reverse shackles are an arguing point,
the benifits include-
-increased approach angle
- the ability to fit taller shackles (the problem with them on the front is they act like fangs and chew into the ground and although they generally make the sj taller they really decrease the approach angle)

the main disadvantage is from the opinion that they houldn't be for road use,

this is lifted from rockyroads website

SHACKLE REVERSE-- Popular for many years with do-it-yourselfers, and more recently available in kit form. Common with off-road racers running front leaf springs as highspeed impacts are absorbed through the rear of the spring than up front. The shackle reverse is best when NOT used on short wheelbase vehicles like a Samurai. If all it took to get a smooth ride was to put the shackles in back, then anus would have built the Wrangler this way, Toyota with the Landcruiser, Land Rover with the Rover series, and Suzuki with the Samurai. The bottom line is that shackle reversals on short wheelbase vehicles cause strange and potentially dangerous things to happen to your vehicle at highway speeds when you are braking hard. You will NEVER see a shackle reverse on a short wheelbase vehicle from any factory for this reason. In a nutshell, the S/R theoretically designed as a possible way to try to smooth out a rough riding vehicle on mild terrain; which means forest roads, desert driving, scenic, etc; and this theory does work somewhat well with long wheelbase vehicles like pickup trucks, but not with any safety on short wheelbase vehicles.
Some Gotchas with shackle reversals....
Engine swaps kits that use larger oil pans such as the 1.6 get munched on shackle reversals so avoid all shackle reversals (bolt-on or weld-on) if you plan on swapping up to a larger engine.
Be wary of bolton Shackle Reverse kits. They dramatically reduce your approach angle for obstacles. They severely limit your choice of aftermarket front bumpers. And the list goes on for avoiding these type kits. All you'll get is sales pitch, no straight talk on all the ramifications of this lift on your vehicle.
Be aware that in many places across North America, most of Europe, and in many countries around the world, it is illegal to modify the configuration of your vehicle. This means you can lift your vehicle with lifted springs. But using a shackle reverse makes it so your vehicle has an illegal suspension and will not pass annual inspections.
We do NOT recommend any shackle reverse kit to be installed on any highway driven vehicle for safety reasons. For the safety of you and your passengers, shackle reverse kits are FOR OFF ROAD USE ONLY.
Myth... My truck didn't come with the suspension in this configuration so it can't be safe. Offroad racers, fourwheelers, and long wheelbase vehicles have been using shackle reversals for years. Some 4wheelers complain about brake dive and the vehicle handling does often change for the negative. Shackles reversals are okay for OFFROAD USE ONLY. But please do not install them on highway/street driven Samurais!


although i think this is just a slanderous salespitch, on difflock some one said... (in discussing S/R)

Reason why (and its been posted loads of times on here if you search) the ride was awfull and crashy as the shackle was at the wrong angle with stock sprngs.. It also had stablity issues when braking whilst steering as axle moves backwards as it goes up makingthe wheel base shorter just when you need it most.


although of course I've never had any trouble with it, ive passed mot's with it and even discussed it with my iinsurer so the part about it being illegal is wrong, personnaly i think it is a great piece of kit, every one seems to have different opinions but im deffinatly for S/R

here is a link to difflocks take on S/R
