Overhead camshafts are found in about every modern-day vehicle. Their job is to open and shut the inlet and exhaust valves at just the right time to permit the motor to go throughout its combustion cycle. The timing of a camshaft is essential to permit the motor to reach best possible power output and efficiency.

When you purchase a standard vehicle, the motors camshaft assembly will be set up by the manufacturer to a predetermined timing value, which in most cases cannot be easily modified. The camshaft timing will typically be setup for reliability rather than peak performance; this means that more power can be gained if the camshaft timing was to be modified. There are a couple of ways that the camshaft timing can be modified, but the easiest and most user-friendly way is through the use of adjustable cam-gears. Adjustable cam-gears can be purchased for a vast number of vehicles and in most cases they are a direct bolt on fit. They come in numerous styles, finishes and colors and can to bring life to an otherwise dull engine bay. The utilization of an adjustable cam gear permits you to advance or retard the timing by small amounts so that the valve timing can be tuned to obtain greater power. In a factory stock engine, the expected power gained by adjusting the timing would usually be very little, but in engine where extensive modifications has been done (e.g. aftermarket camshafts, addition of a turbochargers, milling, porting etc…) then enormous benefits can be expected by fine-tuning the timing. Alternately adjustable cam gears can be used to fine tune the valve timing to increase the fuel economy of your engine as well.

This all being said the proper choice of which adjustable cam gear kit to purchase is very important. There are a number of things to consider before purchasing any kit. First are you just replacing the existing worn or broken gears? Second how much modification has been done to your engine? Finally how much are you willing to spend? These kits vary in price from $100 to $300 and the quality of the kit maybe proportional to the price. The follow is a list of some adjustable cam gears available on the market.

 Buddy Club Racing Cam Gears by Buddy Club $178.00

According to the racing experience, Buddy Club’s engineers developed the super lightweight duralumin cam pulley today’s most popular engines. Lightweight duralumin was overly adopted as the material of both pulley part of an outer, and an inner plate portion to realize super-lightweight body. It is possible to change the engine’s output character by re-adjusting the closing timing of intake valve a below.

By coating with hard almite on the surface, the durability of the pulley has risen dramatically. It can easily be used for the drag racing cars that exceed 1000horse power and 10000RPM. With individual design of IN and EX, the adjustment part of both IN and EX pulley comes to its top when the engine’s TDC for easier valve timing adjustment.

 Fidanza Cam Gear by Fidanza $117.00

Fidanza Adjustable Cam Gears are made from the highest quality 6061 T6 aluminum. They are CNC machined to more exacting tolerances than original gears. The tooth edges are beveled to increase belt life. With twelve degrees (both advance and retard) of laser etched adjustments, you can be assured of proper and precise tuning.

The inner ring of the cam gear is designed for strength, function, and precision. Stainless steel studs are threaded through the backside of the outer gear. The inner gear is then fastened with stainless steel nuts and lock washers. This enables an increase in the amount of torque used to tighten the fasteners, with no risk of stretching to the aluminum threads. All chain drive gears have a 1050 steel outer sprocket. All belt drive cam gears are made from 6061 T6 aluminum.

Tru-Time Adjustable Cam Gears by AEM $109.00

• 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.
• Suggested For Off-Road use only.
