John Evans’ Sons manufactures custom Torsion Leaf and Torsion bar Springs.
These are used to counter-balance heavy armored hatch covers on military equipment, including:
- Bradley Fighting Vehicle
- M1A1 Abrams tank
- Various other armored vehicles.
These springs, generally stacked together in packs of 8–12 pieces, develop large amounts of torque in a very short deflection. We work with a variety of spare parts contractors including that of OEM and Defense.
