PROGRESSIVE SUSPENSION 490 Series Shock - Black - Heavy-Duty - 12.00" 490-1006

The Progressive 490 Series Heavy-Duty Shock delivers the damping control and bottoming resistance you need to maintain consistent performance under sustained heavy loads and extreme temperature swings. With hand-adjustable rebound and pre-load, you'll dial in the exact compliance your riding demands—not what the factory guessed.

Important Installation Note: Before purchasing, confirm your bike's wheel travel can accommodate the 12.00" length without causing clearance conflicts—check swingarm/axle-to-exhaust distance, chain/belt guards, and tire contact points. If your shocks differ significantly from OEM length, professional inspection is recommended.
