Want a locked differential but don’t know anyone who owns a welder? Secure your place as the local streeto hero overnight with Eight Nine’s proprietary water-based non-Newtonian differential locking formula. DiffWeld works by coating the rotating parts within the differential, acting as a temporary adhesive that actively locks the differential under load.

By premixing DiffWeld with your gear oil in different ratios, the effective ramp angle can be modified to affect the locking characteristics of the differential. Mixing in a 3:1 gear oil to DiffWeld ratio results in a 45/90 ramp angle, which acts like a 1-way locking differential and is perfect for fast road cars. 2:1 gives a 45/65 1.5 way locking action, making it ideal for race cars. For drift cars DiffWeld should be mixed in a 1:1 ratio, resulting in a full-fat 45/45 2-way differential.

NOTE: Highly Limited Quantities Avaliable

Instructions

  1. Remove all previous oil, using brake cleaner to ensure well flushed (removing the diff housing completely is preferred)
  2. Premix Eight Nine DiffWeld with the gear oil of your choice
  3. Carry out 10 minutes of 30 mph speeds to bring the temperature of the differential up, gently.
  4. Once up to temperature, perform 8-12 sharp figure of eights, ensuring full steering lock is achieved. *DO NOT DRIFT DURING THIS PROCESS*
  5. Once the figure of eights are complete, carry out a further 5-minute drive, this time at up to 60mph.
  6. Park the car, and let it fully cool down and cure. the non-Newtonian fluid will now be ‘set’ in place.
  7. Complete!

Making a warranty claim

Proof of purchase receipt showing the date of purchase, proof of mileage at installation, proof of current mileage and invoice of the work undertaken by an independent experienced professional mechanic must be supplied along with the returned products for a warranty claim to be considered. If your vehicle needs to be used whilst your warranty claim is considered replacement parts from the same manufacturer should be purchased through BOFI Racing.
