RSB Racing Oil Pump Gears replace the discontinued OEM straight cut gears trusted for 35 years across nearly every 4G63T engine. These upgraded gears deliver 20% greater strength while eliminating catastrophic failure risk through an integrated stub shaft design that prevents separation.
Extensively tested on Richard's personal 4G63T-powered MR-2, these gears maintain consistent oil pressure from idle through 8400 RPM with minimal variance. They strike the ideal balance between the weaker helical alternatives and premium-priced competitors, offering proven reliability and performance for serious builds.
