RC Speed Secrets YZ-4 hybrid ceramic bearings
Coming from RC Speed Secrets and made for the Yokomo YZ-4 buggy are four new Next Level series hybrid ceramic ball bearing sets. They are available as complete set including gearbox, wheel and steering rack ball race kits but also as separate sets to outfit specific areas of the buggy. The hybrid stainless steel and ceramic bearings are 21 percent lighter than popular ABEC3 ball races, they are highly corrosion resistant and come lightly oiled to reduce natural drivetrain drag and increase efficiency. The complete set includes 22 bearings, the gearbox set comes with two 5x13mm, two 5×10 and six 10x15mm ball races while the wheel hub set utilises six 5x10mm and two 5x13mm ball bearings. Last but not least is the steering rack bearings set consisting of four 5x10x4mm ball races.
