If you want to level the front of a Tacoma, 4Runner, Tundra, Sequoia or Lexus GX with Bilstein, you will end up choosing between two parts: the B8 5100 (Ride Height Adjustable) and the B8 6112 coilover kit. Both bolt into the factory front mounts and both let you set the front ride height with snap-ring grooves on the shock body. The difference is what comes in the box and how big the shock is.
The short answer
- 5100 (Ride Height Adjustable): a 46mm Bilstein shock with an adjustable spring seat that reuses your factory front coil spring. Bilstein pitches it as a practical alternative to coil spring spacers for mid-size and half-ton trucks and SUVs.
- 6112: a front coilover kit with a larger 60mm shock, Bilstein's own springs and billet spring seats. Bilstein says it is for leveling, more ground clearance and larger tires on late-model trucks and SUVs with a front coilover.
Choose the 5100 if you want to level on the stock spring. Choose the 6112 if you want the bigger shock and new springs in one kit, or plan to add weight up front.
Side by side, from Bilstein's specifications

|---|---|---|
| Position | Front, sold as single shocks | Front, sold as a kit |
| In the box | One shock with adjustable spring seat | 2 x 60mm shocks, 2 x billet hard-anodized spring seats, 2 x springs |
| Piston | 46mm | 60mm digressive |
| Body diameter (examples) | 2.0 in (24-232173, 24-333207) | 2.65 in (47-329232, 47-333246) |

The headline lift numbers are Bilstein's general figures. Each part's own application list is more exact, and it often varies by trim. Read that list for your truck, not the series page.
Real lift ranges, part by part
These are the ranges in Bilstein's application data for parts we carry:
| Vehicle | 5100 (Ride Height Adjustable) | 6112 kit |
|---|---|---|
| Toyota Tacoma 2024-2026 | 24-333207: 1 to 2.5 in on most trims, 1 to 2 in on some | 47-333246: 1 to 2.5 in, 1 to 2 or 2 to 2.5 in on some trims; not for 4WD with leaf rear suspension (our listing) |
| Toyota Tundra 2022-2026 / Sequoia 2023-2026 | 24-329200: Tundra 0 to 2.3 in (4WD) or 0 to 2.4 in (2WD); Sequoia 0 to 2.8 in (4WD) or 0 to 2.6 in (2WD); not for trucks with AVS | 47-329232: Sequoia 2.1 to 3.1 in; Tundra 4WD 0 to 2.2 in on most trims |
| Lexus GX460 2010-2023 / 4Runner 2010-2024 | 24-328258: 0 to 2.5 in | 47-310025: 0 to 2.8 in on the GX460; 0.7 to 3 in on many 4WD 4Runner trims |
| Toyota Tundra 2007-2021 / Sequoia 2008-2022 | 24-232173: 0.875 to 2.3 in | 47-310971: Tundra 0.75 to 2.5 in (4WD) or 1.5 to 3.3 in (2WD); Sequoia 2.1 to 3.3 in (4WD) or 2.6 to 3.3 in (2WD) |
Notice the low end. On the Sequoia and on several 2WD trims the 6112 starts at about 1.5 to 2.6 in, so it is not the part for one of those trucks if you want to stay near stock height. The 5100 (Ride Height Adjustable) starts at 0 on the 2022-on Tundra and Sequoia, the GX460 and the 4Runner.
When the 6112 makes more sense
- You want the bigger shock. Bilstein says the 6112's large 60mm body adds oil capacity and cooling for long-term durability, and the 60mm piston improves comfort and control over rough terrain.
- You are adding weight up front. A steel bumper and winch change what the front spring has to hold. Bilstein lists GX460 kit 47-311039 for 150 to 200 lb of additional front weight, and B12 heavy-load front springs (53-291387) as an option for its Toyota 6112 and 8112 shocks. The 5100 has no spring choice: it uses whatever spring is on the truck.
- Your factory springs are tired. The kit replaces them, so you are not leveling on a spring that has already sagged.
When the 5100 makes more sense
- You want a modest level, starting from stock height. (Not leveling at all? See Bilstein 4600 vs 5100.)
- Your factory springs are healthy and you are not adding front weight.
- You want to replace front and rear shocks in one order. Our 5100 four-shock sets pair the adjustable front with a 0 to 1 in rear, for example the Tundra 2022-2026 set (fronts 24-329200, rears 24-329217) and the 4Runner 2010-2024 set (fronts 24-328258, rears 33-313146).
Matching the rear
Both front parts change the front only. Pick a rear shock built for your rear height (our guide to choosing Bilstein shocks by lift height shows how to read the ranges):
- With a 5100 front, a 5100 rear for 0 to 1 in, or the 5100 rear for your rear lift.
- With a 6112 front, Bilstein's 60mm smooth-body rear, the B8 6100, is the same-size match where it exists: 24-329248 for the Tundra 2022-2026 (0 to 1 in rear lift, without rear air or AVS) and 24-333269 for the Tacoma 2024-2026 (0 to 1.5 in of rear lift; check the rear-suspension note on the product page).
For a lifted front, Bilstein also makes B8 upper control arms that it says correct geometry on lifted trucks and pair with the 5100 (Ride Height Adjustable), 6100 (Ride Height Adjustable), 6112 and 8112. We list the Tundra 2007-2021 control arm kit.
Heavy-duty trucks: 5112 instead
For three-quarter and one-ton trucks, the front leveling kit in Bilstein's catalog is the 5112, not a 6112: two 5100 shocks with two matched coil springs. Examples are 46-302137 for the Ram 2500 4WD with the 6.7L diesel (Bilstein lists 2.3 in of front lift for 2014-2018 and 2 in for 2019-2026) and F4-SE5-C765-H0 for the F-250/F-350 4WD 2005-2016 (2 in). Bilstein recommends an adjustable track bar with both.

FAQ
Is the 6112 just a 5100 with a spring?
No. Bilstein's 6112 uses a 60mm piston and a 2.65 in body; the 5100 (Ride Height Adjustable) uses a 46mm piston and a 2.0 in body. The kit with a 5100 and a spring is the 5112, sold for heavy-duty trucks.
Can I install the 5100 at stock height?
On the 2022-on Tundra and Sequoia, GX460 and 4Runner, Bilstein's range starts at 0 in, so yes. On the 2007-2021 Tundra it starts at 0.875 in and on the 2024-on Tacoma at 0.7 to 1 in. Set the clip in the groove that gives the height you want.
Do I need new rear shocks?
If the rear is not lifted, a rear rated for 0 to 1 in (or stock height) is right. If you add rear springs or blocks, choose the rear for that height.
Which is better for towing?
Bilstein does not rank them for towing. Whichever you pick, a level truck that is not lifted at the rear will still squat under tongue weight, so set the front height with the hitched-up stance in mind and keep the rear at least at stock height.
