CJ Spring Over Axle Lift Kit

Why a Jeep CJ Spring Over Axle Lift Kit? Because there is no better system on the market in terms of suspension flex and cost balance… while still keeping your Jeep very streetable in a safe manner.

You can spend thousands on a coil-over conversion setup, but they won’t get any more flex than a Rocky Road SOA equipped CJ…. not to mention the thousand or so you’ll spend on the specialized installation required for those kits. Our system is also bolton and requires no cutting. It is completely reversible if you have need to go back to stock, or transferable if you want to move it from one Jeep to another. Try and do that with one of those super involved coilover weldon systems. For those who just love to weld though, our bolton system can be welded in place as well.

While even the most seasoned wheeler will enjoy the benefits of our SOA system, its installation is certainly novice friendly. Never wrenched a Jeep before? Here’s your chance to get started. Our CJ Spring Over Axle Lift Kit makes it so easy that you can begin installation in the morning and be wheeling by that afternoon!

Jeep CJ Spring Over Suspension, Tire Size

Our CJ SOA kit fits most 35″ tires, though 33’s are common and its easy to step up even larger! Add in our optional shackles and you can go ever larger…. all bolton, all budget friendly.

SOA lifts simply offer the best articulation of any leaf-spring lift on the market due to the extra leverage which deflects the spring packs and provides for more twist. Its a great way to go and in fact, Toyota pickups, Jeep Cherokees, and most 4WD pickups come with their springs SOA from the factory!

We know you will find our kit extremely well thought out, incredibly beefy, designed for serious offroading, and the demands it puts upon a vehicle. Our system also includes components that our competition’s kits neglect to include that make this a safe system for driving on the highway as well.

CJ SOA kit

How does the Rocky Road CJ Spring Over Axle Lift Kit lift stacks up against other suspension lift systems that only use lifted leaf springs??? Extremely well. There are a couple reasons why.

• Clearance… You install a lift to increase clearance on your vehicle. Lifted spring kits do move the vehicle up, but they also leave alot of junk under your axles which reduces clearance. Our SOA system only sits about 1″ below the axle housing. Typical lifted spring kits with the springs under the axles will hang down about 2.5″. That one and a half inches may not sound like much, but its more clearance difference than you’ll see between running 33″ or 35″ tires! Bottom line, SOA lifts put everything above the axle for max clearance!
• Flex… Most offroaders today want the maximum flex they can acheive, while not making the vehicle unstable for highway driving. An SOA is a great way to accomplish this balancing act. The extra leverage by placing spring on tops of the axles gets you the same kind of flex as extreme coilover or 1/4 elliptic systems. Main difference is that you can still drive your CJ safely at 75MPH on the highway, and those extremeguys cannot.

With our kit you can drive your rig to Moab, Rubicon, Tellico, or your local playground safely, conquer all the hardest trails with MAD flex, then drive the same rig to work the next day.

Why the Rocky Road Jeep CJ SOA Lift is the Best

Looking at other CJ Spring Over Axle kits on the market? Let us explain why our kit is so far superior and what the other kits are missing that is required for a safe and proper installation…. and yes, our kit does cost less even though we provide twice the equipment!

• Start with our spring perches. They are custom built and designed to slip over your front and rear and onto the factory spring pads. The mounting system extremely tough, durable. They insure your axle housing does not suffer damage in the harshest trail conditions. Our spring pads are also fully gusseted, and BY FAR the strongest. They are also easily the safest on the market for you, your passengers, and your Jeep. They self-align for proper castor setup every single time. They do NOT require welding (as other saddle style spring pads require) and are very easy for the novice to install. Our perches provide 5-6″ of lift.
• Another great design feature of the spring perches is their extended length to combat spring wrap. No other spring pad on the market does this. We also provide all necessary hardware and axle mounts for the spring perches. Our spring perches are built extra long to help combat spring wrap! You won’t find any other system on the market that has this degree of engineering on these spring pads.
• Long travel shock mounts. Designed to provide the needed clearance from your shocks to the springs to avoid damage. Also, a great way to provide ample room for long super flexy shocks. Front and rear lower shock mounts are included for maximum shock length which means maximum articulation.

CJ SOA, more and better components…

• Ubolt skidplates. While these are not necessarily mandatory for any lift, we sure feel they serve their purpose. Our custom built spring plates provide rock and trail damage protection thru a unique slide plate protection system. A simple idea which really goes the extra engineering mile.
• To properly correct steering angles, we offer our exclusive Zlink steering system. Other kits? They provide nothing. Lifting a vehicle stretches out steering geometry and causes some peculiar things to happen. Your steering becomes cockeyed, linkage hits springs, etc. Our Zlink puts things back into shape. Kit comes with replaceable tie rod ends easily greased and serviced. An SOA lift without steering correction is just plain dangerous. Rocky Road has you covered.
• Transfer case drop. Some Jeeps are going to have to customize their driveshafts with this heigt of lift. Others seem to get away with the stock driveshafts. Either way, our tcase drop system helps ease the angle of your Ujoints on the driveshafts. Build from solid billet steel. These things are THE BOMB when it comes to strength.
• Taller lifts necessitate longer brake lines. You don’t even want to take the chance of snapping a line on the trail. Thus, longer brake lines front and rear are very important. Do the other kits include them? No. Even the most novice of 4wheelers can understand how dangerous this is. We’ve used many combinations and brands of brake lines over the years and have experienced the best overall result with rubber brake lines. So in our kits, we offer only extended DOT approved rubber brake lines. No vehicle inspector will ever red-flag your brake lines with our system as can happen with the relatively unreliable stainless lines.

CJ Lift Kit, with YJ Conversion

Our SOA kits also have the option of wider spring plates and spring pads for use with a Wrangler spring conversion kit (conversion kit sold separate).

You want flex and ride quality…. toss those old CJ springs and pick up our Wrangler spring conversion system. Your CJ will ride like a modern SUV and flex like a competition rock buggy. If you already have a Wrangler spring conversion on your Jeep, just make sure and pick up our SOA system built for the wider Wrangler springs.

If you don’t have Wrangler springs, our conversion kit is available. We also sell brand spankin new Wrangler springs for those who want factory fresh instead of used. Although, used Wrangler springs if you find them will work well too.

*We highly recommend measuring your drag link to confirm axle width. Narrow track CJs are approximately 43″ from the center of tie rod end to the center of the opposite tie rod end. Wide track axles are approximately 46″ for the same measurement. It is very common for previous owners to have swapped wide track axles into CJs that were originally narrow track vehicles. If you order the incorrect axle width you will be responsible for all costs associated with exchanging the parts.
