Redline Heavy Shockproof Gear Oil

This ain’t gear oil—it’s liquid armor. Red Line Heavy ShockProof is the cult-classic, bright-red, freakishly tough gear lube that racers whisper about in the pits. Designed for insane loads, clutch-type differentials, and anything that lives on the edge of mechanical annihilation.

It’s got the film strength of a gorilla grip handshake, cushions gear teeth like a velvet hammer, and keeps temps down even when you’re making horsepower sins.

One quart of “try me.”

If your gears cry under pressure, this is the therapy they need.
