Why Spring Thickness Matters

Rear springs play a major role in how a coil machine cycles, recovers, and hits. A .018" rear spring offers a responsive feel with enough strength to maintain consistency without becoming overly rigid. It's a popular choice for artists who want a machine that feels controlled while still staying lively and responsive.

Whether you're replacing worn springs or fine-tuning a custom setup, the right rear spring can completely change the way your machine performs.
