I have a new strut shock absorber, part# 39105 for a GMC Sierra / Chevrolet Silverado 1500. (This is the shock absorber, so you have to move over the spring from your existing strut). Fits 2007, 2008, 2009, 2010, 2011, 2012, and 2013 model years. I bought a pair but I only needed to replace one. $75.
