Bumper Set, 27" Torpedo

27" Torpedo Bumper Set – Pair of Return Springs for Sectional Garage Doors

This 27" Torpedo Bumper Set is designed to address one of the most common issues with jackshaft-operated or back-traveling sectional overhead garage doors: cable slack. When a sectional door opens and reaches the back of the track, it can cause tension loss in the lift cables. These heavy-duty return springs help maintain proper cable tension and return the door to a resting position gently and safely.

Built for durability and consistent performance, these bumpers offer a 15-inch travel range and approximate spring compression of 10 lbs/inch—ensuring reliable support without harsh impact. The set includes two springs with pre-installed 12-gauge brackets for easy mounting with 3/8" bolts.
