Carver C7 Spring

Updated replacement spring for your Carver C7. Updated in 2022, this spring now has weight rating reduced from 800 lbs to 550 lbs, so you now get more lower end adjustment for looser carving and easier pumping, while still having plenty of stiffer tension for tighter performance adjustments. The spring is constructed from Rocket Wire, the best aerospace material Carver could find for the longest continuous use possible. They also go to the extra steps of peening the surface, which is a way to polish the surface so there are no minute cracks that can grow over time and contribute to Spring failure, they also lightly oil them to prevent surface rust that also shortens duty cycle. They recommend that you use a liberal amount of Marine Grease during installation (it’s what was used at the factory) or a high quality bicycle bearing grease for quiet and long-lasting action.
