Quite frankly the best value vs price.  This Lower Tube Kit is a drop-in and go upgrade with not proprietary parts.  This keep you ruing for years.


  • The Phat Hammer incorporates a 2-piece body design, a stainless steel front for durability and a brass body for extra weight to hit the exhaust valve harder, allowing you to run at lower pressures. The Phat Hammer also includes a 1/4x28 hardened lug w/ nylon set screw to keep it from slipping. We have now added a relief cut in the bottom of the hammer in case you grab a rear grip frame screw that's a bit to long.
  • The Rat Valve (9/16) allows incredible air flow consistency. You'll see tighter groupings on the field and at the chrono. Over the years dozens of valves have come up and gone but no one has put out a better one, So, If it ain't broke!
  • The Shocktech SS IVG is made to fit all threaded body cockers with the original valve style.
  • The Shocktech Cocking Rod is made with an adjustable knob broached for use with a 3/16ths allen key to help in precision timing. The rod can be locked in with the same allen wrench you use to adjust your velocity so it doesn't back out while you play. A very simple yet effective design.
  • The Shocktech Springs designed to make this preform at the top of the game.   Don' t play the spring guessing game, we have done that for you.

NOTE:  Shocktech USA cannot guarantee fitment and or performance in any other manufacture bodies.  Nor can we offer tech advice on how to make it work in your situation do to the amount of variables.  We always recommend using a qualified air smith for installation of any of our products.
