The ATC TT4500 Leaf Spring Pin Socket Master Set is a professional, heavy-duty service kit engineered for safe and efficient removal and installation of leaf spring pins on major North American truck platforms, including Volvo Trucks, Mack Trucks, Paccar, and Navistar International. Designed for suspension service professionals, this master set provides the correct socket profiles and sizes required to engage spring pins securely without rounding or damaging hardware.
Leaf spring pins are often seized due to corrosion, road debris, and high clamping loads. Improvised tools can slip, deform the pin, or damage surrounding suspension components—leading to added labor time and safety risks. The TT4500 set delivers precise engagement, high torque capability, and controlled removal, helping technicians complete suspension repairs faster and with confidence.
Built for daily shop use, the ATC TT4500 is ideal for fleet maintenance operations, heavy-duty truck repair shops, alignment and suspension specialists, and dealership service bays working across mixed truck brands.
