The first kits are stock replacement. The pocketed rear shock mounts will net a little bit more rear suspension travel but the main focus of this kit is major strength upgrade. For those who really beat on their RZR XP. After racing the KOH race this year on stock arms we identified a need for a beefier set of control arms. All joints are FK heavy duty units and the kit can be built to upsize the bolts on all mounting points as well. The kit will accomodate stock shocks for those who choose to upgrade in stages or we can supply custom tuned fully adjustable Elka shocks.
