set of Progressive Suspension's 440 Series shocks will transform a metric cruiser. No exaggeration there. The PS 440s with their unique Inertia Active System (IAS) will keep the rubber planted and the rider smiling. IAS technology, developed by Edelbrock and refined by Progressive Suspension for motorcycle applications, uses two completely separate rebound/damping circuits in the same shock body. One circuit is inertia-sensitive, the other velocity-sensitive. The result is enhanced stability, greatly improved handling - especially when compared to an OE shock - real chassis and wheel control and seat of the pants comfort. The 440s also use Progressive Rate Springs, pre-load adjustable with no tools required. The PS 440s are available in a number of different lengths so you can fine-tune the ride height to the application and the shocks are even available in Standard or Heavy Duty ratings; Progressive Suspension custom calibrates the springing and damping for either solo riding or two-up touring.
     And now, with applications for all the Honda, Kawasaki, Yamaha and Suzuki cruisers that can use them, the Progressive Suspension 440 Series shocks are available in a choice of finishes. There's the original Polished Aluminum look with chrome springs, thereÕs Bright Chrome, Black Chrome and a tough Black Powder Coat. No matter what color the motorcycle might be, or what style it's been modified to, there's a 440 Series shock thatÕll add a custom appearance to go with the custom performance.
     When's the right time to make that switch to Progressive Suspension? Anytime, really, even on a brand-new bike, but the rule of thumb has it that when you're replacing the tires for the second time it's time to replace the shocks. You won't go wrong replacing those OE shocks with a set of PS 440s, especially with all those custom finishes available.
Retailing at a little over $500 for the set the Progressive Suspension 440 Series shocks are price competitive, and Parts Unlimited has them in stock in all the lengths, ratings and finishes. Call your rep today.
