UP­PING THE STANCE

Diesel World - - Tech -

Once the align­ment was com­pleted and the lug nuts and been torqued to spec, of course we had to go out for a test drive. As ag­gres­sive as th­ese tires look, you’ll be impressed with how they act on the as­phalt. They don’t give you the heavy steer­ing feel you’d ex­pect and the tread noise is much qui­eter than an­tic­i­pated on the free­way at 75-80 mph. The bal­ance seems to be spot-on as well, which can be a chal­lenge on a big, heavy wheel/tire pack­age, as there is no shimmy or vi­bra­tion on the free­way (thank you Lynn Wood Auto). We do ex­pect to see our fuel mileage drop some due to the added weight and rolling re­sis­tance, but that will re­main to be seen un­til we get some more miles racked up. The tires haven’t had a chance to see the mud just yet, but on a 45-mile snowy morn­ing com­mute be­fore the plow trucks were out they worked ex­tremely well in the snow and icy road con­di­tions.

Next month we’ll get back to some per­for­mance up­grades and will be do­ing some more fuel sys­tem work. We’ll re­place the fuel tank with a larger Titan tank and in­stall a new re­turn­style fuel sump from De­viant Race Parts. We’ve got a lot more to up­grade and re­place af­ter that though, and we’re look­ing for­ward to show­ing you what th­ese trucks are ca­pa­ble of with the right parts and some time in the garage.

 To fin­ish off the lev­el­ing kit, the fac­tory tor­sion keys need to be re­moved and re­placed with the new keys sup­plied by Kryptonite in their Stage 3 kit. To change the keys out you’ll need a spe­cialty tool that will take the preload off so the sup­port...

 This truck gets fin­ished off with the lat­est hy­brid tire tech­nol­ogy from Mickey Thompson: Baja ATZ P3 tires in 285/55R20 size. Th­ese Load Range E 10-ply tires are the per­fect com­pro­mise be­tween an all-ter­rain and a mud-ter­rain pat­tern. This setup...

 The ag­gres­sive side­wall on the Baja ATZ of­fers a great look and matches per­fectly with the Mickey Thompson SD-5 20x9 wheels. The satin-black fin­ish with machined high­lights and sim­ple 5-spoke pat­tern looks killer on this pewter-col­ored truck and will...

 With the front end raised up 2 inches from stock, we have no tire rub is­sues with the 285/55R20 Baja ATZS. But the black wheels prompted us to re­move the not-so-cool chrome trim around the fend­ers. The new stance and wheel/tire combo made this look...

 To com­ple­ment the new front shocks we’ve also re­placed the rear shocks with some Bil­steins from Kryptonite. Th­ese new shocks are valved specif­i­cally for th­ese trucks to of­fer great ride qual­ity with a firm enough ride to im­prove sta­bil­ity while...
