The long-awaited Nissan R200 200mm 3.90 Ratio Differential Final Drive Gear Set suit most Nissan's which run the R200 IRS Differential.
Commonly found in the Nissan Skyline, Silvia , Cefiro , Laurel and so on.
Commonly found in the Nissan Skyline, Silvia , Cefiro , Laurel and so on.
The long ratio we designed is great for high powered vehicles running a 6 Speed Transmission, Dual Clutch Transmissions and or even a 2 Speed Powerglide Automatic.
This unit also has undergone a special hardening process to ensure the gears can last long under extreme conditions, we suggest this to be installed and shimmed by a competent differential builder.
We have made the crown wheel bolt's suit 12x1.25mm pitch bolts, this is also compatible with 13mm Limited Slip Differential's, since the locating point is from the LSD and machine work on the Crown Wheel, do not be afraid of 12mm bolt's in the 13mm LSD, the bolts are only doing the clamping work, the accuracy of the LSD and Crown Wheel machine work is what determines the "runout" on the LSD/Gears.

We now offer Isotropic Superfinishing on all our Speedtek Products.
(This process will increase the time from when we could dispatch the kit, please email us if you have any questions)
Superfinishing is a metalworking process that improves surface finish and workpiece geometry. This is achieved by removing just the thin amorphous surface layer left by the last process with an abrasive stone to grind the gears and other parts ; this layer is usually about 1 μm in magnitude. Superfinishing, unlike polishing which produces a mirror finish, creates a cross-hatch pattern on the workpiece.
Advantages of superfinishing include; increasing part life, decreasing wear, closer tolerances, higher load bearing surfaces, better sealing capabilities, and elimination of a break in period.
