$1,299.00

Ride Height - 5-6"

1973-87 Dropmember Level 2 Front Coilover

The Porterbuilt Version 7 Dropmember sets the standard of quality and precision in the C10 suspension market. The Version 7 Dropmember is engineered as a modular, bolt-in unit that requires absolutely no welding or fabrication. The Level 2 Touring will set the bottom of the cab approximately 5-6" off the ground at ride height, while providing improved suspension geometry and handling.

Advantages

  • Revised suspension geometry for improved performance and ride quality
  • Rack and pinion steering for increased steering response
  • Proper wheel center-line placement (sets the wheel center-line in the middle of the wheel well opening for a more balanced look)
  • Narrowed trac-width (Level 2 narrows the trac-width approx. 1.25” per side)
  • Added ground clearance over factory components
