Spring design
Rate type: Constant / linear.
Except where a specific lift or stock-height application is noted above, the spring range is designed around loaded stock height plus approximately 1 inch. Empty ride height varies with engine, trim, equipment and vehicle load. HD/XHD percentages are load-at-height comparisons, not guaranteed lift amounts.
Features
- Designed for improved handling, loaded ride quality and cornering stability.
- Suitable applications include work vehicles, fleets and continuous hauling; diesel or snowplow suitability only where specified above.
- No periodic spring maintenance required.
- Designed to help reduce driver fatigue under loaded conditions.
- Manufactured in North America.
Confirm chassis, engine, drivetrain, axle, original spring and any conversion equipment before ordering. Never exceed the vehicle manufacturer’s GVWR or axle ratings. Springs do not increase those ratings.
