Hobbyists chasing consistent lap times will appreciate the Serpent 500259 Carbide Differential Balls. Built for 1/8 scale models, these carbide balls resist abrasion and help the differential turn smoothly under competitive loading.
Carbide is much harder than typical steel, which helps the balls resist pitting and wear. That durability means the diff retains its performance characteristics over more running hours.
Competitive drivers and demanding hobbyists see the clearest gains, as carbide balls support steady power distribution and reduce the need for frequent diff servicing.
