Crafted from durable materials, this spring restores the essential tension in the reverse servo circuit, ensuring reliable and consistent reverse engagement. As drag racers and performance builders know, reverse servo functionality plays a key role in line pressure maintenance and gear transition integrity. Over time, weakening of the servo spring can lead to sluggish or unreliable reverse gear response.\u003c\/p\u003e\n\n\u003cp data-start=\"0\" data-end=\"39\"\u003e \u003c\/p\u003e\n\n\u003cp data-start=\"0\" data-end=\"39\"\u003eManufactured in the USA to Coan’s high-performance specifications, the COA‑22043 installs directly into the existing valve body without any case modifications.
