Recreational Motorsports has developed a low cost clutch spring tester that is a must for the serious tuner or service department. The tester costs a fraction of the price of other high tech brands. Our tester is made from billet aluminum and has a choice of 2 gauges. The 0 to 400lb gauge reads in 5lb increments and the 0 to 600lb gauge reads in 10lb increments. Both have a +/- 2% accuracy and can be used in a vise, press, or everyday drill press.
