Red Line Heavy Shockproof Gear Oil
Red line Heavy shockproof synthetic gear oil offers the ultimate in extreme pressure protection for heavily loaded dog engagement transmission and differentials. This unique product has the film thickness greater than that of a 75W250 oil yet has the low fluidity of a 75W90 oil, effectively giving you the best of both worlds, heavy duty protection without the power sapping viscosity.
- Ideal for non synchro gearboxes and differentials subjected to extreme loads
- Hugely popular in Motorsport applications, particularly drag racing
- Provides the extreme protection of a 75w250 oil but with the relatively low drag of a 75w90 oil
- Cushions gear teeth under extreme pressure and helps prevent teeth breakage
Heavy Shockproof gear oil is ideal for use in drag racing and for off road differentials as well as problem gearboxes and well worn classics. Not recommended for use in synchromesh engagement transmissions.
