The new fullsize Toyota Tundra with its 5.7L V-8 serves as a solid platform for whatever a pickup truck owner's needs may be. Sporting plenty of oomph to smoke almost any four-wheel-drive pickup off the line, the Tundra simply gets with the program. As such, the rig begs for larger tires. That's why Pro Comp Suspension jumped right on the development of a 6-inch lift kit for the new platform. In the end, Pro Comp would be first to market with two well-thought-out kits-one featuring a simple coilover spacer and the other basically the same kit except with a smooth-riding set of adjustable Pro Comp coilover shocks. We happened to be present the day Dustin Chernoh of DC Customs in Ukiah, California, had his crew begin installing said kit(s) on a local Toyota dealer's truck to see how they compared.

Never one to miss a good opportunity to get the scoop on a new product, we stuck around and watched as the additional 6 inches of clearance took form. Once completed, we took the truck out for a testdrive and even kept in touch with the truck's owner to see how it worked out for him. The results were right in line with what we expected-everything met our expectations, and the truck's owner absolutely loves the new ride. Check out the highlights from the install.

PhotosView Slideshow Here is the Stage 2 Tundra kit from Pro Comp. It differs from the Stage 1 kit because it includes a pair of M-X 2.75 coilover shocks as well as two of Pro Comp's signature MX-6 adjustable rear shocks. We like the fact that the coilovers are valved specifically for the Tundra chassis. The kit also includes high-strength extended steering knuckles. 1. This photo illustrates the gain in beef between the factory steering knuckle and the Pro Comp extended units. Notice the added thickness in key areas where added stress from larger tires would likely cause failure in the stock part. 2. Each Pro Comp kit requires specialized tools such as the spring compressor shown here to complete the installation process. For this reason, we recommend having the work performed by a competent shop with prior lift-kit installation experience rather than attempting the job on your own at home. The factory coil spring must be removed from the factory struts on the Stage 1 kit. This allows installation of the coil-strut spacers. 3. Here you can see the coilover spacer being bolted to the factory coil strut on the budget Stage 1 kit. While this arrangement does allow fitment of larger tires, we really recommend stepping up to the Stage 2 kit for anyone who actually plans to use their Tundra in the dirt. On the Stage 2 kit, wheel travel is increased thanks to a longer front coilover shock. 4. This is the front IFS differential assembly found under the new Tundra. While not exactly what we would call "stout," it does seem to have some extra webbing in key areas. The whole unit must be removed from the truck prior to installation of either version of the kit. Once on the floor, the guys from DC Customs mounted the bracketry from Pro Comp. 5. The differential drop brackets include polyurethane bushings and are powdercoated like the rest of the kit to prevent corrosion. toyota Tundra Pro Comp cutting Process Photo 17135038

6. Here you can see the beginning of the cutting portion of the installation. The Toyota Tundra has a steel crossmember that ties each framerail into one another under the engine. This member must be removed precisely as instructed by Pro Comp. Removing this section allows the front driveshaft to work with the new location of the front differential assembly. This is arguably the hardest part of the installation process. The instructions show very clearly where to cut the member on each side. However, watching the process made us nervous thinking about cutting up a brand-new truck. No pain, no gain, as they say.

Next, it was time to install the new crossmember/differential mounting system. We looked at this part with a very critical eye until we were satisfied that it was strong enough to hold up to the abuse of our readers. Pro Comp did a great job of tying in the structural member so that forces from the lower A-arm pivot points would not affect the front drive system. The bracket itself is made from 3/8-inch-thick ductile steel sheet and features gussets and boxing to provide ample strength. 9. Here you can see the new differential drop-down assembly as it looked just after the lower A-arms were bolted on. Notice how the new structure includes a relocated lower bumpstop mount for the lower A-arms. 10. In this photo, you can see the back side of the differential drop-down assembly. Two stout aft braces are present to negate the added stress of the increased leverage caused by larger tires. Also note the way the new assembly ties into what's left of the existing under-engine crossmember. We think this arrangement is actually stronger than the factory setup. 11. The rear of both Stage 1 and Stage 2 kits includes a pair of 2-inch billet drop blocks to effectively raise the rear of the truck 2 inches over stock. 12. The Pro Comp Stage 1 Tundra kit provides customers with a pair of ES 9000 performance value shocks, which are a fine upgrade, but if tuneability and performance are your goals, go with the Stage 2 kit for the adjustable Pro Comp MX-6 shocks. 13. Pro Comp includes a spacer kit to lower the center driveshaft bearing. This helps prevent driveline vibration and prolongs U-joint life. <strong>Tactics in Traction</strong><br />Pro Comp offers a rear-axle traction-bar setup that virtually eliminates axlewrap and driveline shudder off the line. This is especially effective when towing heavy loads with larger-than-stock tires. We had DC Customs add this to our donor Tundra after the owner had a chance to pull his 24-foot boat without them a couple of times. After seeing the difference it makes, the owner believes there is no other way to go. <strong>Optional Armor</strong><br />Another cool option for the Tundra 6-inch suspension system is the brushed stainless steel skidplate package. The 14-gauge stainless steel sheet material is laser-cut and CNC-formed to fit perfectly with the factory front bumper. A second piece spans the area directly under the front differential and features flared holes for added rigidity. toyota Tundra Pro Comp coilover Shocks Photo 15339362

Which Kit Should You Buy?
When it comes to performance, the Stage 2 kit is the hands-down winner. However, that gain in function comes with a larger price tag. We think the added ride comfort afforded by the Pro Comp coilover shocks makes it worth the extra money, but if you like the factory ride and simply want to fit a 35-inch tire (or you fear taking your new Tundra off the beaten path), you may want to stick with the Stage 1 spacer version. Here you can see the difference between the two front coilover arrangements.

The Stage 2 kit simplifies installation a little bit because you don't have to deal with removing the factory coil springs from the OE strut assemblies, though the increased bulk of the aluminum-bodied coilovers require additional trimming in some areas of the lower A-arm assemblies. So we think the difference in install effort is negated when everything is said and done. The best part of the Pro Comp Tundra system is the fact that you can always go with the Stage 1 kit right off the bat and then upgrade to the Stage 2 kit as desired.
