AEM TRU-TIME Adjustable Cam Gears increase horsepower and torque without having to change the camshaft(s) and are must-have items for engines that are milled, forced induction, high compression and/or utilizing aftermarket competition cams. Our gears enable users to match cam timing with their vehicle's tuning state by advancing or retarding the cam profile in one-degree increments via true laser-etched markings. Precision-cut gear teeth ensure no premature wearing of the belt surface and AEM's anodizing on the gear teeth is lab-test proven as the hardest anodizing process on the market.

AEM TRU-TIME Adjustable Cam Gears are available in a multi-spoke, five-bolt design for most vehicles and our classic full-faced, three-bolt design for select applications. Five-bolt cam gears have an “8” in the suffix (23-8XX), and three-bolt cam gears have a “6” in the suffix (23-6XX).

Legal in California only for racing vehicles which may never be used upon a highway.

  • Increase horsepower and torque without any cam changes and are ideal for heavily modified engines
  • Grade-8, six-point hex bolts stand up to repeated adjustments and feature an integral washer flange for greater load distribution
  • True laser-etched markings on the leading edge of the gear allow for quick, accurate adjustments
  • Hard anodizing on belt surface is lab-tested as the most durable anodizing on the market
  • CNC-machined from 6061-T6 billet aluminum
  • Comprehensive installation instructions, recommended cam gear settings and decals included
  • Manufactured and assembled in the USA
  • For Off-Road use only

The price is for 1 cam gear. If you have a DOHC motor you will need 2.
