Longfield 27-Spline 4340 Chromoly Super Set 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 our 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 100.0 Percemt 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.
