Project axle upgrade. The rear axle on this 1985 Toyota 4runner is off a newer V6 model which is 3" wider and thicker then the stock 85 axle that was under there before. This axle housing in the picture has been heavily modified to accommodate the style of off roading that this truck was meant for (ROCK CRAWLING). The housing had to be prepped to fit the Toyota TRD e-locker setup. To do this we needed a fancy jig that we built (for the new stud holes for the e- locker) , a torch, welder, grinder, air hammer and some brain power. Then after all that was said and done it was time to build that housing to take on the rocks. Armor from Blue Torch Fab was welded into place in order to protect that differential from the trail abuse. A fancy, but functional Ballistics Fab filler/inspection cap was installed for the ease of inspecting the gears and filling differential with gear oil.
Once the axle housing was all welded, painted and new seals where installed it was time to drop in the new Nitro 5:29 gears that just came back from Bobby Longs. The gears where at Bobby Longs getting CRYO* treated (BEEFY/STRONG). After the axle was done and ready we started the suspension calibration. This is the fun part because there is math incorporated in order to get the correct measurements of the full droop and the full up travel of the leafs. The leaf springs where disassembled so that there was very little resistance in order to allow for the trial of our calculations. This is very important because if you don't get it right the 35"- 37" tires that will be mounted will end up crushing the fender wells during the up travel of the suspension. NOT GOOD FOR THE BODY! Once we figured out the exact location of the axle and springs it was time to fab up our new leaf spring hangers. These are supper beefy and keep the springs safe from any rock bashing that may happen out on the trail. Up next is the front axle!! Stay tuned for more awesomeness!

The process has a wide range of applications from industrial tooling to improvement of musical signal transmission. Some of the benefits of cryogenic treatment include longer part life, less failure due to cracking, improved thermal properties, better electrical properties including less electrical resistance, reduced coefficient of friction, less creep and walk, improved flatness, and easier machining.
