RC Fabrication 2nd Gen Tundra / 2nd Gen Sequoia Spindle Gussets

Reinforce one of the most heavily stressed areas of the factory front end with the RC Fabrication 2nd Gen Tundra / 2nd Gen Sequoia Spindle Gussets.

These weld-on spindle gussets are designed to strengthen the OEM spindle upright by reinforcing a known weak point that becomes increasingly vulnerable under larger tires, harder off-road use, suspension upgrades, and repeated impact loads. For customers who use their trucks aggressively in dirt, desert, trails, or other demanding conditions, spindle reinforcement is an important step toward improving front-end durability and long-term reliability.

Built from precision laser-cut, pre-bent steel, these gussets are designed to provide added rigidity while keeping fitment and installation straightforward for the installer or fabricator.

Overview

As front suspension loads increase, the factory spindle upright is exposed to more stress than it was originally designed to handle. Larger tires, heavier wheel and tire combinations, rough terrain, and more aggressive driving all place added force into the spindle and steering assembly.

The RC Fabrication 2nd Gen Tundra / 2nd Gen Sequoia Spindle Gussets are designed to reinforce that area by adding structure where it is needed most. The goal is to help reduce spindle flex, improve resistance to bending, and better support the factory upright under real-world abuse.

For best overall spindle longevity, these gussets should be used as part of a properly thought-out suspension system, especially on trucks seeing frequent off-road use.

Features

• Weld-on spindle reinforcement for the factory upright
• Designed to strengthen a commonly stressed area of the OEM spindle
• Precision laser-cut and pre-bent for consistent fitment
• Steel construction for added rigidity and durability
• Intended to help reduce spindle flex under increased load
• Suitable for off-road, lifted, and larger-tire applications
• Supplied as a driver and passenger pair

Why Reinforce the Spindle

Factory spindles were designed around stock suspension geometry, stock tire size, and normal on-road operating conditions. Once those conditions change, the spindle becomes one of the front-end components subjected to substantially higher loads.

These gussets are intended for vehicles running:

• Larger tires
• More aggressive off-road use
• Suspension upgrades
• Higher-impact terrain
• Heavier wheel and tire combinations

Reinforcing the spindle upright helps create a stronger assembly better suited for the demands of modified and hard-used trucks.

Construction

Each pair is manufactured from precision laser-cut steel and formed for consistent fitment. This allows the installer to spend less time correcting fitment and more time preparing the spindle properly for welding and finishing.

These are weld-on components and should be installed by a qualified fabricator or technician familiar with spindle preparation, fit-up, and welding procedures.

Compatibility

Designed for the following applications:

• 2007–2021 Toyota Tundra
• 2008–2021 Toyota Sequoia

Customers should confirm vehicle application before ordering.

What’s Included

• One pair of pre-bent steel spindle gussets
  • Driver side
  • Passenger side

Installation Notes

Welding and surface preparation are required for installation. Proper fitment verification, prep work, and welding technique are important to ensure the best final result.

Intended Use

These spindle gussets are intended for customers looking to strengthen the factory spindle upright for more demanding use. Whether the vehicle is used for trail driving, desert use, overland travel, towing on rough terrain, or general off-road abuse, reinforcing the spindle upright is a practical upgrade for improving front-end durability.
