75W-90 Gear Oil

75W-90 is the standard modern grade for manual gearboxes, transaxles and differentials. The right spec matters: gearboxes usually want a GL-4 manual transmission fluid, while hypoid differentials need GL-5 — and limited-slip diffs need an LS oil to stop clutch chatter.We stock Millers XF Premium MTF 75W-90 and Trident Professional MTF 75W-90 for gearboxes, plus competition-grade CRX 75W-90 NT+ and CRX LS 75W-90 NT+ (limited-slip) gear oils.
