Frequently Asked Questions

Will these fit my 2004-2013 Sportster?

Yes, these fit 2004-2013 Sportsters. If you choose the 14 in tall shocks, you may need to relocate the rear master cylinder to clear the longer shock body.

What's the difference between the 12.5 in and 14 in lengths?

12.5 in is stock ride height; 14 in gives the taller curb-hopper or club-style look with extended rear suspension geometry.

Can I adjust these shocks after installation?

Yes — the shocks feature full adjustability. Preload, compression, and rebound can all be tuned via external adjusters without disassembly.

Do these fit FXR models?

Yes — these shocks fit 1982-1994 FXR models with compatible frame mounting points.

What's the advantage of Speed Adaptive Valving?

SAV automatically adjusts damping based on suspension velocity, providing consistent performance across different riding speeds and road conditions without constant manual adjustment.
