Description:
Unorthodox Racing's (UR) single pair of Exhaust cam gear/s are perfection in craftsmanship. Each gear is CAD designed and CNC machined from U.S. aluminum. They are the lightest and safest gears on the market. UR gears were the first 5 bolt design. Each gear is adjustable in one degree steps to a maximum of + or - 10 degrees (advance or retard) which is more than you will ever need. The timing marks are engraved and accurate to within one (1) minute of a degree (there are 60 minutes in a degree)! No need to send our gears to the machine shop to be re-indexed like other brands that are off as much as 1 to 2 degrees!
The fit of the inner and outer sections is the most critical part of cam gear machining. Any looseness, not the normal sliding movement but side to side, will cause bolts to come loose, no matter how much you tighten. UR gears fit tight, every time, so our gears will not come loose. Timing tooth shape is also extremely important for timing accuracy, long term reliability of the gear teeth and the timing belt. UR tooth profiles match or are better than original gears.
UR gears are hard black anodized to prevent wear from the timing belt. The black finish is so you can see the engraved timing marks better. Horsepower gains vary depending on what you've done to your engine. Gains from 5 to 20 horsepower can easily be seen. We have recommended settings in the instructions. We also suggest going to a dyno for fine tuning.
Highlighted Points
• The highest HP / torque gains on stock or aftermarket cams.
• The first 5-bolt pattern for secure slip-free adjustment.
• The easiest to read timing marks.
• The most fine adjust ability in increments down to 1/4 of a degree.
• The most total adjust ability + or - 10 degrees.
• Accurate within 1 minute of a degree (60 minutes in a degree).
• Tooth profile identical to or better than the original gear/s.
• Hard-Coat black anodized for unmatched durability.
• CAD designed & CNC'd machined from U.S. made aluminum forgings
• Made In The USA

Unorthodox Racing cam gears are adjustable by +/- 10º (advance/retard) and accurate to within 1 minute of a degree! Because of their design, Ultra Time Street sprockets are lighter than the original OEM gears.
Unorthodox Racing (“UR”) was founded early in 1996 by performance enthusiasts that had spent almost a decade hands on tweaking and tuning various American muscle cars. By the early 90’s it was clear a new automotive era was beginning to debut with high performance small displacement engines. Work began on what would be the first product line, underdrive pulleys, in late 1993. Slowly over the next 3 years the pulleys were tested and tweaked. The most important part of this plan was their strict policy of only making products that did what they said they would, fit like they said they would, looked like automotive artwork and would last the lifetime of the vehicle. UR was quickly accepted by enthusiasts, racers and tuners alike as a supplier they could trust to make only the highest quality, uncompromising performance products. Combined there have been billion miles driven using Unorthodox Ultra and Tuner Series products with only the highest satisfaction.

Q: Do cam gears come individually?
A: Cam gears are sold individually unless otherwise noted. Depending on whether your vehicle is a single overhead cam (SOHC) or a dual overhead cam (DOHC), you will need one or two cam gears.
Q: What do cam gears do? Why buy cam gears?
A: Cam gears are used by many for a reliable, precise and affordable method of fine-tuning the action of the valves. This complements the installation of performance add-ons such as headers, camshafts, intakes or specialty milling work on built motors. Cam gears are often used for adjusting the timing degree of newly installed camshafts in your motor. You want to adjust cam timing to make the maximum power with your motor. If you buy aftermarket cam shafts, you cannot fine tune them to make more power if you don't have a set of adjustable cam gears.
Q: How do you install cam gears?
A: Installation should be left to the pros on this one since timing will be involved. If you plan on doing it yourself, removal of the upper timing belt cover will need to be done to reveal the cam gears. The valve cover along with the camshafts will need to be removed. Once this is done, replace the factory cam gears with your new ones and reinstall onto your camshaft. Make sure when you remove and reinstall the camshafts and cam gears they are at top dead center (TDC). Replace everything as you removed them and re-time your vehicle.
