Essential Components of a Lifted Truck

A "lifted" truck isn’t just about bigger tires. It involves a system of integrated components designed to raise the vehicle’s body and/or suspension, accommodate larger wheels, and maintain proper driving dynamics.

• Lift Kits:
  • Body Lifts: Raise the truck body from the frame using spacers. They are less expensive, don’t change suspension geometry, but offer limited clearance gains and can expose the frame.
  • Suspension Lifts: Replace or modify suspension components (shocks, springs, control arms, leaf springs, etc.) to increase ride height. These are more complex and expensive but provide true ground clearance and better off-road performance. They often require additional modifications like longer brake lines or driveshafts.
• Larger Tires and Wheels: A primary reason for lifting is to fit bigger, more aggressive tires. These improve traction off-road but can impact fuel economy, braking, and speedometer accuracy. Aftermarket wheels are often chosen for their strength, offset, and aesthetic appeal.
• Steering and Driveline Modifications: Lifting a truck can alter steering angles and driveline geometry. Components like drop pitman arms, extended sway bar links, and potentially longer driveshafts or re-geared differentials may be necessary to correct these angles and prevent premature wear or vibrations.
• Shocks and Suspension: Upgraded shocks are crucial for a good ride quality and damping with a lift. Many quality lift kits come with performance-tuned shocks designed for the increased travel and weight.
