Chevy GMC Silverado Sierra 1500 Pickup Rear Clip Leaf (#2 / Middle Leaf) Attention: If your clip leaf (the middle leaf) is broken, your entire spring may not need to be replaced. This is VERY common with the trucks using 3 leaf springs. Many GMC/Chevy trucks with low to medium miles on them tend to break their clip leaves off. Many times when the clip leaf breaks, it will slide out of place and slip under the bottom leaf causing many people to mistake it for the bottom leaf being broken.
