Elka Suspension
2.5 DC Reservoir – Toyota 4Runner 2025 Shock Kit (Extended) - Elka 90540
Upgrade your Toyota 4Runner 2025 with the Elka 2.5 DC Reservoir shocks, designed to enhance off-road capability while improving ride comfort and handling.
These shocks provide the perfect balance between off-road performance and daily driving comfort:
-
Firm, stable handling for desert roads and rough access trails
-
Smooth, responsive damping for washboard surfaces and off-road terrain
-
Progressive end-stroke resistance for added bottom-out protection
-
Maximum articulation and traction for rock crawling
This kit delivers a 2–3 inch lift (depending on tire size and lift kit configuration) and is designed to work with aftermarket upper control arms (UCAs). Preassembled with a 2.5-inch lift, it levels the truck’s front with the rear when a rear lift is installed.
