The Bilstein B6 4600 rear shock (part 24-185967) is a 46mm monotube gas shock made as a direct-fit replacement for the stock rear shocks on 2WD Nissan Titans. The manufacturer's fitment table lists 2004 through 2015 Titan 2WD rear applications, and the company builds the B6 4600 line as an upgrade for stock-height light trucks and SUVs, so it installs without adding lift. The monotube body is meant to resist fade on rough or repeated-bump driving, which is the main reason to choose it over a worn factory twin-tube rear. Owners on user forums who replaced tired original rears describe a clear improvement in control, though some report the change is subtle on a 2WD truck at stock height, so set your expectations accordingly.
Search terms this part answers include Bilstein B6 4600 24-185967, 2004-2015 Nissan Titan 2WD rear shock, 46mm monotube gas shock Titan, and stock height rear shock replacement. At roughly six pounds per unit, the shock is a straightforward, bolt-in upgrade for a daily-driven or light-hauling truck that needs better damping without the cost of a lift-specific system. Because the manufacturer's series listings call for two shocks per vehicle, buy them as a pair so both rear corners match.
The manufacturer lists this rear part for 2WD (RWD) trucks only. 4WD Titans use separate Bilstein part numbers, so confirm the drive type of your truck before ordering.
No. The manufacturer designs the B6 4600 for stock-height trucks and does not position it as a lift product. Owners on user forums note that shocks do not add height; springs, blocks, or shackles are what change ride height.
The manufacturer's fitment table covers 2004 through 2015 Nissan Titan 2WD models, not only the 2004 LE. Check your model year and drive type against the manufacturer's application list.
Owners on user forums generally rate the rear swap as one of the easier suspension jobs on these trucks. One owner reported replacing the rear shocks without removing the wheels or jacking the truck off the ground. The most common problem is a seized lower mount: owners recommend soaking the lower eyelet with penetrating oil, using a puller if needed, and applying anti-seize to the post before the new shock goes on. To keep the upper shaft from turning while you loosen its nut, owners hold it with an adjustable wrench or an oil filter wrench. A commonly suggested method is to start the upper mount by hand, then use a floor jack to raise or lower the axle until the lower eyelet lines up. Torque the hardware to the factory service manual specification; one owner cited 155 ft-lb for grade 8 hardware, so verify that figure before tightening. Do not drive with a shock disconnected, as owners warn the axle will bounce badly.
