STAGE OPTIONS
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 our Pro Forge 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.
Stage 3
Stage 3 includes a panhard bar as well as sway bar links. Upgrading to stage 3 will help re-center your vehicle's axle and reduce body roll after an added lift. Our panhard bar and sway bar links are stronger and more reliable than stock components.
Stage 4
Stage 4 includes rear adjustable lower trailing arms for added strength and durability over stock arms while also allowing for adjustability and fine-tuning to accommodate an added lift.
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.
