The Bilstein 5100 Series 33-238319 is a rear shock absorber built as a 46mm monotube for the 2014 Chevrolet Silverado 1500 and GMC Sierra 1500 pickups. It replaces the factory rear damper with a single-tube design from the 5100 line. Buyers searching for a 2014 Silverado 1500 rear monotube shock, a Sierra 1500 rear performance shock, or a Bilstein 5100 rear shock 33-238319 will find the part number and vehicle match below.
The monotube layout is the main reason to choose this unit over a stock or budget twin-tube replacement. Enthusiasts generally favor monotube construction because the damping piston runs in one pressurized tube, which supports steadier damping when a truck is driven hard on rough pavement, gravel, or trails. For owners who tow, haul, or run larger tires, a rear shock with a more controlled damping response can make the truck feel more planted over repeated bumps. A cheaper unit may cost less at the counter, but it gives up the build quality and specification focus that this line is known for.
Fitment should be checked against the truck before ordering. Confirm the 2014 model year, rear position, and whether the truck is 4WD or 2WD, since the listing is intended for those pickups. If the rear of the truck has been lifted, lift tolerance details vary across sources, so confirm the supported lift range with the manufacturer before buying. Replacing the rear shocks in pairs keeps both sides matched for consistent ride height and damping.
