Though short lived, the Toyota T100 was a good midsized truck that had a lot going for it. And thanks to guys like Allen Yost who have taken the stock design to the extreme, the T100 has proven itself to be a great off-road platform.
Of course, Yost, a 37-year-old electronics engineer from San Diego, CA did have a little help in transforming the 1996 Toyota T100 from stock into what rides the desert today. He got it from the crew at GR Fabrications of Chula Vista, CA.
GR Fabrications, who is fronted by Glenn Robles, used a GR Fabrications A-arm front suspension, one that was designed by Dan Vaughn Design and Yost, as a basis for the front suspension. It is nickel-plated and utilizes GR Fabrications / Dan Vaughn Design spindles and Desert Specialties hubs. A Howe steering box and pump keeps the Toyota pointed in whatever direction Yost wants to go.
The shocks are Eibach spring-equipped 10-inch Radflo 2.5 coil overs, 12-inch Radflo 3.0 3-tube bypass and backed up with Radflo 2-inch bump stops. Wheel travel is a full 18-inches of the good stuff.
The 4-link rear suspension is again a nickel-plated GR Fabrications/ Dan Vaughn Design work of art. And again a set of Eibach springs grace the Radflo 2.5 coil-overs but this time the 16-inch Radflo 3.0 bypass shocks have 5-tubes and the Radflo bump stops are 4-inchers. This time there’s a full 26-inches of wheel travel.
The rearend in question is a Schreiner Enterprises 9-Inch Full Floater housing with race center and back brace, Schreiner 2.5 Hubs, and 40-spline axles. A Strange Engineering case with Richmond 5:00 gears and spool provides the teeth, while it was Driveshaft Pro San Diego, CA who built the shaft. When all is said and done, the wheelbase is now 125-inches with a track width of 92.
A remote Hydrobooster reworked by Vanco pushes fluid to the set of Wilwood 6-piston Billet calipers with 14-inch Wilwood rotors that adorn the front system while Wilwood 4-piston Dynalites with 14-inch rotors are attached to the rearend housing.
It took a little whittling on the Hannemann fiberglass fenders and bedsides, but Yost was able to get the 37-inch BFGoodrich Projects to fit. They are mounted to Robby Gordon 17-inch Bead lock wheels.
The full cage system also cradles the 4.7L Toyota engine. Basically stock, items such as a BTI Performance “Cyclone” air cleaner and an Eric Anderson/ILK Fabrications cat back exhaust system help to get the juices flowing. The exhaust system includes a Spintech X-pipe and dual Spintech Pro Street mufflers.
Wanting to get every one of the estimated 300-horsepower to the rearend, Yost upgraded the Toyota Tundra 6-speed auto trans with an ITP valve body and 3,000rpm stall converter. A Derale heat-sink type trans cooler keeps everything cool.
As stated, Yost had to modify the Hannemann fiberglass to clear the 37’s, but he also shortened the bedsides 12-inches, too. He then had Luis in Lemon Grove CA apply the PPG Lamborghini Grigio Avlon paint. A 20-inch Baja Designs OnX LED light bar with yellow lenses adorns the front push bar while two 20-inch BD OnX bars are mounted on the roof over the windshield.
With tubes going everywhere, that cage that surrounds the T100 is prevalent inside the cab too. It safely encases the occupants, as does the MasterCraft Baja RS seats and Crow harnesses. The dash and gauge cluster are stock, but a refrigerator equipped custom center console certainly is not. To be fair, it also has a PCI race radio, intercom unit, a cluster of switches a pair of Auto Meter gauges and a Winters shifter.
A Momo steering wheel enhances the stock dash and gauge cluster while a Lowrance GPS unit and IPAD running LeadNav keeps Yost on the straight and narrow. Yost rigged his own custom fresh air system.
Like we said earlier, the mid-sized T100’s never quite got a hold on the market, but it was a good effort by Toyota that has been made even better by Yost and his buddies. This truck is a full-on pre-runner that shows no sign of future termination.
