Progressive Suspension 412 Series Shocks — 279.4 mm extended length, Chrome

The 412 Series Shocks are designed specifically for Harley models, offering a simple, durable upgrade that improves suspension performance.

Key features:

• Five-position cam-style spring preload adjuster lets you easily dial in your ride.
• Multiple style options including high-shine covers or darker finishes and alternate spring/end-cap treatments.
• Measured center-to-center for consistent fitment; some applications may require minor modification or spacing of the chain/belt guard for proper clearance.
• Heavy-duty options recommended for frequent operation near maximum load ratings.
• Some listings are approved for road use; refer to the most recent certificate for current listings.

Before purchasing or installing shocks that differ from OEM length, confirm wheel travel and clearances to avoid swingarm/axle to exhaust contact or chain/belt guard or tire interference. A slightly longer shock can quicken steering; a slightly shorter shock can slow it. Made in the USA.
