|490 Sport series shocks
"A true sport performance shock at heart at an unbelievably low cost," Progressive Suspension's new 490 Sport series shocks feature a high-pressure monotube with deflective disc damping technology, hand threaded preload and a rebound adjustment to dial in the ride.
"This technology, coupled with a linear rate spring, allows for consistent feel through the damper stroke and the ability to withstand extreme temperature ranges and heavy loads. An engineered jounce bumper with a built-in metal cup also helps smooth out and control bottoming."
Also seen here, Progressive says it has "gone back to the drawing board and created a state-of- the-art fork cartridge kit designed to outperform everything on the market," and that this fork monotube kit with external preload adjustment means "true high performance front suspension is finally available for H-D 49 mm front ends."
The new asymmetrical design places a preload adjuster over a progressive rate spring in one leg and an aluminum bodied, sealed cartridge damper on the other. "The result is superior damping and ride control combined with tuneable preload and a new benchmark for high performance suspension on the 49 mm Dyna and Sportster platforms."
