Bilstein/OME 2.5″ 5100 Assembled Coilover Lift Kit for 2010-2024 Toyota 4Runner

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: 46 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.
