Elka Suspension
2.5 IFP – Toyota 4Runner 2025 Shock Kit (Extended, 2–3 in. Lift) - Elka 90542
Upgrade your 2025 Toyota 4Runner with the Elka 2.5 IFP shocks, designed as a simple bolt-on upgrade over OEM shocks. Built for 2–3 in. lift setups with aftermarket upper control arms (UCAs) or lift kits, this kit balances daily driving comfort with improved off-road performance.
