Leaf Spring

 Shop Leaf Spring




One of the benefits you get from owning a truck or SUV is the vehicle's enhanced towing capacity. This capacity is mostly backed up by an arc-shaped spring steel device called the leaf spring. The leaf spring's length, which usually spans across your vehicle's rear wheels, allows weight to be evenly distributed over the chassis. So if your vehicle's towing a heavily-loaded trailer, the leaf spring keeps the trailer from swaying our bouncing too much. With leaf springs in your vehicle's suspension system, you can safely and easily use your vehicle for towing. Your vehicle may contain more than one leaf spring, depending on how much weight your vehicle can tow. Once any of these leaf springs give in to corrosion and rust, don't hesitate to get a replacement. Browse through our catalogs at Carparts to see your options; we offer you the best in single-leaf or multi-leaf springs.

  • Installing Leaf Springs the Easy Way 11 January 2013

    Leaf springs are one of the most widely used devices when it comes to vehicle suspension systems. Trucks, trailers, and other heavier vehicles are often outfitted with leaf springs since they are able to distribute the weight of the load over a bigger area of the vehicle's chassis. Coil springs are at a significant disadvantage here since they tend to concentrate the weight of the load into a smaller area, which could result in damage. Installing one is quite easy and should only take an hour or two to finish.

    Needed tools and materials

    1. Leaf springs
    2. Penetrating oil
    3. Ratchet
    4. Sockets
    5. Wrench
    6. Hammer
    7. Jack stands
    8. Floor jack

    Before you start

    The brackets and bolts in leaf spring suspension systems are notoriously hard to remove. Most of the time, folks would try to force a bolt or bracket loose and end up destroying them. A great trick would be to soak them up in penetrating oil at least three days before removing the leaf springs. This will not only make it easier to remove the bolts, but it'll also keep them from getting unnecessarily damaged in the process.

    Loosening the spring brackets

    Set up the vehicle on top of a couple of jack stands and begin loosening the spring brackets. Using a small hammer, lightly knock away any loose material or rust that the penetrating oil has loosened the past couple of days. From here, adjust the supporting height of the rear axle until it pulls the leaf springs up. Once there is no tension on the spring, then it's time to loosen the leaf spring bracket U-bolts and eyelet bolts from the old leaf spring suspension.

    Remove the old and in with the new

    Make sure that the axle is supported properly on the floor jack before you pull out the leaf spring. Some folks might need some help here if they find the leaf spring too heavy. From here, simply fit in the replacement leaf spring and reinstall everything back in reverse order. The same process can be done on the other side of the vehicle.
