No more crooked compressions or slipped jaws. [Dual-Jaw Sets – Even Pressure Distribution]: Two interchangeable jaw lengths apply force symmetrically, preventing spring cocking. Results in smoother operation and reduced risk of damaging retainers or keepers.

Maintains smooth thread operation and jaw alignment through years of daily use. [Critical Usage Note]: Confirm throat clearance and jaw opening exceed your spring dimensions before purchase. Not compatible with deeply recessed valve spring designs. Always wear eye protection – compressed springs store significant energy.
