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 system makes it so easy that you can begin installation in the morning and be wheeling by that afternoon!
The SOA kit alone should fit most 35" tires. Add in our optional shackles and you can go ever larger.... all bolton, all tight-wad 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.
Joshua Wilson sent us this picture by Facebook showing off his awesome new
suspension flex by combining the Rocky Road Spring Over Axle lift, with
a nice new set of Wrangler springs. This is all bolt-on, highway safe... and legal!

How does the Rocky Road SOA 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 extreme guys cannot.
This picture shows our Scrambler with SOA kit and our Wrangler spring conversion. These are 35" tires and the flex is insane! Still drives nice and stable at highway speeds.

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.
Our SOA kits for 1976 and newer Jeeps also have the option of wider spring plates and spring pads for use with a Wrangler spring conversion kit (conversion kit sold separate... available soon).
You want SICK flex and AWESOME 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 now 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.

Shows passenger's mount, lower U-bolt skidplate, and OTT steering system.
Start with our spring perches (Patent Pending). They are custom built and designed to slip over your front and rear and onto the factory spring pads to make the mounting system extremely tough and durable. We put alot of energy into engineering and fabricating these pads to insure your axle housing does not suffer damage in the harshest trail conditions. Our spring pads are also fully gusseted, BY FAR the strongest, and 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 6.5" of lift. ANother great design feature 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, but 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.
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, so 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.

Reviewing the 100% correct chart above, you may ask yourself what the heck are the other guys even including in their kits? Why are their kits costing so much while at the same time missing so many critical components? Why do those kits even exist on the market? What kind of crazy mixed up world do we live in?
Well... we ask ourselves those same questions and just don't have the answers. The best we can hope for is to inform YOU so you can decide which kit offers the greatest value.
OTT Steering system upgrade. This awesome high steer setup is designed specifically for SOA use. Excellent for use with stock springs, or lifted springs. Pictured to the right with the optional steering shock. OTT Steering systems available for all CJ's 1972 and newer.

Rear Ubolt top plate. Most Jeeps can simply re-use their stock Ubolt plate and flip it topside for their rear SOA system. This helps keep the cost down for most everyone. However, for those that want everything 100% new, we do offer a new Ubolt top plate which replaces the original stock piece for a new heavy duty powdercoated piece.
2" longer shackles. These 2" shackles provide an extra 1" of suspension lift for a full 7.5" lift all together. 3 bolt design for the ultimate in flexy design for articulation junkees.
Rocky Road soft-ride long travel shocks. We feel we have designed the best riding shock we have found on the market today for moderate weight vehicles like our Jeeps. Other shocks are designed for vehicles thousands of lbs heavier (namely, pickup trucks), our engineered shocks are right on the money for a Jeep. Superbly valved for a great ride on road without being mushy offroad. Shocks are $155 for all four with the purchase of a kit, or $46 each if purchased on their own.... OR, the ever-popular Rancho 9000XL Adjustable shocks which allow you to adjust and dial in your shocks for your favorite setting, or change it up depending on the driving and terrain you hit for the day.
Stock height leaf springs. For those of you who have totally worn out springs and are looking for a fresh set, or for those who have a super-duper stiff horrible riding set of springs you are looking to get rid of (BDS owners, you know who you are), we carry brand spankin new replacement springs. Yes, these are the original springs completely new and they will ride awesome on your old CJ. No need to suffer with those brutal stiff lift springs anymore.
Wrangler spring conversion kit. If you are looking for the ultimate in ride quality and suspension flex, converting your stock CJ springs over to Wrangler leaf springs will hit the spot. This kit is super simple to install and will dramatically improve the suspension on your old CJ. If you have ever considered doing this swap, then there is no better time than while you are installing your Rocky Road SOA system. Comes with grease fittings for easy service, bushings, and hardware. We also sell factory fresh Wrangler springs if needed.

Wide-track axle is about 46" from rod end to rod end.... Narrow-track axle is about 43" from rod end to rod end.
Slip Yoke Eliminator (SYE)/ Tailshaft transfer case conversion may be needed for Jeep NP231 transfer case
Front driveshaft may need to be lengthened
Kit for pre 76 CJs is only designed to be simple bolton for D30 front, and D44 rear axles. Other axles may be
used, but some modification may be needed for tight fitting, and welding may be necessary for installation
Kit for post 76 CJs is only designed to be simple bolton for D30 front, AMC20 rear axles.Other axles may be
used, but some modification may be needed for tight fitting, and welding may be necessary for installation
CJ5 kits come with upper front shock mount extensions since the lower mount situates higher (narrow track axles).
1986 CJs also came with an optional factory Dana44 axle. If you have this factory D44, please note this at your time or order to receive the correct axle mounts.
The bottom line is that no other SPOA system on the market comes close to the Rocky Road system for ease of installation, warranty, engineering, and quality. Do it right the first time with Rocky Road.
