Ridgid 31730 Coil Flat Spring Assembly for 4A502 Wrench 36 in

Spring Assembly for 36 in Wrench

The Ridgid 31730 coil and flat spring assembly is a genuine replacement part built for the 4A502 wrench with a 36 in overall length. It restores the internal return mechanism so the tool cycles correctly during pipe and bolt work. Mechanics and maintenance crews who service this specific wrench model use it to return the tool to full function.

Consistent Return Force Under Repeat Use

The spring assembly is engineered to deliver repeatable tension across extended tightening and loosening sequences. It resists fatigue that would cause the wrench to stick or return slowly during long service intervals. The component maintains its calibrated pressure so the ratchet action stays predictable job after job.

Verify Model Numbers Before Ordering

Confirm the wrench carries the 4A502 designation and matches the compatible model numbers 31035, 31085, 31110 or 31380. The part is not interchangeable with other Ridgid wrench lengths or series. Buyers who need springs for different wrench sizes or other tool brands will need a separate component.
