Product Details

The Progressive Suspension 03-1370B are dual rate replacement shock springs designed specifically for Progressive Suspension 412 and 440 series motorcycle shocks. Sold as a pair, these springs offer a progressive 90/130 lb/in spring rate that delivers a compliant ride under light loads while firming up progressively as suspension compression increases — giving you both comfort and control without compromise.

Key Features:

  • Dual progressive spring rate: 90/130 lbs/in (1.61/2.32 kg/mm) for a versatile, responsive ride
  • Compatible with: Progressive Suspension 412 and 440 series shocks
  • Fits: 11" and 11-1/2" shock lengths only
  • Free length: 8.5 inches (216 mm)
  • Spring outer diameter: 1.85 inches (47 mm)
  • Black powdercoat finish for a clean, corrosion-resistant appearance
  • Sold as a pair

Installation Note: A spring removal/installation tool — such as the Progressive Suspension 910-144 spring tool — is required to replace these springs. Professional installation or an advanced level of mechanical skill is recommended.

Quick easy painless

I found it fairly quickly and without much hassle, however i was unsure if it was the part i needed because of lack of details.

Prices were good and the order shipped promptly. The email notice of shipment was a little late. It came after the order had arrived.

Product delivered as expected within 4 days. Lowest price on the web. No complaints.

This was an easy transaction, keep me notified thoughout the entire shipment. Price is what got my attention in the first place. I will be back for future needs.

Nobody else had part in stock. Instant shipping and a good price. Will do business again!
