During the Tomei 4AG project, the main focus was aimed at the development of the camshafts which over 10 prototypes were constructed. Through undergoing such criteria as our engine bench tests, actual road tests, and noise assessment, nothing has been compromised until the perfect product had been developed. The best camshafts for the 4AG has been created.

  The pursuit of the optimal profile
The profile of these camshafts were designed to aim for maximum efficiency of the valve opening and closing duration. These PROCAMS were designed with a quicker valve opening time and a gentle closing time to provide stability to the valve seat rings. This lightens the stress applied to the all the surrounding components of the valvetrain and decrease unwanted noises.
@
 Accommodates to high RPM
Each and every profile with varying duration and lift listed below are designed to perform the best during 4,000~10,000 RPMs.
@
  The pursuit of the highest quality product
By utilizing the combination of the best strongest raw materials and the leading CNC camshaft grinding machine in the industry, we have managed to create a camshaft of the highest in quality and accuracy down to the last micron unit.
@
  Compatible with inner shim kit
The PROCAMS are not compatible with a stock head assembly. Since we are still currently developing inner shim kits for the 4AG, we would recommend the set made by TRD.
