The 3.9 final drive setup from Tomei is an economical way of improving acceleration in the 350Z and G35. Increases available power by 10% per gear, resulting in faster acceleration in every gear. These gears really begin to shine with the larger staggered tire setups prevelant in the Z/G world. Professional installation required. Only for use on 6 speed manual transmission models.
We offer an installation kit that contains all new Nissan OEM bearings and seals, we highly recommend the purchase and use of this install kit. Please note that installing a ring and pinion requires precision setting of the bearing pre-load and clearances and may require install shims to complete the job, these shims are available from your local Nissan dealer in different thicknesses, due to the wide range of shims and the potential variances between different cars we do not include nor offer these shims.
It is highly recommended that an experienced mechanic install this ring and pinion gear set as excessive noise or even catastrophic failure can result from improper installation.
