Frequently Asked Questions
What is RAP and how does it work?
RAP (Remote Adjustable Preload) is a dial adjuster mounted behind the left passenger peg that lets you tune shock preload without removing the shocks — perfect for passenger weight or cargo changes.
Can I lower my Softail with these shocks?
Yes — these shocks are adjustable from stock height down to 2 inches lower, giving you ride-height customization.
Do these fit 2000 and newer Softail models?
No — this part number is for 1988-1999 Softail chassis. 2000-up models require different shocks.
What's the difference between Standard and Heavy Duty versions?
Heavy Duty valving is tuned for heavier loads and aggressive riding, while Standard is for typical street use. Both have the RAP system.
Will I need to adjust preload often?
Most riders adjust preload when adding a passenger, carrying luggage, or when ride feel changes. The RAP system makes these tweaks quick and tool-free.
