Designed for 2–4-inch lifts — These upper control arms are engineered for 2004–2025 Titan and 2005–2019 Armada models, compatible with 2–4-inch front lift kits. They maintain proper ball joint angles and suspension geometry while preserving wheel arch and tire clearance. Premium PU Bushings: Featuring high-performance polyurethane (PU) bushings, these control arms offer superior resistance to wear and tear compared to traditional rubber bushings. PU bushings provide better handling and a more responsive driving experience, ensuring that your vehicle's suspension remains tight and controlled. The Grease Ball Joints: Each control arm comes pre-installed with grease-injectable ball joints, plus an additional pair of replacement ball joints is included. The ball joints support grease maintenance for easy upkeep and long-lasting performance. Their dust- and dirt-resistant construction effectively extends service life. Wrinkle-Red Finish — Tubular arms feature a red/wrinkle-red surface treatment that not only delivers a striking visual appearance but also enhances wear resistance — ideal for frequent water crossings, dusty conditions, or variable climates. Restores suspension geometry and improves handling stability — After suspension lift or tire size increase, OEM arms may cause improper ball joint angles, suspension sag, or steering drift. This replacement arm restores correct geometry, reduces suspension offset, enhances driving stability, and extends tire life. 2-4" Lift Front Upper Control Arms for 2004-2025 Nissan Titan, 2005-2019 Nissan Armada, Tubular Arms OEM Factory Replacement Part, PU Bushing, 2 Replacement Ball Joints, Wrinkle Red
