When installing 3J products whether a single gear to an entire transmission, you can be confident that it has been designed and manufactured to the highest industry standards to ensure fitment and use meet our customers expectations.

To guarantee reliability and optimum performance we recommend assemblies are fitted by a professional mechanic or fitter with a full understanding of the processes involved as so manufacturers tolerances may on occasion require small adjustment on fitments.

This particularly to the fitment of gearkits to donor transmission cases where the only way to ensure the optimisation and reliability of the upgrade is to renew all the consumable items, including bearings, seals and gaskets etc, and we stress highly the importance of using the correct lubricant especially under the conditions of rigorous motorsport. Please ask our sales team fro advice.

It is essential to follow our strict running in period of around 40 to 50 miles of light use. on completion the lubricant must be replaced, as this will remove the microscopic contaminants that have entered the product through this period and which may damage the gear surfaces if left. Following these steps will ensure optimum performance and reliability.

We pride ourselves on providing industry leading technical and post-purchase support, so if you have concerns or require advice on fitment or operation at any stage please call.
