How to select the correct spring (Please Read in Product Description and see detail step1-4 in picture) Step 1 is to measure the wire diameter. To do this you will need to measure 10 coils then compare that measurement to the chart below to see the wire size,double check by measuring 20 coils and compare to the 10 coil measurement (Please see detail in picture No.3) Step 2 is to determine the spring inside diameter, if the spring is broken you can simply use a ruler to measure the inside of the broken end, if the spring is still in one piece you can measure the outside and deduct the wire size X 2. (Please see detail in picture No.4) Step 3 is to measure the length of the spring, Measure the spring only, not including the winding and stationary cone. (Please see detail in picture No.4) Step 4 is only important if ordering a single spring, determine the wind direction of the spring, ( right hand wind ( RW) or left hand wind (LW). Below is an example of the different spring winds. (Please see detail in picture No.4) Left wind torsion springs have the wire ending on the left when viewed from the end of the spring.
