Frequently Asked Questions
What lengths are available?
Progressive offers the 465 in four sizes: 12.2 in, 12.6 in, 13.1 in, and 13.5 in to adjust ride height in 0.8–1 in increments.
Can I adjust the rebound damping?
Yes — the 5-position rebound adjuster lets you tune the shock to your riding style and load conditions.
Is the 16mm chrome shaft durable?
Yes. The hard chrome shaft rides on custom Viton seals for low friction and a leak-free lifespan.
Do I need to choose Standard or Heavy-Duty spring rate?
Choose based on your typical load and riding preference. Progressive offers both rates with the same 2:1 motion ratio geometry.
Will these shocks fit my Softail if it's not an M8 model?
No — these are engineered specifically for M8 Softail models. Older Softail generations require different shock part numbers.
