Top Armor Upgrades Every Toyota Tundra Owner Should Add in 2025

The Toyota Tundra is a powerhouse — big, capable, and built for towing, hauling, and exploring. But once you leave pavement, the factory protection just isn’t enough. Rocky lines, deep ruts, and unexpected drops can severely damage the underside of your truck if you aren’t armored up.

That’s where brands like RCI Offroad, CBI Offroad, Cali Raised, and Westcott Designs come in — all available right now on TundraLifestyle.com. These armor upgrades are proven, trail-tested, and designed to keep your Tundra protected on demanding terrain.

Here are the top armor mods you should consider this season.

1. Full Skid Plate System (RCI & CBI)

The Tundra’s undercarriage is wide and exposed, especially on rocky trails. A full skid system from RCI or CBI protects all major components:

• Front skid (engine & radiator)

• Transmission skid

• Transfer case skid

• Crossmember protection

Aluminum options keep weight manageable, while steel provides maximum durability for technical terrain.

2. Rock Sliders (CBI, Cali Raised, Westcott Designs)

The Tundra’s long wheelbase makes sliders one of the most important armor upgrades you can add. Without them, your rocker panels and doors are extremely vulnerable.

TundraLifestyle.com carries real slider options from:

• CBI Offroad – heavy-duty protection with optional kick-outs

• Cali Raised LED – strong, budget-friendly, with configurable add-ons

• Westcott Designs – premium welded sliders built for abuse

They also double as a safe jacking point on the trail.

3. Rear Differential Skid Plate

Your rear diff is one of the lowest and most frequently impacted components on the Tundra. A rear differential skid plate from RCI or CBI shields the pumpkin and prevents cracks or deformation from hard hits.

This is one of the highest ROI armor mods you can buy.

4. High-Clearance Rear Bumper Options

The stock Tundra rear bumper hangs low and dents easily. Switching to a high-clearance rear bumper from a brand like CBI:

• Improves departure angle

• Adds heavy-duty recovery points

• Reduces the chance of dragging the bumper on shelves

• Supports overland accessories like tire carriers

A great choice for frequent trail runners and overlanders.

5. Lower Control Arm (LCA) Skid Plates

LCA skids are small but crucial. The Tundra’s LCAs take constant impact on rocky trails, and bending them can destroy alignment and suspension geometry. RCI LCA skids bolt on cleanly and protect this vulnerable suspension component from direct trail damage.

They’re lightweight, affordable, and extremely effective.

Final Thoughts

Armor is the foundation of any serious Tundra build. Whether you’re exploring desert trails, mountain passes, or tight rocky sections, these upgrades — all available through TundraLifestyle.com — keep your truck protected where it matters most.
