**** Please note that this spring may not work as a direct replacement for many automatic knives on the market today, especially on those where stack clearance is an issue. Designed with custom knives in mind, modification of the coil cavity depth may be necessary for the MEGA Torque Coil spring to fit correctly in an existing knife. Please measure your coil clearance depth before ordering. ****
Note: Please measure your spring size in inches before ordering. A rule of thumb is to measure the center of the pivot to the spring tip hole in the blade and double it for the correct coil diameter, in inches.
