We love to hear back from customers on how their lift kits are holding up and what they are putting them through. Jake Prchal send in photos of his 2012 Ford F350 Super Duty running the Zone 6” radius arm lift kit on 37s. Jake had this to say about the kit: Love the Zone 6 inch radius arm system for ease of installment and top notch durability!Ā The lift is great and works well in mud too! šŸ™‚ Thanks, JakeĀ Ā from Minnesota
