## Description

This product is compact in terms of design, it scores high on the aspect of utility too. This is what makes it worth the buy.

Review: Good quality product, gives confidence in protecting, transmissions and gearboxes.
Review: Needed a replacement for the old fluid in the rear axle of my 2000 f350. This was priced well and the synthetic is a requirement for these axles (especially up here when it gets to -40). Didn't need to use any additive...the limited slip seems to be working fine as it is.
