Toyota Dirty 30 Axle & Birfield Kit
With larger tires and more horsepower being used on the trails these days, upgrades to your axle are more critical than ever. In a Toyota, one of the common failures are the stock 27-spline birfields and axles. The solution to this problem is Trail Gear's Longfield™ 30-Spline 4340 Chromoly Super Set. These birfields and axles will get you to wherever you need to go and give you confidence and peace of mind to run any trail.
The Longfield™ birfields are made out of 100% chromoly and are precision polished to remove any imperfections that may cause stress risers. The Longfield™ birfield housing is made out of forged 4340 chromoly steel. The axle shafts are also made out of 4340 chromoly steel. The internals of our Longfield™ birfields are made out of vacuum arc remelted 4340 chromoly steel and then dual heat-treated for superior strength.
Trail Gear understands that once you upgrade your axles, the next weak link is your hub gears, so they include the Chromoly Inner and Outer Hub Gears and Creeper Drive Flanges at no additional cost! This will give you the confidence that your front axle will stand up to any trail you wish to run, and will save you $365.40 over purchasing them separately.
These parts have undergone years of extensive in-house and field testing. We are so confident with the Longfield™ 30-Spline 4340 Chromoly Super Set that Trail Gear offers this kit with the No Questions Asked Lifetime warranty. This warranty has no limitations and is not limited by the size of the tires on your rig.
This item fits Toyota FJ60 and FJ62 Landcruisers with 30 spline shafts.
