made Easy: 5 DIY Weekend Upgrades for 2025

The Toyota Tundra is built to handle just about anything—towing, trails, and everything in between. But even the toughest truck performs best when you stay on top of regular maintenance. This weekend, grab your tools, clear the driveway, and knock out a few DIY upgrades that’ll keep your Tundra running smoother, longer, and ready for every mile ahead.

Here are five easy projects you can tackle in your own garage—no shop visit needed.

1. Refresh Your Filters and Fluids

Clean filters and fresh fluids are the simplest way to extend your truck’s life and improve performance.

Air Filter

Swap your stock filter for a high‑performance upgrade like the TRD Air Filter. It’s reusable, flows better, and helps your engine breathe easier—especially if you hit dusty trails.

Cabin Filter

If you’re noticing funky air from your vents, it’s time to replace your cabin filter. A carbon‑activated option traps odors, pollen, and debris, keeping your cab fresh.

Fluids Check

Engine oil, differential fluid, and coolant should be changed regularly, particularly if you tow or off‑road often. Pick up quality synthetic fluids and a Magnetic Drain Plug Kit to capture metal shavings between oil changes.

2. Upgrade Your Brake Setup

Brakes take a beating—especially when towing, hauling, or running larger tires. A quick weekend upgrade can restore stopping power and improve pedal feel.

• PowerStop Z36 Truck & Tow Brake Kit — designed for heavy‑duty performance and fade resistance.

• Stainless steel brake lines — increase durability and provide a firmer pedal feel.

• DOT 4 high‑temp brake fluid — ideal for mountain driving or spirited towing.

You’ll notice the difference immediately, both on and off the road.

3. Inspect & Refresh Your Suspension

A tired suspension can make your truck feel sluggish and unstable. Give it a quick inspection: check for leaking shocks, worn bushings, or uneven ride height.

If it’s time for an upgrade, go for a setup that improves ride comfort and handling:

• Bilstein 5100 Leveling Kit — a favorite for Tundra owners who want an easy lift and smoother ride.

• Old Man Emu (OME) Suspension Systems — built tough for overland travel and trail use.

A suspension refresh not only improves comfort—it restores confidence in corners and on rough terrain.

4. Battery & Electrical Health Check

Cold starts and heavy accessory use (like winches or light bars) demand solid electrical performance. Check your terminals for corrosion, clean the grounds, and test voltage.

If your battery’s showing its age, consider upgrading to a high‑output AGM battery. They handle vibration better and deliver consistent power to all your off‑road accessories.

Pro tip: Add a Switch‑Pros panel to manage your auxiliary lighting, compressors, and radios cleanly without overloading circuits.

5. Protect What You’ve Built

A little preventative protection goes a long way. Keeping your Tundra clean makes every mile easier and preserves value.

• WeatherTech Floor Liners — keep mud and moisture off your carpets year‑round.

Make these part of your post‑adventure cleanup routine, and your Tundra will look new for years to come.
