Frequently Asked Questions

Do I need to adjust these cartridges after installation?

No — they ship pre-tuned and ready to ride. Preload, compression, and rebound are adjustable if you want to dial in the setup further.

Will these fit my 2006-2017 Dyna?

Yes — these cartridges are designed for 2006-2017 Dyna models. You will need 2" longer fork tubes to accommodate the +2" cartridge length.

What do I need to install these besides the cartridges?

You will need new fork tubes that are 2" longer than stock. The cartridges themselves bolt into the new tubes.

Can I adjust preload, compression, and rebound?

Yes — all three are adjustable with 24-click ranges on compression and rebound, plus 15mm of preload travel on each side.

What makes these different from cartridges for other Harley models?

These are tuned specifically for Dyna geometry and weight. Bagger versions use similar tech but lack external adjusters due to installation constraints.
