DIFFERENTIAL FRICTION MODIFIER & BREAK-IN ADDITIVE- is a friction modifier designed to reduce limited-slip noise and to aid the proper break-in of any differential. This can be added to any gear oil to reduce temperature during break-in and prevent gear softening. Replaces manufacturers' limited-slip additives. Can be used to perfectly tune a limited-slip unit. Red Line 75W90 and 80W140 Gear Oils already contain this additive.

Red Line 10W40: Best choice for engines that typically run high oil temperature or for engines in daily-driven vehicles regularly operated in hot weather. Great for medium and heavy duty gasoline engines in trucks. Best choice for high-performance engines that see street/strip or track activity. Features a thicker oil film at operating temperature than a petro-based 20W-50.

Red Line 10W30: Best all-weather viscosity grade for gasoline engines in cars and light trucks that are driven on the street on a daily basis. Reduces turbo lag and provides more power and economy while providing thicker bearing oil films at operating temperature than a petroleum 10W-40. Best all-round, synthetic oil for stock or slightly modified engines in high- performance cars that are street-driven. Best choice to replace a 5W-30 or 10W-30, petroleum-based or other-brand synthetic oil if maximum durability is preferred. Acceptable for engines that are occasionally operated in extreme cold weather.

75W90NS - recommended for manual transmissions and non-limited-slip transaxles that recommend 140 WT oils. Can be used in racing limited-slip units to increase lockup and reduce wheel spin. Street-driven rear-wheel drive cars should use regular Red Line 75W90 or 80W140.

SHOCKPROOF^TM GEAR OIL - recommended for heavily -loaded racing differentials and transmissions which see shock-loading. ShockProof contains a unique solid dispersion which cushions gear teeth to help prevent tooth breakage and allows the use of lower viscosities. Available as SuperLight, LightWeight, and Heavy grades.

Red Line Synthetic CV-2 Grease - possesses a very high melting point, excellent water washout resistance and superior antiwear which makes it excellent for high-temperatures and extreme loads. CV-2 contains an organic moly and is for wheel bearings, high-angle and conventional CV-joints, chassis lubrication and high-temperature, high-speed industrial equipment.

Red Line® Power Steering Fluid- provides much improved wear protection and resists thermal breakdown. Provides continued high pump output at high temperatures and resists evaporation and foaming at high temperatures. Suitable in most power steering units.

WaterWetter® Supercoolant- is a unique wetting agent for cooling systems which reduces coolant temperatures by as much as 30°F. This liquid product can be used to provide rust and corrosion protection in plain water for racing engines, which provides much better heat transfer properties than glycol-based antifreeze. Or it can be added to new or used antifreeze to improve the heat transfer of ethylene and propylene glycol systems. Designed for modern aluminum, cast iron, copper, brass, and bronze systems.
