Nissan GTR 4.625 Ring and Pinion (Neat F160, Front)

This Nissan GTR 4.625 Ring and Pinion is a Neat F160 crown wheel and pinion set built for R32, R33, and R34 GTR front differentials. Specifically, Neat manufactures it from stronger EN36C case-hardened steel. As a result, it then profile grinds the set after heat treatment for a tighter, more consistent gear mesh than a standard replacement set.

Specifications

  • Ratio: 4.625 (37:8 tooth count)
  • Material: EN36C case-hardened steel
  • Manufacturing: Profile ground after heat treatment
  • Spline Cutting: Hobbed for added strength
  • Pinion Nut Thread: Ground for a precise fit
  • Position: Front Differential

In particular, Neat cuts the splines by hobbing, which produces a stronger spline than other cutting methods. Overall, the result is a gear set built to handle sustained high-RPM use. It avoids the wear issues that come with a lower-spec replacement set under hard driving.

GTR 4.625 Ring and Pinion Fitment

This set suits R32, R33, and R34 GTR front differentials specifically. In particular, the 4.625 ratio favours faster acceleration over top speed, making it a common choice for street and strip builds. Additionally, a matching rear 4.625 ratio set is available in either Neat or genuine Nissan. So, enquire with us for pricing if you need both ends to match, since front and rear ratios should be paired on a GTR driveline for correct handling and drivetrain balance.

Why Choose Neat

Neat builds its GTR gear sets from upgraded EN36C steel rather than a standard replacement-grade material. Combined with profile grinding after heat treatment and hobbed splines, this gives you a gear set built to handle harder use than the factory part. As a result, that makes it a popular choice for GTR owners pushing beyond stock power levels. A worn or weak factory gear set is often the first thing to fail once you start pushing more power through the driveline.
