Upgrade your 2025 Toyota 4Runner with the Elka 2.5 RESERVOIR shocks, designed for drivers who want to push their vehicle both on-road and off-road. This setup is ideal for vehicles equipped with aftermarket lift kits or upper control arms (UCAs), accommodating lifts between 2–3 inches.

The 2.5 RESERVOIR shocks strike the perfect balance between comfort and control:

• Firm, stable handling for desert and fire roads

• Plush damping compliance over washboard and rough terrain

• Strong progressive resistance for bottom-out protection

• Maximum articulation and traction for rock crawling

Factory preset at 2.5 in. of lift at the front, actual ride height may vary depending on tire and lift kit configuration.

Benefits

• High-performance off-road capability

• Improved comfort and noise reduction in the cabin

• More stable handling and predictable performance

• Reduced front dive during braking and cornering

• Reduced rear bucking and lift

• Increased damping & spring rates for towing or heavy loads
