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.

Precision Alignment and Drivability Enhancement

These adjustable upper control arms allow precise pinion angle correction, ensuring smooth power delivery and reduced drivetrain stress. By pairing them with our Rear Lower Control Arms, you get full axle recentering and alignment correction, preventing excessive tire wear and instability.
Two-Stage Powder Coating for Maximum Durability
All control arms go through a two-stage powder coating process to ensure corrosion resistance and long-lasting durability: Zinc primer base coat – Provides enhanced rust protection. Durable top coat – Available in 10 color options, allowing you to customize your suspension’s look.
