Firestone Work-Rite Custom Helper Springs Kit - Rear Axle

2001 GMC Sierra - Firestone Work-Rite Custom Helper Springs Kit - Rear Axle

Install these microcellular urethane springs above your rear axle to stabilize and support your GMC Sierra'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
  • 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 heavy loads; install fewer spacers for light loads
• Made from injection-molded, microcellular urethane that has been engineered specifically for automotive applications
  • High resistance to repeated compression
    • 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 rear 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 the USA
• 2 Year 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 for your vehicle.

Work-Rite springs reduce the rear sagging that accompanies heavy loads or that results from towing hefty trailers. Hauling heavy cargo or pulling a trailer often causes the rear of your vehicle to sag while the front end rises. This means that the rear axle is handling the full weight of the load and more of your truck's weight as well. The lighter weight on the front axle means that the front 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.

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 optional spacers, you can adjust the distance between your springs and axle. Closing the gap between the springs and your 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 haul heavy loads, engaging the Work-Rite springs sooner and increasing the height and improving 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 and still work in below-freezing conditions. They are less elastic than rubber, meaning 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.
