King Pin Kit
Mack

This King Pin Kit is a complete front-axle pivot upgrade designed to restore steering geometry and reduce tire wear on heavy-duty applications. The kit typically includes the king pin, bushings, seals, retainers, and related hardware to renew the pivot point where the wheel assembly articulates. Replacing worn king pins eliminates excessive steering play, improves stability during high-speed maneuvers, and enhances load distribution across the front axle. Proper installation ensures proper camber and caster alignment, which contributes to predictable handling and safer braking performance. The kit is selected to match specific axle models and weight ratings, so accuracy matters for optimal results. Once installed, expect smoother steering, improved tire life, and reduced energy loss due to misalignment. Regular inspection after installation helps confirm ongoing performance.
