The Bilstein B6 4600 Series front shock (part 24-186230) is a monotube, gas-pressure replacement for the front of the 2007–2021 Toyota Tundra. The manufacturer describes it as a direct-fit upgrade to OE shocks on stock-height light trucks, so it mounts to the factory points without modification. Bilstein says the B6 offers a significant improvement in ride quality, handling, and comfort over the factory unit, and its monotube design is built for consistent, fade-free damping. For a truck that tows, hauls, or runs rough back roads, that stability is the real reason to pay more than for a budget shock, and the limited lifetime warranty backs the purchase.

This is a stock-height part. The manufacturer does not position it for lifted trucks, so buyers running a lift or a leveling kit should look at height-adjustable Bilstein options instead. Installation is not a casual driveway job. The manufacturer states that its shocks require special tools and expert knowledge and should be fitted by a qualified suspension specialist on a chassis hoist. If you do it yourself, the mounting instructions call for a spring compressor when transferring the OE coil spring to the new shock, and removing the inner fender wells makes access easier. Afterward, caster and camber must be checked, and the brake compensator, ABS, and headlight aim should be verified. The manufacturer also says that when replacing other brands, shocks should be installed as a set.
The manufacturer designed the B6 4600 as a direct-fit upgrade for stock-height light trucks and SUVs, so it is not intended for lifted applications.

The manufacturer states that installation requires special tools and expertise and recommends a qualified suspension specialist.
Plan for a difficult job that needs a chassis hoist, a spring compressor if you reuse the OE coil spring, and a wheel alignment afterward. Per the manufacturer's mounting instructions, remove the old shock following the vehicle service manual, slide the new dust boot onto the new shock, and seat the OE spring and mounts in the sequence the instructions show. Plan to replace both fronts together, since the manufacturer recommends installing shocks as a set. Verify caster and camber, reset the brake compensator and ABS if required, and check headlight aim before driving.
