Spring Work’s Blog

Spring Works offers Firestone air helper springs (air bags) that fit a majority of light trucks, SUV’s, motorhomes and vans. These durable air springs allow you to maximize your vehicles carrying capacity through the use of air pressure. Making your vehicles suspension adjustable for various road and load conditions.

Firestone air helper springs will:
Keep the vehicle front end down, Level off-center loads (front-to-rear and side-to-side leveling), Reduce suspension fatigue, Increase vehicle stability and comfort, Carry loads ranging from *1000 -5000 lbs. Go here.

All Eibach products are not only developed and manufactured with a great deal of experience, but also with heart. The requirements of Motor Sports are a constant challenge to us. Approval and the goodwill of our customers - from the manufacturer of the vehicle to the individual automobile fan - are comforting applause to us. Go here.

Rubber is the sap of trees found mostly in tropical climates. The sap is altered by mixtures of carbon (why it’s black) and mineral oils and various fillers. Polyurethane is completely chemical or man-made. Because rubber is a biodegradable product it  is affected by ozone and will over time dry rot and degrade, while urethane will keep going and going. Urethane bushings will increase the performance handling characteristics of your vehicle. Urethane is a firmer material then rubber. It is more responsive then rubber. OE (Original Equipment) rubber bushings are usually softer and provide comfortable ride characteristics. Most OE bushings are rubber. Each type of bushing is suited well for the specific handling the user is attempting to achieve. Go Here.

Polyurethane is a term used to describe a wide ranging family of elastomers (any compound exhibiting the characteristics of natural rubber; stretchy and elastic.). Poly meaning “many” and “urethane” the classification of the chemical structure. Polyurethane or urethane for short, is used as a solid cast material (bushings). Polyurethane can be as soft as a rubber band or as hard as plastic.

We suggest that whenever the springs are removed and replaced, you should change your u-bolts at that time. It is a relatively inexpensive insurance policy to keep your vehicle is safe

Variblee rate springs defelct at different amounts per inch. An example would be: 200 lbs. = 1 inch deflection, 600 lbs. = 2 inch deflection, 1000 lbs. = 3 inch deflection, and so on. Varible coils have a soft initial spring rate and a much firmer spring rate to handle more weight, decrease sway, and improve handling. Go Here.

Constant rate springs defelct the same amount each inch. An example would be: 200 lbs. = 1 inch deflection, 400 lbs. = 2 inch deflection, 600 lbs. = 3 inch deflection, and so on. Constant rate coils have will restore your vehicle to its original height and ride.

Rearching is a process of re-curving each leaf spring to original or custom specifications. Once the springs are individually rearched they are then heat set. Heat setting is done by heating the spring to a specific tempature for a specific time.

The most common method of leaf spring inspection is checking the vehicle ride height. Measure! Don’t rely on eyesight alone! This method will only catch the extreme cases of spring sag or leaning. In addition to checking ride height, look for these signs, which also indicate the leaf spring requires attention:Examine each spring for stress cracks, missing leafs, or shiny spots between leafs.

There is no standard life expectancy for leaf springs. In general, leaf springs on smaller lighter weight vehicles tend to last longer then leaf springs on heavier full-sized vehicles applications. To determine when coil springs need to be replaced have the springs inspected and the vehicle ride height checked by a trained professional.
