The 2135QTL-2 delivers 780 ft-lbs of max reverse torque to get lugs off in a hurry but limits forward torque to 75 ft lbs to avoid stress on the wheel studs and overtightening. It reaches target torque in just 2-3 seconds, is quiet on the job and weighs in at only 4.3 lbs. Driven by a finely tuned impact mechanism and motor that bleeds air instead of delivering a glancing blow, the 2135QTL-2 is 3X more durable than our previous torque limiting impact wrenches. Engineered as the ultimate torque wrench counterpart, the 2135QTL-2 is built for convenience and quality.
