Specs At A Glance

Good To Know

Q: Will this change the unloaded ride? A: Helper systems engage mainly under load, so empty-truck ride typically stays close to stock. Q: Does it require drilling? A: Most kits of this type bolt to existing points, though you should confirm hardware and procedure for your truck before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
