Exclusive to Mace are our 1.98:1 ultra-high ratio roller rockers (up from 1.65:1) to suit VS-VX Commodores and similar platforms fitted with the Ecotec 3.8L and the L67 Supercharged 3.8L V6 engines. These are the highest commercially available rockers on the market for the Ecotec and L67 engines. It's a very cost-effective way to increase the performance of a Commodore, by increasing valve lift, allowing your engine to breathe much more efficiently.
Manufactured right here at Mace Engineering, so you can be assured of the outstanding quality and workmanship of these remanufactured rockers.
Key Benefits:
- Gains of around 16 to 26kW are not uncommon. Higher in some cases where others mods have been undertaken.
- The job takes around less than two hours to complete so its an easy DIY mod, unlike a complete cam change, which can take a good part of a day and is much more complex to undertake. Meaning higher installation costs, plus the cost of a retune which these rockers dont require - potentially saving you thousands!
- Unlike some aftermarket rockers, these dont require spring upgrades (as they best preserve the factory valve train harmonics) to prevent them from having valve float, hurting power and causing engine damage.
- Even when valve springs are upgraded (which is a costly exercise in itself) to prevent this valve float from occurring, power output drops because the engine now has to work against these stiffer springs. Basically, it can be a case of spending more money for less power than what these rockers have to offer!
- In addition to top end gains, excellent low to mid-range power gains are also achieved with these rockers.
Contents:

Vehicle Fitment Guide
Notes:
- All rockers which have a ratio equal to or greater than 1.9:1 are not suitable for use with aftermarket camshafts unless they specifically were designed for them.
- Ultra high ratio rockers are NOT compatible with any VY V6 (Ecotec 3.8L or L67 Supercharged 3.8L) due to the excessive casting flash found in the pushrod bores. The only way these can be made to work is by removing the heads and have the flash cleaned up by a professional.

Sharp but safe
Color: 6pcs, Color: 6pcs
Sharp, safe and effective razors. 2 different sizes but I have only used the smaller ones so far on eyebrows and upper lip. The handles are plastic but easy to grip and have a firm grasp. Close cut and it left my skin feeling soft. Great that there are 6 in the pack, these should last a while.

Works great
Color: 6pcs, Color: 6pcs
I'm 42,as I have been getting older,I have gotten a lot more peach fuzz in the face. I just started dermaplaning about 5 years ago,off and on. I have tried so many of the little electronic ones, only for the batteries to die fast or not work at all, they would stop working right away or break very easily. Some of them didn't work how I wanted them to work and I'd have to keep going back over and over my face just to get a good shave. I love these ones,they're cheap to start with,and it comes with 6 ,there's 4 bigger ones and 2 that are a tiny bit smaller,so you can use the smaller ones for smaller spaces,say above the lip,whereas the longer ones are better for longer swipes like on the cheeks. Another thing I love that other ones don't always have (the electric ones always have lid covers but the manual ones iver gotten haven't) ,these ones all have lids that fit nice and snug on top,that way you don't accident cut your fingers or hands when taking them out. It also comes with a nice little plastic carrying case which I live also because my other single ones always end up at the bottom of my drawers and I have to dig for them,with the case,they're all together and no need to search for them as you can't miss the case. Now how they work, it is easy to use,glides right across the facial areas with no problems. They're sharp(I believe it said Japanese stainless steel?) Makes it easy to glide across the face and not need to go over again so many times like you do with some others,if there's still a bit of fuzz left, go over it again, but I promise you'll go over your face a lot less times than some others. Make sure you have put on so.e type of moisturizer before using these,never dermaplane on dry skin. I'm glad I got these,will keep buying from now on!

Smooth Flawless Skin
Color: 6pcs, Color: 6pcs
I absolutely love these dermaplaning razors! The stainless steel blades feel sturdy and high-quality, giving me confidence every time I use them. They work amazingly well, effortlessly removing peach fuzz and dead skin without causing irritation. After using the razors, my face feels incredibly smooth and refreshed, like a mini facial at home. I appreciate how easy they are to handle and how precise the blades are, making dermaplaning simple and effective. These razors have become an essential part of my skincare routine, and I highly recommend them to anyone looking for a reliable and gentle dermaplaning tool.
