These high-quality, high-performance replacement progressive rate fork springs by Californian specialist Progressive Suspension have the advantage of a rising rate resistance to compression - the benefit is the spring can be soft enough at the start of the travel to offer a "plush" ride, yet firm enough at the end of the cycle to soak up the big bumps.
Spring rates have been chosen to reduce front end dive during braking, yet still provide excellent ride comfort; available for '16-'17 FXDLS models.
Also seen here, this monotube cartridge fork kit has an asymmetrical design, placing a preload adjuster over a progressive rate spring in one leg and an aluminum-bodied, sealed cartridge damper on the other.
This set-up is said to provide superior damping and ride control combined with tunable preload and to be "a new benchmark for high-performance suspension, improving resistance to front brake dive, front end stability, cornering and bottoming control; adjustable to standard length or to lower the front end up to 1"."
This is a complete fork internal replacement kit - no modifications to the forks are required, meaning the install is fully reversible. Available for FXDS.
