Progressive Suspension Shock 490 13 Sportster

True sport performance shocks

Feature a high-pressure monotube with deflective disc-damping technology, hand threaded pre-load and rebound adjustment

Linear rate spring allows riders to fine tune the damping and consistently withstand extreme temperature ranges and heavy loads

Engineered jounce bumper and cup also help smooth out and control bottoming

Made in the U.S.A

All shocks are measured center-of-eyelet to center-of-eyelet

A shock which is slightly longer than stock may alter the head angle slightly and provide somewhat quicker steering

A shock which is slightly shorter than stock may alter the head angle slightly and provide somewhat slower steering

For OEM shock lengths, see Quick Reference Guide in the back of the catalog

Heavy Duty Applications are recommended for bikes that are operated at or near the manufacturer's maximum load rating over 50% of the time

Before purchasing or attempting to install shocks that are different than the OEM length, confirm that your wheel travel can be altered without causing clearance issues, such as swingarm/axle to exhaust contact as well as chain/belt guard or tire contract
