At Tuff Car Parts, we have been using and recommending Torqueline products for years due to their combination of value, quality and reliability. A great example of this extra attention to detail is the Parkerizing surface protection process carried out during manufacturing. Parkerizing is a method of protecting a steel surface from corrosion and increasing its resistance to wear through the application of a chemical phosphate conversion coating. This phosphate coating process is performed in a chemically balanced hot phosphoric acid solution via an autocatalytic reaction.
The coating material is slightly ingrained into the surface for strong bonding as well as being added onto the surface. This coating as well as protecting the surface from corrosion, also serves as an extreme pressure lubricant during the break in period.
These are brand new high quality items - don't be fooled by cheap inferior or secondhand gearsets that give troubles and have strength issues. Torqueline 3.73 Diff Gear Set Specifications.
