Air Lift 5000 Ultm Rear Air Spring Kit For 2011-2017 Silverado, Sierra - 88339

Description

LoadLifter 5000 Ultimate™ Rear Air Spring Kit (88339) by Air Lift®. With Internal Jounce Bumper. Set of two adjustable secondary air helper springs designed to add up to 5,000 pounds of leveling capacity for vehicles with leaf springs. Spring add ride comfort and restores proper handling and safety to 1-ton pickups, motor homes. Air pressure in the springs can be manually adjusted between 5 and 100 psi. Working with your existing suspension, air springs increase your safety and comfort when towing and hauling heavy loads.

LoadLifter 5000 Ultimate™ works with your vehicle’s leaf springs to provide up to 5,000 lbs. of load leveling capacity and keeps the vehicle riding stable, level and comfortable whether loaded or unloaded. The closed-cell urethane foam jounce bumper inside the air spring provides a cushion of air that absorbs shock, eliminates harsh jarring on rough roads and protects vehicles carrying heavy loads. Never bottom out again with the Ultimate™! LoadLifter 5000 Ultimate™ air springs are maintenance free! Safely run with zero air pressure because of the internal jounce bumper. Replaces factory jounce bumper that is sometimes removed when adding air springs.

Air springs are built like a tire and are reinforced by durable 2-ply fabric for maximum strength. Exclusive upper and lower roll plates are included which protect the springs from sharp edges, such as brackets or the frame and help increase load capacity up to 10%.

The suspension of any pickup, van, or mobile home that’s weighed down by heavy cargo, permanently affixed equipment, or a trailer is compromised because the rear springs are crushed down to a height they cannot recover from. Ride quality is reduced, and the front of your vehicle points upward. A rear end that is weighed down literally lifts weight off your front wheels, reducing the amount of traction you have for steering and reducing grip the tires have on the road when you need it in fast braking. After enough time, weighed-down springs sag permanently and the effect becomes even worse.

The LoadLifter 5000™ Air Springs kit is Air Lift’s most powerful set of secondary assist air springs for large vehicles with leaf springs that typically transport more weight. Mount this set of air bags between one end of your leaf spring and the vehicle frame on each side, hook up the easy-connect air lines, then inflate manually as needed. Fully pressurized, both helper air springs can raise up to 5,000 pounds back to proper ride height – taking extra stress off leaf springs and ensuring that a stable, comfortable ride returns. Once your vehicle is back up to a level ride height, you’ll notice headlights and bright lights now stay at the correct aim – illuminating the road ahead instead of tree tops in the distance. Air Lift proudly produces the LoadLifter 5000™ Air Springs kit in the United States, and backs all components with a limited lifetime warranty against failure due to manufacturing defects.

Founded in 1949 in Lansing, Michigan, Air Lift® pioneered the first rubber air bladder that fit inside coil springs to give pickups and other transport vehicles greater load-leveling and ride-stabilizing abilities. These found wide acceptance on commercial vehicles and were soon adopted throughout NASCAR and other professional stock car racing series after assisting many drivers to achieve victorious finishes. Over the decades, Air Lift has continued to pioneer innovative developments with air spring helpers and stand-alone air springs for mobile homes, ambulances, and heavy trucks. During the 1990s, the company was on the cutting edge – developing high-performance air springs and complete air suspension systems that allowed extreme lowering, stunts, and higher levels of handling during aggressive driving. Today, Air Lift is ISO 9001:2008 certified for best business practices, manufacturing, and customer satisfaction and their range of high-quality products is widely respected throughout the industry.

Quality and safety are undoubtedly necessary in a suspension system and GE Engineer Claude Pemberton and Oldsmobile Toronado developer Don Perkins recognized this was essential in a car’s suspension system so they took it upon themselves in 1949 to correct the then problem of sagging springs. Hence the creation of the inimitable Air Lift Company and the start of a remarkable history in innovation.

Recognizing the need for a product in the marketplace is a key to success and Air Lift certainly has done that throughout the years. With the advent of the stock car boom in the 50’s and 60’s came the need to develop a product that would improve handling and traction in the difficult situations racing provided and so Air Lift‘s team went on to do just that and they are still producing products for the competition arena today.

Car innovation and demand for styles are continually evolving and the success of the pickup trucks and SUVs are prime examples of this and, of course, there came with this the need for suspension systems that would support things like towing and hauling. And Air Lift, being the forward thinking company they are, went on to develop primo air springs that allowed you to level your vehicle and thus tow safely,

Fast forward to the late 90s and once again Air Lift recognized the need for a suspension system that would lower custom vehicles; hence, the creation of the Easy Street Division of Air Lift that not only afforded a lower stance but also could be raised when it was necessary to clear an obstacle. The success of full air suspension in mini-trucks offered Air Lift yet another opportunity to introduce a product that was second to none with compressor system technology, air springs and air struts.

The Easy Street name has been changed to Air Lift Performance but nothing has changed about the company’s determination to give their customers a product that meets their expectations in handling performance, providing a lowered stance and the piece de resistance, the ability to raise and lower the car with the push of a button.

Take a look at the Performance Series Air Suspension from Air Lift Performance and you will find a product that can be adjusted with the touch of a button and twist of a knob that lets you drive your car on the road or on the track with an eye catching stance. The system is, of course, a Bolt on OEM Replacement, with most kits offering up to three inches of threaded adjustability and monotube shock internals that run cooler, are more sensitive and weigh less than twin tube shocks. The easily tuned dampers offer thirty levels of adjustment so you are certain to find a setting that meets your expectations and adjustable camber plates that help you achieve maximum chassis performance.

True to its heritage of innovation Air Lift has introduced their all new 3H/3P Height and Pressure air management system that employs both height and pressure sensors to afford the most ingenious air suspension control to date. Whatever your needs Air Lift Performance is certain to provide you with a product that will meet your expectations.
