Replacement Spring, Helux Pin Box, 1,500 lb./in.

If it’s time to swap out the coil spring on your Helux™ pin box, this is the replacement you’ll want. It’s made specifically for the Helux coil-spring system to help bring back that smooth, steady ride you’re used to. The spring is tested to SAE J2638 safety standards and holds up well in tough conditions — 250 hours of salt-spray testing proves it can handle the road and the weather. A durable powder coat finish helps protect against rust and corrosion, so you’re set for the long haul. B sure to check your service manual before ordering to confirm you’ve got the right part.
