Billet Aluminum Electronic Coil Spring Tester

  • 0 - 3000 lbs. by 1 lb.
  • Travel to .001"
  • 6" to 20" tall springs
  • Coil and coil-over springs, 5" or 5-1/2" OD, flat or 'pigtail' ends (one end must be flat)
  • Includes easy-to-use digital indicator to measure spring travel and a digital load readout

IMPORTANT NOTE:  You MUST preload the spring to a minimum of 1/2". Manufacturers rate springs with a higher preload. The higher the preload, the higher the spring rate because the end coils start to touch, effectively shortening the spring. Without adequate preload, readings may be inconsistant. Coil springs - even the best quality - can vary as much as 5% from the stated rate. This is normal manufacturing tolerance.

The distance between the insides of the posts is about 8.5”.  The coil spring retainers/”buckets” are setup for a max pigtail diameter of 6” (they measure about 6.13” ID).

Metric option: Choose the metric with 220V charger option above and we'll configure it to display in kilos and substitute the appropriate charger.

Note: Batteries not included. Please purchase (2) CR2032 batteries for use.
