Firestone Work-Rite Front Kit

Description:
Install these microcellular urethane springs above your front axle to stabilize and support your vehicle’’s existing suspension. Unlike many one-spring-fits-all kits on the market, this one can be customized according to the weight of your cargo.

Features:
Improves suspension, handling and loaded ride comfort for trucks that carry snowplow attachments, winches or other heavy, front-mounted equipment
Increases stability and minimizes sway from wind gusts or rough roads
Cuts down on road shock and provides a cushion to soften contact between axle and frame - helps to prevent bottoming out
Reduces suspension fatigue and spring sag
Does not affect your vehicle’’s ride when it has no load
Adjustable - offers spacers that allow you to customize for your typical load weight
Install more spacers to increase truck height and handle heavier loads; install fewer spacers for lighter loads
Made from injection-molded, microcellular urethane that has been engineered specifically for automotive applications
High resistance to repeated compression
These springs retain their shape longer
Less play is introduced into the suspension, giving you more control
Smooth axle-to-spring contact with urethane springs
Low temperature flexibility to -84 F (-63 C) - helps springs work better in cold conditions
Effective resistance to road chemicals - extends life of springs
Requires no air pressure monitoring as air springs do
Installs easily above your front axle
No-drill design uses existing holes in the frame for installation in just 30 - 40 minutes
Saves money
Priced less than air suspension systems - enhanced support at lower cost
Protects your factory suspension from wear and tear - less maintenance required
Includes all parts needed for installation
2 Load-assist springs
1/2" Thick spacers for customizing support
Brackets and mounting hardware
Designed to work with a suspension system that is in good working order
Made in USA
Limited lifetime warranty on springs

Note:
Firestone Work-Rite springs will not increase your vehicle's weight-carrying capacity. Do not exceed the manufacturer's weight limit.

Work-Rite springs reduce the front sagging that can accompany snowplow or grille guard use. Both often cause the front of your vehicle to sag while the rear end rises. This means that the front axle is handling more of the load and more of your truck's weight as well. The lighter weight on the rear axle means that the rear tires make less contact with the road, causing problems with traction, steering and braking. With the springs helping to more evenly distribute the weight, your tires make better contact with the road, and your driving control improves greatly. Your headlights stay pointed straight ahead, rather than downward, so that you can drive safely, and your tires suffer less wear.

One size does not fit all when it comes to the load you carry. This spring kit lets you choose from different spacer combinations during installation to give you customized load support for the weight of the cargo that you typically haul. Using the included spacers, you can adjust the distance between your springs and axle. Closing the gap between your springs and axle offers more immediate support and better maneuverability because the Work-Rite springs respond sooner to the load's weight than springs without spacers.

Use more spacers to close the gap if you usually carry heavy front loads, engaging the Work-Rite springs sooner. Doing this increases the height and improves the handling of your vehicle when it's loaded. Use fewer spacers if your loads are light or if you frequently travel unloaded. Leaving at least a 1/4-inch gap between the springs and your axle allows the existing leaf springs to operate normally when you're unloaded, ensuring a smooth, comfortable ride.

Each helper spring in the kit works independently to support the passenger's or driver's side of your truck, so that when you swerve or turn sharply, the spring compensates to reduce body roll. Because your vehicle handles better with the springs, less turbulence is passed along to the trailer, helping to keep the trailer in line.

Your driving comfort is further enhanced if the trailer does begin to sway (for example, from a gust of wind or a passing big rig), because the movement from the trailer is not transferred to your vehicle. The helper springs also work to make the sway subside more quickly.

Work-Rite Springs Versus the Competition
Work-Rite springs are made of a special polymer that helps them to retain their shape better than rubber (yet still work well in below-freezing conditions). They are less elastic than rubber, meaning that less play is introduced into the suspension than with rubber springs. The firmer Work-Rite springs also resist road chemicals and extreme temperatures better than rubber, so they last longer.
