RED LINE HEAVY SHOCKPROOF 75W250 BOX OIL 1Lts

Higher film thickness than SAE 75W250, but lower fluid friction than 75W90
For heavily loaded racing differentials and transmissions, problematic gearboxes
Many high performance racing applications such as Sprint/Midget/Dirt Late Model differentials, Detroit Lockers and spools, NHRA Top Fuel and Funny Car rear ends
Not recommended for most synchronized applications due to extreme slipperiness of the product

Unique lubricant with microscopic solid particles that offers low resistance and high protection
Relatively low viscosity, but cushions gear teeth under extreme pressure
Helps prevent tooth breakage, resists detachment
Avoid use with pumps, chillers and filters as the unique media and affinity for metal may cause clogging.
Designed for wet sump transmissions and differentials with splash lubrication
