The Bilstein 24-186834 is a rear B6 4600 monotube shock, a gas-pressure design built as a direct-fit replacement for stock-height 2007-2014 GMC Yukon XL 1500 and Chevrolet Suburban 1500 trucks. The manufacturer describes the B6 as a bolt-on upgrade for factory suspension, with a 46mm monotube body and a yellow coated housing, and it tunes valving for each application. Compared with worn stock units, the single-tube, gas-charged layout is meant to resist fade during repeated bumps and sustained driving. Application data for this part number excludes trucks with air leveling or Z55 AutoRide suspension, so confirm coverage with the manufacturer before ordering. Searchers looking for a 2007 Yukon XL rear shock upgrade or a stock-height Suburban 1500 monotube replacement should check the exact option codes on their truck first.
Owners who want firmer, more controlled rear damping without changing ride height can keep their factory springs with this shock, since the manufacturer states it does not add lift. For a buyer comparing it with a cheaper bargain shock, the value lies in the application-specific valving and the manufacturer's emphasis on durability and corrosion resistance. Installation is a bolt-in job at the factory mounting points, and the manufacturer's mounting guidance says the 4600 series requires no modifications. Use a jack or lift, jack stands, a torque wrench set to the vehicle's specification, and avoid impact tools that can damage threads.
No. The manufacturer designs the B6 4600 as a direct-fit upgrade for stock-height trucks, so it is not a lift component.
The manufacturer states that the 4600 series is designed to fit the original shock mounts with no modifications, and it installs in the same manner as a standard replacement shock.
The manufacturer's mounting instructions advise against impact tools because they can damage threads. Tighten all fasteners to the vehicle manufacturer's specified torque.
This is a moderate DIY job. The manufacturer's instructions call for removing the old shock per the vehicle service manual, then installing the new unit at the original location. Removing the inner fender well panels makes access easier, according to the manufacturer. Have a lift or jack stands, a socket set, and a torque wrench on hand. Self-locking fasteners should be replaced rather than reused, per the manufacturer. On similar 4600-series installs discussed on user forums, owners report that the upper nut sits recessed and the shaft must be held with an Allen key so it does not turn while you tighten. Plan to replace seized or corroded hardware before you start.
