Optimize your engine quickly and easily with a new SpeedFactory Racing D15/D16 Adjustable Cam Gear featuring our EZ-Dial Adjuster. With a cam timing adjustment range of +/- 10 degrees, you can dial in correct cam timing and/or tailor the power curve as desired. This is a must-have for performance engines using aftermarket camshafts or that have a cylinder head or block that has been milled or decked.  

Gone are the days of frustration trying to precisely set cam timing and repeatedly bumping the cam too far or not far enough with cumbersome movements made using the cam gear mounting bolt or crank pulley bolt - our new EZ-Dial 6mm hex key adjuster and amplified timing scale allows easy, smooth, and precise adjustments like never before!

Belt tooth profile accuracy and axial & radial runout testing showed a 25-50% improvement over OEM and competitor offerings, and FEA design process ensures a strong, balanced gear that runs true at 12k+ rpm. 

  • Precision CNC machined from 6061-T6 billet aluminum
  • Black Hard Anodized finish for maximum durability
  • Laser-etched SpeedFactory Racing logo
  • Red EZ-Dial Timing Adjuster makes precision timing adjustments quick and easy
  • True laser-etched directional markings & amplified +/-10* vernier timing scale for easy to read, accurate adjustments

NOTE: Gear center ID’s may be honed post-anodizing for a precise fit onto the cam snout OD. You will also need a Honda B-Series woodruff key to complete the cam gear installation, OEM Part # 90741-657-000. 

 

INSTALLATION NOTES:

1. The OEM cam gear has the Woodruff key built-in to the gear. You must use an OEM Honda Woodruff Key (Honda Part # 90741-657-000) with our adjustable cam gear (AVAILABLE HERE).

2. NEVER USE AN IMPACT GUN TO INSTALL THE CAM GEAR!!! Use a properly calibrated torque wrench and torque cam gear bolt to 23ft-lbs for aftermarket chilled cast performance camshaft (27ft-lbs for OEM camshaft). Use a small drop of removable thread locker like BLUE Loctite on the bolt.

3. Reinstall timing belt and make sure mechanical timing is correct with the engine at the TDC position.

4. You can now use the EZ-Dial Adjuster to degree in your camshaft to the desired settings.

The <-A and R-> markings at the top of the outer ring tell you that when the center & cam is rotated in the direction of the A or R arrow, you are advancing or retarding the cam. The number of degrees from zero in that direction will be read directly across from the <-A or R-> markings on the opposite side of the cam gear.

When finished, tighten the (4) 5mm Allen head locking bolts to 18 ft-lbs using a small drop of removable thread locker like BLUE Loctite on the bolts.

Comfortable, cooling, and OEKO-TEX certified, it’s a great way to refresh any mattress.
This 3-inch mattress topper instantly upgraded my bed with a softer, cooler, and more supportive feel. The bamboo-viscose fabric is noticeably breathable, helping regulate heat throughout the night—great for hot sleepers. The 1200GSM down-alternative fill adds plush, cloud-like cushioning while still offering balanced support for the back and shoulders. It fits securely with the deep pockets and stays in place even when turning. After allowing it to fully expand, the topper fluffs up beautifully. Comfortable, cooling, and OEKO-TEX certified, it’s a great way to refresh any mattress.

Great upgrade for a rental apartment mattress
The mattress in my rental place is firm to the point where it almost feels unfinished. Instead of replacing it, I decided to try adding this topper. It made an immediate difference in the way the bed feels when I sit or lie down. There’s a nice cushioned layer that softens that “flat” feeling but still holds its shape. Another thing I noticed is how breathable it is. I expected thick padding to feel warm, but the airflow here feels better than the original mattress surface. Even after moving around, it never felt heavy or stuffy.

Soft and Comfortable Topper
I got this bamboo mattress topper for a small single bed we keep in our guest room, but I ended up testing it out myself first. The material feels soft and breathable, which is nice because that room can get a little warm in the afternoons. It adds a good amount of cushioning without making the bed too soft. After a couple of nights, my back actually felt better compared to the old mattress alone. I also appreciate that it’s machine washable, because our guest room sometimes doubles as a nap spot for my son after swim class, and spills happen. It dried pretty quickly in the dryer and kept its shape. Overall, it made the bed feel much more comfortable and fresh.

Added comfort for someone working night shifts
I work odd hours, so my sleep schedule is all over the place. My mattress has always felt a bit too stiff after long shifts, so I got this topper hoping it would help me relax faster. It really changed the overall feel of the bed. The padding has a cushioned lift that makes lying down feel smoother, especially around the shoulders and lower back. Instead of feeling like I’m dropping onto a firm surface, there’s a soft layer that evens out the pressure. What surprised me most is how light the surface feels. Even after staying in one position, it never gets stuffy or heavy. The airflow makes a difference when your body is trying to wind down after work. The fitted pocket also stays tight around the mattress, so nothing shifts when I move. I can stretch out without worrying about the topper sliding off.

Good option for softening a college apartment bed
I moved into a college apartment where the bed felt like it belonged in a dorm from years ago—flat and stiff. Instead of dealing with it, I tried this topper, and it added a cushiony layer right away. The surface feels much more forgiving when I fall onto the bed after studying or hanging out with friends. It has just enough padding to take away that board-like feeling without making the bed sag. Another thing I noticed is how breathable it is. I expected something this thick to feel warm, but it actually stays cool even if I stay on one side for a long stretch.
