CNC Billet Shift Fork 4140 Chromoly Steel suit 1st & 2nd Gear RB25 RB26

Our Billet Steel 4140 Chromoly Steel RB25DET & RB26DETT Billet Shift Fork for 1st & 2nd Gear.

Direct Replacement over the Genuine Factory Shift Fork which is known to fail.

With the best materials and our strict standards for perfect tolerance, we strongly believe our fork is the best on the market.

We have developed this fork for improved shift response, and a more stable shift due to the shift fork having almost 180 degree contact surface area to the shift sleeve, standard shift forks only have 2 contact points on the outer edges to the shift sleeve, meaning more load and wear on the shift fork, this also increases the effort required on the driver to enter 1st and 2nd gear due to minimal contact area on the shift fork to the shift sleeve.

No one is making Chromoly billet shift forks for these transmissions as far as we know, and to top it off, we are nitriding them to give them an even stronger surface finish.
This means, the fork will most likely last a lifetime.

Fitment for ALL RB25DET & RB26DETT Transmissions, including RB30 & VG30 Transmission, Years 1985 until 2001.

“What is Nitriding? A heat treating process that diffuses nitrogen into the surface of a metal to create a case-hardened surface. These processes are most commonly used on low-carbon, low-alloy steels. They are also used on medium and high-carbon steels, titanium, aluminium and molybdenum.”

These are completed, and now currently being nitrided, we should be able to ship by early/mid feb. (we are taking orders now)
