Description
Stock shocks limit your Harley's handling potential and comfort, especially if you're regularly riding near maximum load capacity. The Progressive 412 Series delivers a straightforward suspension upgrade with adjustable preload and proven durability—giving you the control to dial in your ride without breaking the bank. Built tough for heavy-duty applications, these shocks handle sustained performance demands that stock units simply can't match.
Key Features & Specifications:
- 5-position preload adjuster
- 13" center-to-center length
- Heavy-duty rated construction
- TüV approved (certified)
- Bolt-on installation
- Harley-specific fitment
- Black finish
- MPN: 412-4020B
Important Installation Notes:
- 1986-2015 XL models may require chain/belt guard modification for clearance
- Length change slightly alters steering geometry—slightly longer quickens steering response, slightly shorter slows it
- Verify wheel travel clearance before installation to prevent swingarm, exhaust, or tire contact
- Recommended for bikes operated at or near manufacturer max load over 50% of riding time
