Pro Rocker Shaft Set

Since Toyota has discontinued the sale of its rocker shafts, we have been determined to bring an OEM or better quality shaft back to the market. We've partnered up with the original manufacturer in Japan to bring these shafts that follow all the exact OEM specs for the dimensions of the shaft, and added the touches that make our shafts the best!

The stock Toyota parts have two oiling holes on the bottom of the shafts and very shallow oiling grooves designed to transport oil throughout the rocker arm's bore. Since the stock shafts have proven to be insufficient at properly oiling in high RPM racing or hard duty applications, we're offering our Pro Rocker Shafts that are heat-treated, hard chromed with four large oiling holes as opposed to the two small holes found on the OEM shafts. These guarantee adequate oil delivery at all RPMs and loads. You can be confident that these shafts will be very durable with the thought, design, and treatments we've given them. Follow the guidelines below to determine if you need to replace your rocker shafts:

Subtract the shaft diameter measurement from the rocker arm diameter measurement to receive your oil clearance measurement. If the oil clearance is greater than maximum, replace the rocker arm and/or shaft.


  • Rocker Shaft Diameter: 15.97 mm - 15.99 mm ( 0.6287 - 0.6295 )
  • Standard oil clearance: 0.01 mm - 0.05 mm ( 0.0004" - 0.0020" )
  • Maximum oil clearance: 0.08 mm ( 0.0031" )

NOTE: Avoid the potential hazards of re-using your old worn down or insufficient components and upgrade to our premium rocker shafts. Exhaust shafts contain (1) bolt hole, intake shaft has (2) bolt holes (See illustration above).

5 of 5 Great guys February 17, 2021
Reviewer: Aaron Doll from Hemet, CA United States  
Great guys? I have had to call them in the past to get help deciding what I should do. I really appreciate that they are willing to take the time to talk to you like a smaller company would, but they're large enough to source and improve products based upon their experience. I really appreciate that service and quality. Next item on the list is distributor, I'm not even going to bother looking elsewhere.
