A titre d'info, extrait du site de Rocky-Road qui pourtant vend aussi des kits jumelles inversées :
Some might ask why would the 4"er be better than the latest passing fad.... the shackle reverse??? There are several reasons. Clearance is one. You install a lift to increase clearance on your vehicle. Shackle reverse towers (some folks call them "fangs") hang down and dramatically reduce approach angles. Also, with the shackle trailing in back as with S/R kits, they poke down several inches below the original spring perches and really reduce under frame clearance. 31" tires do not fit on S/R kits without severe rubbing and tire damage. Further, there is the issue of stability. 'Brake dive' is a common problem with shackle reversal in emergency braking which does not occur in non-Shackle Reversed lifts. This is why the manufacturer put the shackles on the front of your vehicle to begin with. If all it took for a smooth ride was to put the shackles in back, Suzuki would have made them this way from the factory (not to mention Jeep with the Wrangler, and Toyota with the Landcruiser). There is a reason the shackles are up front, and it is a safety and stability issue.
Another concern, legality. In places throughout North America and around the world, it is illegal to change the configuration of your suspension as with the shackle reversal lifts. Retailers of shackle reverse systems won't tell you they're selling an illegal suspension, or may flat out deny it. Ultimately, you are responsible for what goes on your rig. The 4"er lifts your vehicle, yet keeps the configuration in stock form with the shackles up front to comply with applicable regulations. Again, its a safety issue, the 4"er is legal, shackle reverse kits may not be.
Finally, your 4"er will give as good or a better ride as any shackle reverse kit on the market. This is due to the top quality Deaver springs we use and the super plush Doetsch Tech shock.... not restickered no-name junk. AND, the 4"er will give you better articulation by simple virtue of repositioned shock mounts for long travel shocks. Kit should fit most 31" tires, check fitment before tire purchase though. OME springs may only fit up to 30" tires.
