The Level 2 system adds our very popular STRONGARM™ tubular control arms. This is a great way to take your truck and give it road gripping handling. The front CoolRide® features upper and lower STRONGARMS® that provide a simple bolt-on to fix those factory units. A 4-Link AirBAR® will position the rear more precisely and eliminate the flexing and instability of the leafspring rear. The 5 gallon dual compressor RidePro®e2 compressor system provides 4 way digital control. It allows 3 system air pressure presets to provide accurate adjustments with the touch of just one button.
