Engineered specifically for 2023 Ford F-250 and F-350 4WD diesel trucks, this radius arm kit restores critical suspension geometry and driveline angles when paired with a 4.5‑inch lift system.

Replacing undersized OEM components with precision-matched arms that correct pinion angles, maintain proper differential height, and eliminate binding under maximum suspension compression.

• High-strength billet aluminum fabrication replaces failing factory castings, delivering rigid pivot points that absorb heavy loads without warping or excessive flex.
• Lengths calibrated precisely for the 4.5‑inch lift profile correct CV shaft and transfer case angles to prevent premature driveshaft and U-joint failure.
• Restored factory kinematics preserve steering feedback and ride smoothness, eliminating the vague tracking common with uncorrected lift installations.
• Zero-degree camber and stable caster settings keep footers aligned with stock-offset wheels up to 35 inches wide, reducing accelerated edge wear.
• Complete installation package includes grade‑8 hardware, sealed spherical bearings, and serviceable zerks for straightforward bolt-on assembly without drilling or welding.
• Verified compatibility spans 2017 through 2023 Ford F‑250/F‑350 Super Duty crew and extended cabs with 4WD diesel powertrains, specifically addressing the sagged rear housing typical of high-output engines.
• Every unit receives zinc-chrome corrosion protection and static load validation to guarantee long-term structural integrity under repeated trail compression and heavy-towing cycles.
