Ever have an engine come apart at high RPM? Well, we haven't. At least, not due to rotating assembly vibrations. We've partnered with the biggest name in the industry yet again to release an 800+ HP capable harmonic balancer for all 3UR-FE and 3UR-FBE 5.7 liter "big block Toyota" engines. That includes Sequoia, Tundra, Land Cruiser, and LX570
Please note this does not work with 6 rib belt 1UR engines. We are still working on a solution for the small block 4.6.
We now stock a special 7" overdrive diameter pulley for high boost applications with a supercharger! A larger pulley while keeping the included blower pulley the same size will spin the blower faster and make more boost. WE STRONGLY RECOMMEND NOT DOING THIS UNLESS YOU HAVE A BUILT ENGINE WITH AFTERMARKET RODS AND A SOLID TUNE.
