Hairpins Rated by John on August 04, 2022
Summary: These look good and I wanted the longer hairpins for the front of my Bantam. The threaded ends were packed with something to protect the threads, but they all had grit mixed in so clean thoroughly before installing rod ends. One end of one of the hairpins had sightless damaged threads. Had to buy a tap but an easy fix.
Yes, I recommend this product.
