Description: HSW has once again upped the ante on the competition. This time with the ‘Sudden Impact’ line of nitrous kits! Beginning with the highest quality stainless steel and aluminum blocks, each piece is precisely CNC machined to the strictest tolerances. Not only does this produce the finest looking components, but it also ensures that each component performs consistently and at the highest level of performance available. This is not a universal type kit that the competition passes off as vehicle specific. Each system is custom tailored to fit a specific vehicle platform to provide a professional, neat and secure installation.
