'03 gloss red nasty impulse, matching freak kit, rat factory kit, was board, evil respirator, black otb frame, black nd 15* asa, black nd halo no rise, black system x drop, crossfire 72/45 preset 450 psi tank.
improved efficiency, reduced kick, ability to run at a lower psi
having to install the ram and hammer
the second i put this kit in my imp i could run at 140psi opposed to 180psi. it increased the efficiency allowing me to shoot 400 more shots per fill also improved the consistancy shot to shot over the chrono. the long i use this the better it works. you will not regret this purchase, i suggest this as a first upgrade for any new imp owner.
