Leaf Spring

We have 1,668 Items for Leaf Spring In-stock.

Enhance your ride's towing and loading capacity without the risk of bottoming out by replacing a worn Leaf Spring. Also known as a semi-elliptical spring, this component is designed to support your vehicle's weight while keeping your ride as level as possible. This spring also provides incredible support for your suspension system. Each time you encounter road irregularities, this spring flexes and relaxes to allow your suspension to adapt to the changing road conditions. Another function of this spring is that it keeps your vehicle from sagging when carrying heavy loads. For these reasons, most towing and cargo trucks are equipped with a couple of leaf springs in their chassis. The secret behind this spring's power and durability lies in its design. You see, instead of using lightweight metal, leaf springs come with at least one heavy-duty steel plate that's bent into an arch. To further strengthen this assembly, most leaf springs are also powdercoated or zinc-plated for rust resistance. Being extremely hardwearing helps this spring carry out its functions for a long time. Unfortunately, frequent overloading will eventually take its toll on this spring. When this spring becomes damaged, you'll notice it right away. Your suspension's performance will slip, and as a result, you'll have a harder time maneuvering your ride safely. That's why if you have a busted Leaf Spring in your ride, make it a point to replace this spring immediately.

Things to Consider When Buying Leaf Springs

Lousy suspension can lead to a bumpy ride and a banged up vehicle. Furthermore, it can also be very problematic when you're towing heavy cargo, which may sway and bounce as you cruise along. Fortunately, our ancestors passed on to us a revolutionary invention to help us deal with such problems: the leaf spring. This suspension component helps in stabilizing your vehicle and in providing excellent suspension for your tow vehicle. Leaf springs come in different varieties, so it's best that you know what you're dealing with before buying a replacement leaf spring.

Types of Leaf Springs

Monoleaf Springs

Otherwise known as single-leaf springs, monoleaf springs are made with only one plate of spring steel. You can identify this type of leaf spring by looking at its design; it's usually thick in the middle then thins out toward the end. This component boosts suspension performance but doesn't really offer much strength when dealing with towed vehicles.

Multileaf Springs

Now these are the bad boys we recommend for hauling heavy loads. Multileaf springs consist of many springs of varying length. These springs are stacked on top of each other and provide ample support and strength for managing hefty trailers.

Leaf Spring Ends

Double-eye Leaf Springs

These springs have top plates that have their ends curved into a circle. These ends make two holes that you can hook up to your trailer's bottom frame. These are recommended only for medium utility duty applications (less than 7,000 lbs).

Open-eye Leaf Springs

These springs only have one "eye" or open hole, with its other side coming in the form of either a hook end or a flat end. This type of spring is highly beneficial because it requires you to maintain only one mounting point, and it can withstand light to heavy duty loads.

Spring into Action: Replace Busted Leaf Springs

Your suspension system deserves a round of applause for keeping your ride comfy through twists and turns, bumps and humps. However, your trusty suspension components won't last forever, and they'll eventually call for replacement units. This sad fact applies to all auto components, including your leaf springs. Lucky for you, replacing busted leaf springs shouldn't take up much of your time. Just follow these simple steps, and you'll have your suspension back in fighting form.

Difficulty Level: Easy

What you'll need:

  • Safety Glasses
  • Latex Gloves
  • Floor Jack
  • Pliers
  • Jack Stand
  • Pry Bar

Step 1: In order to avoid any unwanted mishaps, be sure to wear safety goggles and latex gloves before beginning your DIY job.

Step 2: See to it that your vehicle is parked on a level surface to ensure that it doesn't roll when it is raised.

Step 3: Place your floor jack underneath the frame pitch weld and use the jack to lift the rear of your ride to the point where the axle assembly is hanging freely.

Step 4: At this point, you'll want to secure the jack using jack stands, which will provide you with utmost safety while you're making your repairs.

Step 5: Remove the lower bolt from the shock absorber.

Step 6: Lower the axle to relieve spring tension, then remove the U-bolts and the spring retainer bracket.

Step 7: Loosen the rear shackle bolts then remove the leaf spring's front and rear eye bolts. Be sure to the support the leaf spring using the jack stand before removing the bolts.

Step 8: Remove your busted leaf spring from the vehicle.

Step 9: Position the front bushing of the new spring into the front mounting bracket and install the front eye bolt and nut. See to it that the bolt head is facing the center of the vehicle.

Step 10: Do the same for the rear shackle and loosely install the rear eye bolt and nut.

Step 11: Place the leaf spring center bolt into the axle pad hole by raising or lowering the axle.

Step 12: Install the U-bolts and retainer bracket but do not tighten the U-bolt nuts. Connect the lower shock mount to the axle bracket.

Step 13: Repeat steps 4-12 on the opposite side.

Step 14: Lower the vehicle to the ground and then tighten all the bolts.

Step 15: Test drive your ride and see if the leaf spring is working perfectly.
