1963-72 Chevy Pickup Front Dropmember, Level 2 Coilover


The 1963-72 Chevy Pickup Front Dropmember Coilover suspension system is designed to replace the factory cross-member and steering system. It is engineered as a modular bolt-in unit that requires no welding.
When combined with a 2.5” drop spindle, 29” tall tire, and Porterbuilt Tubular Control Arms, the Level 2 Front will set the bottom of the cab approx. 4-6" inches off the ground at ride height.

Ride Height - 4-6"

1963-72 Dropmember Level 2 Front Coilover

The Version 7, Level 2 Front Dropmember system for 1963-72 Chevy Pickups is designed to replace the factory cross-member and steering system. Engineered as a modular bolt-in unit, its advantages include:

  • - 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

When combined with a 2.5” drop spindle, 29” tall tire, and Porterbuilt Tubular Control Arms, the Level 2 Front will set the bottom of the cab approx. 4-6" inches off the ground at ride height.
