Product Details

The Progressive Suspension 03-1370C are dual rate replacement springs designed specifically for Progressive Suspension 412 and 440 series shocks. Featuring a 90/130 dual spring rate, these springs deliver a compliant initial ride that progressively firms up under heavier loads or aggressive cornering, giving riders a balanced combination of comfort and control.

Key Features:

  • Dual rate spring design: 90/130 lb/in rating for progressive, load-sensitive performance
  • Compatible with: Progressive Suspension 412 and 440 series shock absorbers
  • Fitment: Fits 11" and 11-1/2" shocks only
  • Chrome finish for a clean, classic appearance
  • Spring replacement tool required — compatible with Progressive Suspension tool 910-144

These springs are an ideal upgrade or replacement for riders looking to fine-tune the suspension performance of their 412 or 440 series shocks. Note that a spring removal tool (such as Progressive Suspension part 910-144) is required for installation.
