Review on ACDelco 45H2165 Professional Rear Spring by Bryan Covington

I replaced the rear shocks (which were removed) and replaced them with maximum control shocks (all 4) before I knew that my Tahoe 04 had the ZW7 package hanger.

After reading about the ZW7 suspensions, I found that if I wanted to use non-Nivomat shocks ($400+ shocks; the cheapest I found was $250 new, so was that I'd have to replace the rear springs). it a no). The difference in driving is incredible. Negotiating speed bumps and bumpy roads is now comfortable, and overall the ride is smooth; feels much stronger and more stable. They are ideal for your needs in non-heavy conditions. Those ending in "64” are for heavy-duty applications.
