Zone Offroad ZONC74F 1.75" Front / 1" Rear Suspension Lift Kit with Adventure Series UCAs

The Zone Offroad ZONC74F is a suspension lift kit engineered specifically for AT4 and Trail Boss trim trucks. The front lift is achieved through a 3-piece strut spacer system — a top mount spacer combined with two preload spacers — which raises ride height without over-extending the suspension during droop travel. The rear uses a block kit. Critically, this kit includes high-strength Adventure Series upper control arms (UCAs), which deliver more suspension travel, improved strength, and corrected geometry compared to kits that retain the factory UCAs. The result is a setup that maintains stock-like ride quality and handling while creating clearance for 33–34" tires. Also included are hardware packs, steering stop extensions, and Factory Protection Plus coverage.

This kit fits select 2019–2025 Chevrolet and GMC 1500 models. Note: This kit will NOT fit AT4X or ZR2 models equipped with Multimatic shocks. Stock wheels and tires will require a 1/4" wheel spacer to clear the upper control arm. Control arms typically add 1–2 degrees caster above stock alignment specifications — a professional alignment is recommended after installation. For replacement ball joints, use service kit ZONF8202; the ball joint is directional and must be installed with the dot facing the correct direction to avoid damage.
