Frequently Asked Questions
Do these mount using factory attachment points or do I need to drill?
These mount at existing rocker panel points — no drilling required. You'll need basic hand tools and fasteners rated for your vehicle's rocker attachment standard.
Does the powder coat finish need any prep before install?
The finish is ready to install as-is. If you're concerned about contact points, wipe mounting surfaces clean and consider applying a thin coat of touch-up paint where brackets meet the rocker panel.
Are mounting bolts and brackets included?
The bars ship bare — verify your truck's factory rocker fastener size before ordering hardware. Most extended cabs use M10 or M12 bolts; refer to your service manual for exact specs.
