Stage Options for F-150

Stage 1

Stage 1 offers a complete suspension kit with all the necessary components to lift your vehicle and fit custom wheels and tires for better off-road performance.

Stage 2

Stage 2 includes Upper Control Arms, which help correct your vehicle's geometry back to OEM specifications when lifted. This helps reduce unnecessary wear and tear over time on your vehicle's other suspension components.

Load Options

Light Load

Light load will allow your vehicle to ride similarly to stock for comfort and with little additional payload support.

Medium Load

Medium load gives you the most versatile driving experience. We almost always recommend medium load for vehicles that are occasionally loaded on the weekends but are driven daily without weight during the week. This gives your vehicle the most comfortable and practical ride for most types of off-roaders.

Heavy Load

Heavy load will allow you to carry extra weight when loaded AT ALL TIMES. We recommend this option only for vehicles that are constantly loaded with the listed minimum additional payload weight all the time. If not, your vehicle will be a stiff and uncomfortable ride.

Extra-Heavy Load

Extra heavy loads require a significant amount of additional weight. We recommend you add up all of the additional gear you will have in your vehicle at all times to make sure it meets the minimum listed additional payload. Contact our customer service before ordering extra heavy load springs.

Never exceed the vehicle manufacturer’s stated Gross Vehicle Mass (GVM). Exceeding the GVM can compromise vehicle safety, performance, and handling, and may void the manufacturer’s warranty. Always consult your vehicle’s owner manual or manufacturer for the correct GVM specifications before loading your vehicle. Use all equipment and accessories responsibly and in compliance with applicable laws and regulations.

Features:

2.5” Monotube Aircraft-Grade Aluminum Construction: The 2.5” extruded monotube body is made from 6061-T6 aircraft-grade lightweight aluminum, offering up to 4x better heat dissipation and 30% weight saving than steel for enhanced durability and cooling efficiency.

Large 57mm Billet Aluminum Piston: The CNC-machined billet aluminum piston offers 60% more surface area than traditional designs, enabling precise valve tuning for exceptional ride comfort and control.

Premium Build Materials: High-pressure (200PSI) nitrogen gas, NOK seals, and Fuchs hydraulic oil contribute to long-lasting durability and high-performance under extreme conditions.

Velocity-Sensitive Design: The monotube damper adjusts seamlessly to changing terrain, providing a plush, smooth ride on highways and responsiveness on rugged trails.

Type 2 Anodized Corrosion Resistant Finish: Military grade anodized corrosion resistant finish withstands harsh weather, mud, and road grime for extended durability and reliability.
