AEM Tru-Time Adjustable Cam Gears

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. These 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.
Product Features:
  • 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.
