Bilstein 5100 2.5″ Coilover Lift Kit — 2010-2024 Toyota 4Runner (5th Gen)
Part #: BIL4R10K
Unlock confident control on-road and composed performance off-road with the legendary Bilstein 5100 series. This kit pairs height-adjustable Bilstein 5100 front shocks (assembled with your choice of Old Man Emu (OME) coils) and matched 5100 rears to deliver up to ~2.5″ of front lift, improved body control, and that planted, predictable Bilstein feel your 4Runner deserves.
- Monotube performance: 46Â mm digressive piston keeps damping consistent over washboards, potholes, and highway expansion joints.
- Ride height tuning: Front 5100 shocks feature snap-ring grooves for lift adjustment (pre-set on the lowest clip to work correctly with OME lift coils).
- Fade-free control: High-pressure nitrogen and large oil volume resist heat buildup under repeated hits.
- Durable finish: Corrosion-resistant zinc plating stands up to real-world weather.
- Daily-driver friendly: Taut, controlled handling without the harshness—ideal for commuting, camping, towing, and trail days.
What’s Included
- Front: (2) Bilstein 5100 height-adjustable shocks 24-328258 (supersedes 24-196499), assembled with OME front coils (select spring option from the dropdown).
- Rear: (2) Bilstein 5100 shocks 33-313146, compatible with 0-2″ rear lift. Set of rear lifted coil springs.
- All components as shown in product photos.
Assembly note: We ship the front shocks on the lowest snap-ring setting because the OME coils already add lift. Raising the clip with lift coils can over-lift the front and may cause suspension issues.

Choosing Your Front OME Coils
Pick the front spring rate from the dropdown to match your build. As a rule of thumb:
- Stock weight / light accessories: standard-rate OME coils for best ride height and comfort.
- Medium load (aluminium skids, occasional gear): medium-rate coils maintain height without harshness.
- Heavy load (steel bumper, winch, constant gear): heavy-rate coils keep proper rake and prevent sagging.
Ride, Handling & Tire Fitment
The 5100’s digressive valving firms up initial body motion for flatter cornering and better braking stability, while opening on big hits to avoid harshness. With ~2-2.5″ front lift and 0-2″ rear, many 5th-gen 4Runners run up to 275/70R17 with proper wheel specs; trimming and caster settings vary by wheel offset and tire brand.
Installation Notes
- Alignment required after any suspension lift.
- Torque all hardware at ride height.
- Do not raise the front snap-ring when using lift coils; over-lifting can harm suspension geometry and CVs.
Why Bilstein 5100?
- Proven worldwide: A go-to upgrade for trucks and SUVs for two decades.
- Confidence in the rough: Controlled damping keeps the truck composed on washboard and fire roads.
- OEM-grade durability: Long service life with readily available replacements.
FAQs
Will this kit work with X-REAS?
No. This package is not compatible with factory X-REAS systems. You can probably still install it, but XREAS will be removed.
How much lift should I expect?
Front: up to ~2.5″ depending on coil choice and vehicle weight. Rear: select 0-2″ via the Bilstein rear spring options above.
Do I need an alignment?
Yes—always get a professional alignment after installing suspension components.
Can I move the front snap-ring higher?
Not with lift coils. The shocks ship on the lowest clip because OME coils already add height. Raising the clip with lift coils can over-lift the front and cause issues.
