Fabtech Performance System

2016–2021 Toyota Tundra 2WD/4WD

Part #: K7055DL

Overview

The Fabtech 6" Performance System with 2.5" drilled and slotted crossovers and rear drilled and slotted rotors is a comprehensive suspension upgrade designed specifically for Toyota Tundra models from 2016 to 2021. Engineered to enhance off-road capability while maintaining excellent on-road manners, this system provides a significant lift and improved handling for your truck. Whether you're tackling rugged trails or upgrading your daily driver, this kit offers a perfect balance of performance, durability, and protection.

Built with off-road enthusiasts in mind, the Fabtech Performance System transforms your Tundra into a more capable and aggressive vehicle. It features extended-length ductile iron steering knuckles that are designed to operate within the factory steering geometry, ensuring proper turning radius and steering response even with oversized tires and wheels. The system also relocates the factory lower control arms using high-arched 1/4-inch thick steel crossmembers, which include an integrated differential skid plate for added protection against off-road obstacles. This setup not only improves ground clearance but also enhances durability and reliability during demanding off-road adventures.

Key Features

The Fabtech Performance System incorporates several innovative features to deliver superior performance and longevity:

• Extended Ductile Iron Steering Knuckles: Designed to maintain factory steering geometry, these knuckles provide precise handling and durability under off-road conditions.
• High-Arched Steel Crossmembers: Constructed from 1/4-inch thick steel, these crossmembers relocate the factory lower control arms, increasing ground clearance and off-road capability.
• Integrated Differential Skid Plate: Protects the differential and undercarriage from rocks, debris, and rough terrain, ensuring long-lasting performance.
• Retained Factory Sway Bar: The system preserves the factory front sway bar, utilizing sway bar drops to maintain ride quality and stability.
• Drilled & Slotted Crossovers & Rotors: The 2.5-inch drilled and slotted crossovers and rear rotors improve heat dissipation and braking performance, reducing fade during aggressive driving or towing.
• Heavy-Duty Construction: All components are built from high-quality steel and ductile iron, ensuring strength and resistance to wear and tear in demanding environments.
• Designed for Off-Road & On-Road Use: This system enhances off-road capability without sacrificing daily driving comfort or safety.

Construction & Design

The Fabtech 6" Performance System is meticulously engineered with a focus on durability and performance. The extended-length ductile iron steering knuckles are crafted to withstand the rigors of off-road driving while maintaining precise steering response. The high-arched steel crossmembers are fabricated from thick steel to provide robust support and increased ground clearance, essential for navigating challenging terrain. The integrated differential skid plate is designed to absorb impacts and protect critical drivetrain components, ensuring your vehicle remains reliable after off-road excursions.

The drilled and slotted rotors are precision-machined to improve heat dissipation and reduce brake fade, especially during extended off-road use or towing. The system's components are TIG-welded and constructed with high-quality materials, ensuring a long service life and resistance to corrosion. Overall, the design emphasizes a balance between strength, functionality, and ease of installation, making it a reliable upgrade for serious off-road enthusiasts and daily drivers alike.

Performance & Sound

With this suspension system, you'll experience improved ground clearance, better approach and departure angles, and enhanced off-road traction. The upgraded rotors and drilled/slotted design contribute to more effective braking, giving you confidence in demanding conditions. While primarily focused on off-road performance, the system also offers a more aggressive stance and improved handling on paved roads. The installation results in a noticeable increase in vehicle height, allowing for larger tires that further boost off-road capability and visual appeal.

Installation & Fitment

The Fabtech 6" Performance System is designed as a bolt-on upgrade, making installation straightforward for experienced DIY enthusiasts or professional installers. The kit utilizes existing factory mounting points and requires no cutting or drilling in most cases. Proper alignment and suspension tuning are recommended after installation to ensure optimal handling and tire wear. The system is engineered to operate within the factory steering geometry, preserving the vehicle's original handling characteristics while providing increased lift and off-road capability.
