Progressive Suspension 412-4058C 412 Series 14.25" Chrome Rear Shock Absorbers

The Progressive Suspension 412 Series rear shocks deliver a proven, cost-effective upgrade over factory suspension. Built with a double-wall steel body and nitrogen-charged, multi-stage velocity-sensitive valving, these shocks provide smooth, consistent damping mile after mile. The simple, durable design ensures long-lasting performance improvement over stock OEM units.

Key Features:

• Double-wall steel body construction with high-pressure nitrogen charge for consistent damping performance
• Multi-stage velocity-sensitive valving delivers smooth, controlled ride quality in all conditions
• 5-position cam-style spring preload adjuster lets you easily dial in ride firmness to match rider weight and load
• Progressive rate spring in chrome finish — available in Standard or Heavy-Duty rates for select applications
• Sold in pairs — includes all mounting and adjusting hardware
• Made in the USA with a one-year warranty

Standard vs. Heavy-Duty: Heavy-Duty spring rate applications are recommended for riders 250 lbs or more, or those who ride two-up more than 50% of the time, or operate the motorcycle at or near the manufacturer's maximum load rating on a regular basis.

Important Installation Note: If installing shocks that differ in length from your OEM units, verify that the altered wheel travel does not cause clearance issues, including swingarm/axle-to-exhaust contact or chain, belt guard, or tire contact.
