Improve your GM 1500's look and ride quality with the Dirt King 2.0 IFP Series coilovers. They come preset with 2.5" of lift to level your vehicle and include a spanner wrench for easy preload adjustments, especially useful when installing aftermarket bumpers or a winch. Although these shocks don't match the full performance of the Dirt King 2.5 DCA coilovers, they substantially outperform OE shocks by offering a smoother ride over rough terrains such as washboards and potholes. In addition they provide increased wheel travel to allow for higher articulation and improved damping on large dips.


  • Increased suspension travel
  • Vehicle specific valving providing optimal ride comfort
  • Aluminum body for cooler operation and corrosion resistance
  • Direct bolt-on replacement that uses factory shock mounting location
  • Maxima custom oil blend. The proprietary light viscosity semi-synthetic oil blend is low friction and extremely resistant to high operating temperatures
  • Cold wound, high-tensile alloy steel coil springs that retain consistent rate and ride height
  • Completely rebuildable and serviceable. All tools and replacement parts can be purchased from Dirt King
  • All Dirt King Shocks are backed by a comprehensive one year warranty


  • 2" hard-anodized 6061 aluminum bodies
  • Internal floating piston
  • Induction-hardened 5/8" shafts
  • Provides up to 3.5” of lift | Trail Boss/ AT4 provides up to 1.5 of lift
  • *Note: Shocks must be paired with aftermarket UCAs. We do not recommend lifting the vehicle more than 3". Excessive preload will reduce the ride quality.
