One fatal flaw of the Duratec / MZR line since day one has been the complete lack of keys/dowels/locating devices on all of the cam timing components. While we're sure eliminating them made it far easier for robots to assemble the motors in production (and scared away shade tree mechanics from working on them), the possibility of slippage ensured disastrous results. The potential for slippage, while remote on a stone-stock-untouched-grocery-getter, was much more a threat on the modified, high RPM motors us folks like to build. 

Massive has stepped in and now offers a complete line up of keyed crank shafts and companion timing chain drive gears!!!

 

Cranks: 

We started with  NEW (high quality professionally remanufactured in the case of the 2.3 Ranger and 2.5 Dura - new from ford no longer available ) OEM crankshafts and added a proper key way to allow the timing chain drive gear to be positively locked to the crank in the event the crank pulley bolt should come loose. This will prevent COSTLY damage to your engine! Use with our keyed chain drive pulley.

2.0 Duratec - Factory FORGED Unit

2.3 Ecoboost - Factory FORGED Unit

2.3 Mazda DISI - Factory FORGED Unit

 

Gears: 

 

We started with A brand new Ford ? Mazda chain drive gear and EDM cut a proper keyway to allow the timing chain drive gear to be positively locked to the crank in the event the crank pulley bolt should come loose. This will prevent COSTLY damage to your engine! Use with our keyed crankshaft. Includes key.

We've always felt the cam gears don't need a key way or dowel - Allowing them to orbit whilst installing the timing chain is a must. Additionally, there is far less chance for slippage, reuse the now unnecessary diamond washers from the crank pulley on them if you please, run some loc-tite as well. 


Keyed gears and cranks are sold seperately

Lightweight oil that fits into a simple routine
I started using this oil as part of my regular skincare routine, mainly applying it to areas like my arms and face after showering. The texture feels light and spreads easily without leaving a heavy residue. I noticed it absorbs fairly quickly, which makes it convenient for daily use. It also has a mild scent that is not overwhelming. I like that it includes plant based ingredients, and it leaves my skin feeling soft after application.

Amazing!!
Scent: Unscented, Size: 1.85 Fl Oz (Pack of 1), Scent: Unscented, Size: 1.85 Fl Oz (Pack of 1)
Amazing product! I have a hormone imbalance and am prone to ingrown hairs, pustules, and very coarse hair on my chin, jawline, and neck. Since using this product, my ingrown hairs have decreased significantly. It works well for me as someone with PCOS. It has a very comfortable scent, but it is very light. I don’t notice the smell after I rub it in. It really works and should consistently use.

soft finish for upper lip and chin area
I pay close attention to fine facial hair, especially around my upper lip and chin area. Under strong lighting, those small hairs can appear more visible, so I have been looking for a gentle way to care for this area without anything harsh or overly complicated. At night, after cleansing my face and completing my basic skincare, I apply this oil as the final step. It feels like a light finishing layer over the skin. I use a very small amount, about one or two drops, warm it between my fingertips, then gently press it onto the upper lip and chin area. There is no stinging sensation, and the scent is very mild, which makes the application feel calm and comfortable. The texture feels lighter than expected. It spreads smoothly and settles quickly without leaving a heavy or greasy film. My skin type leans slightly combination, and in my case it sits well without making the T zone feel overly coated. Even when I follow with a light moisturizer, it layers without pilling and still feels breathable on the skin. After using it regularly every three days in the evening, the change I notice is mainly visual. The fine facial hair looks less pronounced under bright lighting, especially around the upper lip area. The skin surface also appears more even, and when I touch it, it feels smoother and less uneven in texture. These changes feel gradual rather than sudden, becoming more noticeable over time. From a makeup perspective in the morning, my base applies more evenly after cleansing. Foundation tends to sit more smoothly around the chin and upper lip area, without clinging to texture. During humid days, the skin can feel slightly more active in oil balance, but the overall finish still looks even and natural once makeup is applied.

Good for maintaining clean beard lines
I keep my beard trimmed, but I always have to clean up the edges along my neckline to keep it looking neat. Lately, I've been massaging a few drops of this natural oil into my neck on Tuesday mornings right after I finish shaving at the sink. It feels really soothing on freshly shaved skin, kind of acting like a light daily moisturizer. The bottle is only 1.85 ounces, but you only need a tiny dab to cover a small area so it should last a while. Over the last month, the stubble along my collar line definitely feels softer, and it takes an extra day or two before it starts looking messy again. If you trim your own facial hair and want to stretch out the time between touching up your neck or cheek lines, this is handy to keep by the mirror.

Gentle Oil for After Hair Removal Care
I started using this Cyperus oil after shaving because my skin often feels dry afterward. The texture is lightweight and spreads easily, so I only need a small amount on areas like legs and underarms. I usually apply it after showering, when my skin is clean and dry, then massage it in for a few minutes. The oil feels soothing and gives my skin a softer, more moisturized feeling without being too greasy. It absorbs better than I expected, especially when I use a thin layer. The scent is mild and does not bother me during daily use. For unwanted hair care, I know it is not something that shows a big change overnight, so I use it consistently after hair removal. It has been easy to add into my routine, and I like that it helps calm and moisturize my skin after shaving or waxing.
