Our suspension system for the venerable Softail style chassis is exclusively available as an adjustable ride height version. Progressive Suspension was the first to introduce aftermarket shocks for the most popular frame design ever produced and we continue to refine our work. Two inches of ride height adjustment as well as adjustable for spring preload to accommodate varying loads and rider weights, all wrapped in a chrome shroud and now available in a HEAVY DUTY version for two-up or heavily loaded bikes!
