When you've been looking for a way to level out your rig, swapping out your own jeep cherokee xj shackles is definitely one of the easiest ways in order to get it done. Let's be truthful, the XJ is a legend for the reason, but the particular factory rear suspension wasn't exactly constructed to last forever. After a few of decades associated with hauling gear, striking trails, or simply daily driving, those rear leaf springs tend to get a bit tired. A person end up with this classic "XJ sag" where the back again end appears to be it's dragging, and that's exactly where a brand new set of shackles is necessary.
Many people start looking directly into shackles for one of two reasons: they either need a small extra height to clear bigger tires, or they're looking to fix the stance of a Jeep that's sitting reduced than it will. It's a relatively basic piece of hardware—just two metal plates and a few bolts—but this makes a massive distinction in how your own Cherokee sits and moves.
Why Shackles Really are a Huge Deal for XJs
The leaf spring setup around the Cherokee is fairly straightforward, but the particular shackles would be the pivot point that lets the whole issue breathe. When you're driving over bumps or flexing out on a trail, the leaf spring has to change its length since it flattens out. The shackle is exactly what allows that movement. In case your stock ones are rusted strong or the bushings possess changed into dust, your ride quality is usually going to be absolute garbage.
Upgrading your jeep cherokee xj shackles isn't simply about the raise, though that's the main draw. It's also about improving the "droop" of your own suspension. A lengthier shackle gives the leaf spring more area to move, which could actually help your tires stay on the floor when you're navigating uneven surfaces. It's one associated with those "bang for the buck" mods that truly pays off the first time a person head off-road.
Understanding the Raise Math
A single thing that vacations up a lot of people is how much lift they're actually getting. It's easy to look at a shackle which is two inches more than stock and assume you're getting two inches of lift. Unfortunately, the particular math doesn't work quite like that will. Because the shackle is usually only mounted on one particular end of the leaf spring, you usually get about half the particular height of the additional length.
So, if a person buy a shackle that's two inches longer than your factory one, you're looking at regarding an inch associated with actual lift on the bumper. If you're trying to gain a complete two inches of height, you're should retain a fairly long shackle. Simply keep that within mind when you're shopping around so that you don't end upward disappointed when the particular Jeep doesn't sit down as high since you expected.
The various Styles You'll Find
When you start searching for jeep cherokee xj shackles , you'll see they aren't all just straight bits of steel. You've got a few different designs to select from, and they will each have their own advantages and disadvantages.
Straight Shackles
These are the most typical and usually probably the most affordable. They're exactly what they sound like—straight pieces of heavy duty steel. They work perfect for basic comes, but on a good XJ, you have to be cautious about the length. If they're too much time, they can actually hit the back again of the "shackle box" (the wallet in the frame where they mount) once the suspension compresses.
Boomerang Shackles
These are a favorite in the XJ community. They have a slight "V" shape to them. The reason regarding this isn't just for looks; the curve allows the shackle to cover around the framework or the fender mounts without bottoming out. This provides a person more travel and prevents that annoying "clunk" you get when a straight shackle hits the body from the Jeep. When you're planning on doing any severe wheeling, boomerangs are usually usually the method to go.
Greaseable vs. Non-Greaseable
Do your favor and get greaseable shackles. These types of possess a small Zerk fitting on typically the bolt that allows you pump oil into the bushing. XJs are well known for squeaky back ends, and generally, it's those dried out leaf spring bushing complaining. Being capable to hit these a grease gun every time you change your oil can keep your Jeep quiet and ensure the bushings don't wear out prematurely.
The Reality associated with the Installation
I'm going to become real with you—installing jeep cherokee xj shackles can either be a thirty-minute job or a three-day headache. It all depends upon one thing: corrosion.
The bolts that keep the shackles to the frame as well as the leaf springs have a tendency to seize inside the particular metal sleeves of the bushings. When you live within the rust belt, you should probably begin spraying those bolts with PB Blaster or Liquid Wrench every day for a week before you decide to even touch a wrench.
A single of the most common issues is definitely the "welded nut" inside the framework. If you're unfortunate which nut pauses loose while you're wanting to back out there the bolt, you're in for an enjoyable afternoon of cutting holes in your own floorboard or your frame to get a wrench onto it. Usually make use of plenty of heat from the torch in case the bolt seems like it's combating you. It's better to melt a bushing you're replacing anyhow than to breeze a bolt or even break a weld within the frame.
Tuning Your Pinion Angle
Something many people forget regarding when they throw on a set associated with extended jeep cherokee xj shackles is the pinion angle. When a person lift the back of the leaf spring, it revolves the axle casing slightly. This shifts the angle of your rear driveshaft.
If a person only go upward an inch or even so, you probably won't notice everything. But if you're putting these shackles upon top of an existing lift kit, you might start feeling some vibrations through the particular seat of your own pants. To describe it in the driveshaft going on about the particular new angle. You might need to install some small degree shims between the leaf package as well as the axle to tilt the pinion returning to where it needs to be. It sounds complicated, yet it's really just a matter of making sure everything is definitely arranged so your U-joints don't use out in a month.
Selecting the Right Bushings
Most auto aftermarket shackles come along with polyurethane bushings. Poly is great because it's much tougher as opposed to the way the factory rubber and it won't rot away as time passes. However, it is definitely stiffer. This indicates you might sense a bit more of the street than you do before.
The trade-off is worth it for almost all people because poly bushings provide a much more stable feel. Your Jeep won't feel quite because "wavy" in the particular back when you're taking corners. Just make sure you employ the specific grease that is included with them (usually that will sticky white stuff) or they will certainly squeak loud sufficient to drive you crazy.
Final Thoughts on the Update
At the particular end of the day, upgrading your own jeep cherokee xj shackles is one of these essential mods with regard to any XJ proprietor. Whether you're trying to fit 31s without rubbing or even you're just fed up with your Jeep resembling it's carrying a lot of bricks in the back, it's a great move.
It's an inexpensive method to get the little extra distance and transform your suspension's ability to bend. Just go directly into the project understanding that those older factory bolts are going to put up a fight. Have your own penetrating oil prepared, maybe borrow the friend's torch, and take your time. Once individuals new shackles are usually in and you also notice that improved position, you'll be glad you did it. Your XJ may look better, trail better, and—if you went using the greaseable ones—it'll oftimes be a whole lot quieter, too.
