    They've had these for many years for other applications (bronco, raptor, JL, universal etc.). The tacoma variant is an application they have been working on for a long time and i'm really interested to see it finally come out.
    In my personal opinion these are one of the best universal IBP shocks on the market (and same sort of design that OME, radflo, ADS etc. use). I've used Fox IBP coilovers on the last 5 solid axle swap trucks i've built/tuned. I think they will struggle as a Tacoma OEM fit product for the front end and get very hot very fast, but i'm interested to see first hand.
    So far Fox OEM fit stuff has been a solid last place for out of the box performance in the blind tests I've been apart of, as tacoma owners we can only hope these are tuned by a new engineer lol.


    The design is fairly simple:

    Their IBP's use an inner sleeve that necks the main piston down to a 2.0. There are 1 way "reed valves" along the cylinder which allow some oil to bypass the main piston depending on which zone it's in. You can tune the valving in the main piston and you can change the port size and placement in the inner cylinder as well as the shim thickness to dial in each zone as you like. For instance if you want the ride zone softer you can increase the hole size, use lighter shims on the cylinder, add holes/valving to lighten it up, or lighten up the main piston which will soften all of it. It's rebound zone is a little weird and i can't get it to behave as nicely as an external bypass, it's pretty much just a ride zone specific bleed hole in the cylinder.

    Very cool tech, but i'm doubtful that it's suited to this application. If anyone gets a set in so-cal i would love to ride in the truck with them to see!

    I've got a bit of experience with these, they're pretty badass. Close friend of mine has the grey Taco that Fox used in the marketing content for these and it works pretty well. Super comfortable on road and through chatter/washboard, but also has alot of capacity for bigger hits, g-outs, whoops. All the OE replacement Fox stuff released in the last couple years is custom tuned for each truck, especially the IBPs. Vehicle specific inner bodies, main stacks, and several weeks of tuning.
