CP3945 is a "heavy Duty" version of CP3985 air jacks. It has a compression spring rather than the conventional tension return spring making the air jack faster and more efficient in operation. The new range incorporates a larger ram section thus improving strength, however this has a trade off against weight as the new variants are 30-40 grams heavier than CP3985 types.
