Neo Synthetics 75W90 RHD Gear Oil, Quart

Shifts smoother than butter in my 92 Galant VR4. I'll be adding it to my transfer case and rear differential soon. I'm OCD and I like the shape of the bottle, easy to get every last drop. Comes as four, 1 quart bottles.

I've used this NEO gear lube in my Mercruiser Alpha boat Sterndrive for 18 yrs. This is an extreme application where up to 250 engine HP is delivered through two spiral bevel gear sets, the final drive having a pinion pitch line of < 2.5" diameter with an extremely high pitch line velocity. I've rebuilt this drive three times due to collisions with rocks. The spiral bevel gear surfaces are perfect after 18 years. I change the lube every two years, with minimal swarf on the drain plug magnet. There are five Timken tapered cone bearings in this drive. The race surfaces are always in perfect condition. This drive also has a dog clutch which still looks new.I installed NEO RHD in my '99 Dodge Durango rear differential. Also 18 yrs later no problemsIf you are a boater, racer, or just serious about maintaining your gearbox, this lube is worth the price.
