YJ spring conversionFlex and ride comfort... As offroaders, we just can't get enough of this stuff. What to do... what to do.

Easy answer? Swap out those stiff springs on your Jeep CJ to some nice soft YJ Wrangler springs. No doubt you've read about this swap somewhere thru the years, our new kit gives you an easy way to bolt on more a MUCH more comfortable suspension without any adverse effects at all. Our kit converts the front to YJ springs, in your rear, the YJ springs will bolt right up.

These are 35" tires and the flex is insane! Still drives nice and stable at highway speeds.

You want SICK flex and EXCELLENT ride quality.... chuck 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. We also carry 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) and Old Man Emu Wrangler springs for those that want the best riding lifted Wrangler spring on the planet!

Beyond flex though, ride quality is dramatically improved with the Wrangler spring conversion. Stock springs can and oftimes do ride a bit like an old military pickup truck. Wrangler springs though, they will make your old Jeep ride like a modern SUV.

Some folks have asked us about shackle reverse kits when converting to the Wrangler springs....

We did used to carry such a system. However, we found that Jeep (along with Toyota and other vehicle manufacturers) put the shackles in the front in short-wheelbase 4WD's for a reason.... SAFETY.

Running shackles in the rear on a short-wheelbase vehicle like a Jeep CJ makes the vehicle highly unstable under hard braking (which is usually when you need your brakes the most). Further, shackles reversals on the CJ create axle hop under braking. After seeing a Jeep coming off of Lion's Back in Moab with his front axle hopping and a resultant total loss of control, we swore off shackle reversals forever.

Putting the shackles in the rear may seem like a cool way to go and you may read about smoother ride quality, but the bottom-line is that the vehicle becomes unstable and the ride quality of just using Wrangler springs alone with the shackles up front as they should be is as much comfort as any Jeeper could ever ask for.

SO in a nutshell, the Rocky Road Wrangler spring conversion kit is super simple to install, comes with bushings (most of these conversion kits do not), and is a greaseable suspension item. Comes with hardware and the same kit works for all CJ 5's, CJ6's, CJ7's, and CJ8's.

cj with Wrangler springsRocky Road also sells Wrangler springs, both stock and Old Man Emu lifted, to work on your CJ after the conversion.

This is so no-brainer... why wouldn't you get one!?!? 

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!

Rocky Road Engineered Jeep Shocks

We tested other brands of shocks for many years and were often very unhappy with the ride quality. We tried all the big 'name' shocks, Edelbrocks, Bilsteins, ProComp, Skyjacker, etc. All the same, all too stiff for the Jeep. So, we worked with doetsch tec to engineer a shock that stands head and shoulders above the rest for ride quality.

These shocks are absolutely perfect for folks who want a great on and off-road shock, but don't want to spend over $200 buying them (and doesn't want to deal with their hassles). These shocks are valved lightly for a very smooth highway ride.

Are you looking at shocks from companies that produce lift kits for full-size pickup trucks? If so, those shocks that are desgined to work on 10cylinder diesel pickup truck lift are the exact same shocks that the lift company is supplying for your Jeep. Does that sound right to you? How do you think a shock that is engineered to accomodate a 6-7,000 truck are going to ride on your vehicle weighing 1/3 that amount? Common sense will give you the answer to that question.

We engineered these shocks specifically for their ability to provide great on and off road performance for Jeep.... not full size pickup trucks.... Jeeps. We size them perfectly to run with all our lifts and carry them in most every length for any application.


Custom Hand-Built Shock Option...

Nitro Monotube, hand built

The standard shocks included in this kit are manufactured by Doetsch Suspension Systems. These shocks are an excellent value and have the following features:
  • Twin tube design
  • Generic Valving that is excellent for the Jeep
  • 1 3/8" piston
  • Closed cell foam
  • Baked enamel finish

You can also upgrade to nitrogen charged shocks. The nitrogen gas and larger bore increase control and will react instantly to changing conditions. These shocks have the following features:

  • Hand Built
  • Valved specifically for your vehicle
  • Mono tube design
  • Large bore
  • Powder coat finish

PLEASE NOTE: We will need to contact you and speak to you about the specifics of your Jeep, lift, shock mounting. These shocks are hand-built and tuned specifically for your Jeep, so we will need additional into after checkout with online orders.
