Product Description
The Astro Pneumatic 78810 is a professional 10‑piece torque‑limiting extension set designed for fast, accurate, and repeatable wheel‑service torque control. Built from lightweight aluminum for easy handling, each 8‑inch extension is engineered to flex at a specific torque value, preventing over‑tightening when using an impact wrench. This protects wheel studs, brake rotors, and alloy wheels while ensuring consistent torque application across cars, SUVs, and light trucks.
Ideal for tire shops, automotive technicians, and mobile mechanics, the 78810 set covers the most common torque ranges used in modern passenger vehicles. Each extension is color‑coded for quick identification, and the 1/2" drive design works with all standard impact tools. Whether you're rotating tires, installing wheels, or performing brake service, this set delivers reliable torque control and professional results.
