Is your big GM SUV riding rough or sagging in the back? This is a complete pair (left and right) of rear shock absorbers designed for vehicles equipped with the fancy Magnetic Ride Control system. They fit a ton of trucks from 2007 to 2014: Cadillac Escalade, Chevrolet Avalanche, Suburban, Tahoe, GMC Yukon, and Yukon XL (all the 1500 models). These are NOT just regular shocks – they're the complete strut assembly with the MagneRide tech built-in, so your ride control system keeps working properly. They promise 100% accuracy of fit, are adjustable, and should be a direct swap for your worn-out ones. The part numbers they replace are a long list including 23487280, 19302786, and many more (see the description). They come as a set of two, brand new, with a LIFETIME manufacturer warranty – which is amazing for car parts. The shock type is hydraulic fluid in a single pipe system. If your dashboard is lit up with suspension warnings or the ride is just gone, this pair could be the fix.
