Product description

Safety is paramount in any automotive shop, and the BH-9633 Oil Valve Return Spring (also known as the "Dead Man Spring") is a critical safety component for Weaver and Rotary lifts. This spring ensures that when the operator releases the control handle, the hydraulic valve automatically returns to the "neutral" or "hold" position, preventing the lift from continuing to move. Over years of use, springs can lose their tension or break due to fatigue, creating a serious safety hazard. SVI International's replacement spring is manufactured from high-grade spring steel, designed to maintain its corrective force through thousands of cycles. Replacing a weak spring is a simple but vital maintenance task that protects both the technician and the vehicle being serviced.
