This disc brake adapter is for Toyota Tacomas and early 4Runner models that came with factory drum brakes. Our patent pending adapter enables the rear semifloat axle assembly from a 4th or 5th generation 4Runner, including the disc brake and factory parking brake system, to be bolted onto the stock axle housing.
The adapter set that enables factory Toyota disc brakes to be installed on Toyota Tacomas, early model 4Runners, and Hilux trucks in the international market. This includes the factory Toyota parking brake system making it roadworthy in all 50 US states.
On an industry scale it will make will make Tacomas a viable candidate for overlanding.
The semi float axles can be assembled from all factory Toyota parts. The adapters are in the center of the picture. Gen 1 Tacomas and Gen 3 4Runners use the stock axle shafts from a gen 4 or 5 4runner. The Gen 2 and 3 Tacomas will need to use a custom (longer) axle shaft supplied with the kit. If you want everything new like the picture we can supply it.
Instead of buying all the parts from Toyota, a junkyard axle (buyer beware) can also be used to source 100% of the parts outside of the kit. We recommend replacing the bearings, rotors, and brake pads at a minimum, but you do you.
Two disc brake semi float axle assemblies are ready for install on a Gen 2 Tacoma. You can see the aluminum prototype bolted to the assembly on the left.
These axle shafts are for the Gen 2 and 3 Tacomas. They are longer than the axle shaft of the Gen 4 and 5 4runners. Modeled after the factory axle shaft from the Gen 1 Toyota Sequoia, but ready for the hub bearing from the 4Runners.
All models result in around 2.2 inches per side increase in width. That's around 4.5 inch overall WMS increase. Perfect for those looking for a long travel rear.
This 1995.5 Tacoma has been used as the prototype truck. It's had the disc brake conversion since July 2024 and has several thousand miles of highway, city, and offroad driving. R15 rims also fit over the rear disc brakes.
