I installed 2.5" coil lifts in the rear of my 2013 Avalanche. I ordered a set of ReadyLift 67-3809 Rear Shock Extension Bracket and wonder if anyone has installed these shocks extensions and where on the shocks... top or bottom of shocks.
From the ReadyLift 67-3809 product page on PerformanceTruckProducts.com:
"ReadyLift now offers specially designed Rear Shock Extensions for 1999-2010 Chevy Silverado and GMC Sierra 1500 2WD and 4WD trucks. These tough powdercoated steel shock extensions install in the factory upper rear shock mount to greatly decrease the chance of over-extending the factory shocks."
