For maximum durability and corrosion resistance, all control arms undergo a two-stage powder coating process: Zinc primer base coat – Provides rust protection. Durable top coat – Available in 10 customizable colors for a long-lasting, stylish finish.
Made in the USA
Proudly manufactured in Orem, UT, our Cruise Series components support American craftsmanship and are built to the highest performance and durability standards.
Optional Hardware Upgrade
Installation is straightforward using factory hardware, but for those dealing with rusted or seized bolts, we offer optional Grade 8 hardware kits, available separately for a seamless installation process.
