Why Builders Choose CORE 4X4
Warranty facts, not marketing language.
Their “lifetime” language refers to their service model. Actual parts warranty: 1 year. Ours: lifetime.
Skip a maintenance interval? Their warranty voids. Ours doesn’t.
Clayton warrants their Johnny Joints for 90 days. We cover ours for life.
