  The
440 I.A.S. is Progressive’s top-of-the-line shock. |
 ooking
for a set of high-performance shock absorbers to really soak up the bumps,
dips and bangs of hard road riding, shocks available for OE replacement
on all the popular twin-shock cruiser bikes and even in shorter lengths
for a slammed-down custom stance? Take a look at the Progressive Suspension
440 Series I.A.S. Shocks, offered in brilliant chrome or a tough black
powder coat finish. Set them up with the 440 I.A.S. Series and you’ll
have some happy and extremely comfortable cruiser-bike customers.The 440 Series I.A.S. shocks work as well as they do thanks to Inertia Active System technology (I.A.S.). It’s a revolutionary breakthrough in shock-absorber technology, originally developed and patented for automotive use by Edelbrock. I.A.S. is featured in all Edelbrock performance- and off-road shocks. Progressive Suspension licensed this technology and further refined it for motorcycle use. The 440 Series I.A.S. Shocks are the only motorcycle shocks to offer this level of performance. I.A.S. technology utilizes two completely separate rebound-damping circuits to independently control chassis and wheel movement. There’s both inertia-sensitive and velocity-sensitive damping in the same shock body. The result is great stability, handling and comfort. Add to this Progressive Rate Springs that are pre-load adjustable with no tools required and the combination is a cruiser shock clearly at the top of the field. There are polished and anodized billet aluminum end covers, too, and all this comes with a limited lifetime warranty, something brand-new from Progressive Suspension. Retail pricing is just over $500. The 440 Series I.A.S. Cruiser Shocks are available now. Parts Unlimited has them in stock, in all the sizes, applications and finishes.  |
