Progressive Suspension 422-4035C 422 Series Shocks

Pair of steel bodied, monotube dampers wrapped with a black powder coated, progressive rate steel coil spring. Dampers feature a nitrogen charge that eliminates cavitation and creates a consistent ride performance with no fading. Fully adjustable Softail shock with adjustable ride height up to 2in. and preloaded. Show chrome quality cover that includes 4 ports for coil spring visibility. Riding 2-up with stuffed saddle bags and enough gear to live out on the road can quickly overwhelm the Softail suspension system. Progressive solves this challenge by adding a higher rate spring to their already fully adjustable shock, providing better load and bottoming control. Combined with variable ride height and tunable spring preload one can easily set up the suspension to fit the bike as well as riding style.
