New product designed as an intermediate viscosity providing additional film strength over a 75W90, yet less drag than a 75W140
Developed with support from Red Line-sponsored racing team and project cars, provides improved limited-slip operation under extreme loads and differential temperature
Offers gear noise reduction over 75W90, avoiding a significant jump in viscosity to 75W140 when troubleshooting noisy gear sets
Popular in many sports car applications as well as light trucks (Chevy 1500 Silverado, Tahoe, etc.)
Contains additional friction modifiers for suitability with clutch-type limited-slip differentials - for most LSDs, no additional friction modifiers are required
This product is not designed for use in most manual transmissions or transaxles, since the extreme slipperiness may cause synchronizer mesh issues that lead to shifting problems
