URD Exhaust Cam Gears 4.0L 1GR-FE V6

(2 customer reviews)


These are the same cam gears we have been shipping in our UCON-EMS kits for many years. They replace the stock exhaust cam gears found on the original single VVTi 1GR-FE 4.0L engine found in the 03-09 4Runner, 05-15 Tacoma, 07-09 FJ Cruiser, and the 05-09 Tundra as well as many other vehicles found in foreign markets.

The URD Cam Gears modify the timing of the exhaust cam to allow for better cylinder emptying on the exhaust stroke, which in turn allows for better cylinder filling on the intake stroke with less hot end gas hanging around to heat up the incoming cylinder charge. This allows for great flow through the engine and allows for more aggressive spark timing. The Cam Gears work great for Normally Aspirated and Supercharged applications.

Made in the USA by an aerospace company specializing in precision gears for aircraft and spacecraft and are properly ground and heat-treated for trouble-free service in your engine.

Not recommended for Turbos or other applications causing high exhaust pressure.  Not recommended for aftermarket camshafts.

    Awesome product makes truck run like a champ. Break cam bolts first then set timing marks.

    The exhaust cam gears have drastically improved the overall throttle response of my vehicle and the engine torque. The hardest part of the installation was loosening the existing sprocket bolts. Good modification for the price. Thanks.
