Progressive Suspension Heavy Duty 422 Series Shocks with RAP

• Steel-bodied, monotube dampers, wrapped with a black powder-coated, progressive-rate steel coil spring

• The dampers feature a nitrogen charge that eliminates cavitation and creates a consistent ride performance with no fading

• The 422 series is a fully adjustable Softail shock, with adjustable ride height and spring pre-load

• The shocks are impressive with a show chrome quality cover that includes 4 ports for coil spring visibility

• RAP (or Remote Adjustable Preload) and it combines their high performance shocks with a remote preload adjuster

• Conveniently located behind the left passenger peg, their RAP system allows for easy turning of the shocks to account for changing loads or the addition of a passenger
