Rough Country 684198 M1R Reservoir Leveling Struts are front adjustable-height loaded struts built for 2025-2026 Toyota 4Runner models including SR5, Platinum, TRD Sport, and TRD Sport Premium. They address the nose-down factory stance while adding reservoir-equipped damping for drivers who want better control on pavement and rough trails. Multiple spring-perch grooves let you set the ride height without a strut spacer, while the monotube body, remote reservoir, and heavy-duty internal hardware help manage heat, impact, and repeated suspension movement.

Rough Country 684198 Features:

• 46 mm monotube construction uses a 2 in. digressive piston with an external reservoir and internal floating piston to support consistent damping when the suspension is working hard.
• Self-adjusting deflective-disc rebound and compression valving responds to changing road and trail surfaces for a more controlled ride feel.
• Adjustable ride height is built into the strut body with multiple grooves that raise or lower the spring perch to help level the front of the vehicle or add clearance.
• A 2 in. seamless extruded tube and 16 mm centerless-ground, case-hardened, chromed, and super-polished rod give the assembly the strength needed for high-impact use.
• Silver powder-coated finish helps resist rust and corrosion, while vulcanized natural rubber bushings help reduce noise and vibration transfer.
• Bolt-on installation is designed for basic tools and typically takes about 2 to 3 hours with no cutting or welding required.

Includes:

• Front M1R Reservoir loaded leveling struts

Use these front leveling struts when building a newer 4Runner for a leveled stance, added front clearance, and reservoir damping without cutting or welding during installation.

Fits select 2025-2026 Toyota 4Runner SR5, Platinum, TRD Sport, and TRD Sport Premium models. Not for use with a strut spacer. Does not fit models equipped with Adaptive Variable Suspension, Trailhunter models with Old Man Emu suspension, or TRD PRO models with TRD-tuned FOX suspension.
