Blazing A New Trail

Post by forum-guru » Tue Oct 10, 2017 3:22 am

When GM phased out the S-10 Blazer they replaced it with the Trailblazer. Despite body-on-frame construction, a strong engine, and a solid rear axle, the Trailblazer has even less aftermarket support than the S-10 Blazer it replaces.

They picked up the Trailblazer for cheap and intended to modify it from the start. Power comes from the factory Vortec 4200 inline six-cylinder that sends 275 hp to a 4L60E that received an auxiliary cooler and fan to keep it running cool. The temps are monitored in a gauge where the factory transfer case dial used to reside. That knob wasn’t needed once the dual transfer cases were added. The planetary from an NP241 is mated to an NP241 with a 32-spline output shaft and slip yoke eliminator with a Box 4 Rocks adapter.

The 4.2L Vortec six-cylinder was treated to a custom computer tune and a 3-inch exhaust. Otherwise it was left stock for reliability. Also visible are the four solenoids used for powering the front winch.

From there things get really interesting. The factory suspension and axles were sent to the metal recyclers and 1-ton axles and leaf springs were used in their place. Why leaf springs? All four corners are sprung by 52-inch Chevy springs that can be sourced from nearly any junkyard and work in conjunction with Rancho 9000 shocks. The springs move the axles out 6 inches at each end, which helps fit the 40-inch Nitto Mud Grapplers on Raceline Monster aluminum beadlock rims.

In order to live with the 103:1 crawl ratio and 40-inch Nittos, only 1-ton axles would do. The rear axle is an ’02 14-bolt that has factory disc brakes and was upgraded with 4.56 gears and a Detroit Locker from a CUCV truck under the Blue Torch diff cover. The front axle is a high pinion Dana 60 from a Ford. It has been fortified with 4.56 gears, a Yukon Spartan locker, Reid Racing knuckles, 35-spline Yukon chromoly axleshafts, Warn hubs, and a Blue Torch diff cover. Steering comes from a Toyota steering box that was tapped to work with a PSC hydraulic ram.

Added sliders from Trail Gear to protect the body. The front bumper was built to house a 10,000-pound winch and recovery shackles, while the rear holds a full-size spare and KC backup lamps. Built the rear bumper pivots with a shackle hanger kit he had lying around, and the whole thing folds down to access the cargo area. Inside he has a full cage and straps to hold down the Hi-Lift, spare driveshaft, CO2 tank, and spare parts and tools.

The end result definitely achieved desire for a unique vehicle and illustrates that you don’t need to break the bank in order to have a capable wheeling vehicle.
