Shrockworks now officially offers full under-body skids for the 2003-2009 4Runners. There are 4 skids total: Front/Engine, Transmission, Transfer Case/Exhaust, and Gas.
Pricing will be $1,161 for the full set in bare steel, and $1,321 powdercoated. FREE SHIPPING!
I was not able to get installed pictures just yet, but design is VERY similar to that of our 5th Gen 4Runner skids with the exception of a few dimensions and there is no need for an oil filter access plate. Oil Filter is still fully accessible with engine skid installed and there is access for the drain plug as well.
