Rear 2.0 VS IR Shock for 4Runner, FJ Cruiser & GX, 1-3 in.

About this part

Rear 2.0 VS IR Shock, fitment-checked

IR is the internal reservoir — the middle option between no reservoir and a remote one, keeping the extra oil capacity inside the body so there is no hose to route or protect.

Coverage is the Toyota 4Runner from 2003-2024 across thirteen trims, the FJ Cruiser from 2007-2014, the Lexus GX470 from 2003-2009 and the GX460 from 2010-2023, listed for 1-3 in. of lift. The IR designation is worth understanding: ICON builds VS shocks with no reservoir, an internal reservoir or a remote one, and the internal version buys capacity without adding anything outside the body. 4 lb boxed, downloadable install guide.
