Weihrauch HW 35 Main Spring 9004

The Weihrauch HW 35 Main Spring 9004 is a precision replacement spring designed to restore the original performance of your Weihrauch HW 35 air rifle. As the driving force behind the spring-piston mechanism, it stores the energy required to propel the piston, delivering smooth cocking, reliable power, and consistent shot-to-shot performance.

Over time, the spring can lose tension through regular use, resulting in reduced power, lower velocity, and inconsistent firing characteristics. Replacing a worn spring restores the rifle's efficiency and helps maintain the smooth operation the HW 35 is known for. For the best results, it is recommended to inspect or replace the piston seal and breech seal at the same time.

Manufactured to precise specifications, the 9004 spring provides an accurate fit, excellent fatigue resistance, and long service life. It is the ideal replacement for maintenance, repairs, or a complete overhaul of your Weihrauch HW 35.
