Capacity is engineered to work with specific vehicles displayed below. Can't find your vehicle, or need assistance, please give us a call at or All of the manufacturers that we represent produce leaf springs that are as good as or better quality than OEM springs. Virtually no vehicle manufacturer actually manufactures their own leaf springs.
Like many other truck components, leaf springs are purchased from companies specializing in supplying parts to truck manufacturers. The springs we sell have the same or better quality as OEM springs and many times are purchased from the same manufacturer. Damage from accidents, corrosion, improper installation, incorrect applications, overloading, and custom applications that are not specified under the OEM cross references.
This warranty does not cover loss of freight, loss of profit, equipment, or personal downtime. Any alteration of products will void the warranty. Warranty is void if new u-bolts are not installed when the new leaf spring is installed.
Using existing u-bolts is a common cause for leaf spring breakage and failure. If a leaf spring failure results from a manufacturer defect, contact us at Michigan Truck Spring for support. My wife calls me "Nitro Charger" now.
She's the best! Examine [both the front and rear spring perches] on both sides of vehicle for any damage. If any damage is noted, it must be repaired to "new" factory original condition. The kit comes with all new rear leaf spring bushings original factory parts and the bushings are pre-installed from the Cherokee Connection. This is a super feature of the Cherokee Connection kit, because without the proper tools the bushings are a pain to insert.
Attach the new shackle to the new spring. Do not use power impact or air ratchet to tighten nuts, they are nylon insert locknuts aircraft style and need only be tightened with a wrench by hand. To make installation easier, I measured from perch to perch and matched that distance--spring eye to upper shackle bolt hole--when I tightened the shackle to the spring. If you want, now's the time to compare the new and old springs.
The shackles add a bunch of height, but so do the springs. They're stiffer, have an extra leaf, and each leaf is way longer. Install the new springs. Tighten the bolts to proper factory specifications. Be careful to not over-tighten bolts; damage to shackle or vehicle can result.
Raise the axle until it hits the new springs. With just the right amount of pressure under the axle, the pins should pop into place without too much muscle. In the majority of cases where springs fail, the problem is down to excess weight on the rear suspension system. If the rear of the vehicle sags, it might be due to spring failure, but it could also be due to inadequate springs in need of more leaves. The leaf springs that come with a truck are specifically manufactured to accommodate the weight, size dimensions and load capacity of that particular vehicle.
Therefore, when you replace a set of rear leaf springs, it is crucial to make sure the new pair matches these specifications. That said, you can augment an existing pair of springs if you have a special need to boost the suspension. For example, if you regularly max out the load capacity to haul large and heavy equipment over grueling terrain and long distance routes, it might be in your best interest to augment the springs with extra leaves.
After all, while pre-existing springs are optimized for maximum loads, it is generally assumed that vehicular use of this nature is rare among most drivers. Consequently, a conventional set of leaf springs can wear down more rapidly if the suspension is regularly pushed to the limit. If the driving quality of your truck has slowly declined over the past year, but you have just now traced the problem to your leaf springs, a new pair of leaf springs will indeed improve the vehicle from its recent performance patterns.
The improvement is best described as a "restoration" of the vehicle's original driving capabilities. A used leaf spring is generally interchangeable with a new one as long as both are the exact same size. Therefore, when you replace an old leaf spring with a duplicate, it will restore the performance of the truck to its earlier driving condition.
However, in order to boost the weight limit of the vehicle, you will need to add more leaves. If you do decide to add leaves for hauling purposes, remember that the payload of the axle can never be increased.
If the vehicle is loaded past this limit, the pressure is liable to wear down the axle shafts and wheel bearings. In some cases, overloading can even ruin the transmission and certain engine components. In order to replace a set of leaf springs, a truck must first be raised onto jack stands so the underside components can be accessed.
Then, the wheels must be removed so that the springs can be reached. From there, the old springs can be dislodged and set aside to make way for the replacement springs.
Of course, all of these steps involve more detail than we can go into here. If you read and understand the instructions on how to replace leaf springs, you can do the installation work yourself as long as you have the necessary tools close at hand. The first time you do this kind of installation, the project could take several hours to complete.
You'll want to be sure that you choose the right part, however, so don't hesitate to get in touch with us if you have any questions. There are a number of benefits to replacing your Jeep Cherokee's leaf springs. These products are capable of correcting sagging, leaning and swaying, as well as restoring the original height of your vehicle. Additionally, the product's tip inserts are designed to reduce the effects of friction, prevent loud squeaking sounds from emanating from the spring and eliminate shear point from metal-on-metal contact.
To get started with replacing your Jeep Cherokee's leaf springs, you'll want to ensure you have all the proper equipment to accomplish the task. This includes the leaf springs themselves, an installation kit, sockets, wrenches, jack stands, pry bars and torque wrenches.
We're happy to help point you in the right direction for additional instructions on how to make the best of your new leaf spring investment to optimize your Jeep Cherokee driving experience.
