Tuff Torq Industries (TTi) are a unique brand in the automotive aftermarket. Each new addition to the TTi lineup is designed with durability and proven performance gains as their main focus. Typically, you should expect to pay a substantial premium for this type of quality, but through unique manufacturing processes and bulk purchasing these price savings are passed directly onto you, the customer. Tuff Torq Industries (TTi) parts are manufactured from high quality materials and their Quality Control is second to none so you can be confident that not only your product will continue to perform for a long period of time, but that it will be aesthetically pleasing directly out of the box.

Spools are an alternative to a locker for traction and performance enhancement. TTi's high quality mini spools are a favourite of off-road competitors, dirt track racers and drag racers. A differential with a mini spool setup delivers equal power and traction to both left and right-side rear wheels. Spool solutions are less expensive than lockers and weigh less.
The mini spool replaces the original spider gears in an open carrier differential, locking together both axles for even power to both rear tyres!

High quality, heavy duty steel construction
Brand new quality items - don't be fooled by cheap inferior or secondhand mini spools.
Suitable for all 31 spline, 4 pinion Borg Warner with an open centre (non LSD) as fitted to VL Turbo & V8

Torqueline 3.73 Diff Gear Set (Crown Wheel & Pinion)

These are a quality diff gear made by Torqueline Differential. The absolute best "bang for buck" mod you can do to your car. Get faster acceleration without touching your engine!

Torqueline is an Australian owned and operated company and all Torqueline products have been designed and tested right here in Australia and then manufactured overseas to the highest specifications ensuring quality and reliability.

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.

Due to the wide range of housings and gears across the M78 differential range, pinion head may need to be machined down for correct clearance. This is the same for any performance LSD installation.
In some rare cases, diff housing may also require some grinding for clearance.
This is the same for any performance LSD or diff gear installation for these diffs.
