Mace 1.9 ratio roller rockers (up from 1.65) are suitable for Holden Commodore and similar platforms fitted with Ecotec (L36) or L67 supercharged V6 engines. This is a very cost effective way to bump up the performance of your vehicle, by increasing valve lift and allowing your engine to breathe much more efficiently.

Manufactured by a renowned engineering company you can be assured of the outstanding quality and workmanship of these remanufactured rockers.


Key Benefits:

  • Gains of around 13 to 16kW are not uncommon. Higher in some cases where others mods have been undertaken.
  • In addition to top end gains, excellent low to mid range power gains are also achieved with these rockers.
  • Its an easy DIY mod and takes around two hours to be done unlike a complete cam change. A cam change can take a good part of a day and is more complex to undertake meaning higher installation costs along with the cost of a retune which these rockers don't require, potentially saving you thousands!
  • Unlike some aftermarket rockers these don't 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) to prevent this valve float from occurring, power output drops because the engine 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!

Vehicle Fitment Guide


Notes:

  • Rockers with ratio higher than 1.9 are not suitable for use with an aftermarket camshaft unless the cam was designed for them because the excessive amounts of lift will potentially cause engine damage.
  • These rockers alone are not recommended to be used in VY series Ecotec and L67 Supercharged V6 engines due to extra casting flash around the pushrod cavity. These engines must use a thin walled pushrod to gain the required clearance. A kit comprised of rockers and pushrods can be purchased through another listing.

Worth it!
Size: Queen(Pack of 2)
These pillows are amazing and very soft and comfortable. They came nicely packaged and I let them sit out for just a few hours before using them and that was plenty of time! They come with the cooling cover and fit a standard queen sized pillowcase. The material expands well and does not have any weird smells. 10/10 well worth the price.

Miracle pillow
Size: Standard(Pack of 2)
Best pillow I’ve ever had. I have been using this since December 2024 and it still hasn’t gotten flat. It is amazingly comfortable and solves all my neck issues for a side sleeper. My head never gets hot either. I’ve recommended this to my friends and they’ve had success with it as well.

Really wanted to love these
Size: Queen(Pack of 2)
I really wanted to love these but they gave me a stiff neck. I haven't slept with a pillow since buying these. They are firm except where you lay your head. It just deflates there. I expected it to sink in to match the curve of my neck but it was more than I could handle. My head ended up in a valley between the two ends of the pillow. The price was good, zipper worked fine, it looks as advertised and the pillows are good quality. The cooling part works, its just not what I needed.

best pillow I have ever bought.
Size: Queen(Pack of 2)
most comfortable pillow I have ever bought. It seems very well put together so I believe that it will last a long time. Very happy with the purchase. I do think the weight of the pillow will surprise many people because while it is quite heavy, it is very firm and extremely comfortable. Great value.

I paid for the product and it’s GOOD 👍🏽
Size: Queen(Pack of 2), Size: Queen(Pack of 2)
Honest review to help your decision. These are a bargain at two for one. I paid almost $30 for one at a local retailer and it’s already flattened after 7 months. This product arrives vacuum sealed with the cooling pillow covers separately (separate so you can wash before using). They are loaded with memory foam which I found pleasing. I chose to leave all of the foam in because I’m sure it’ll flatten sometime in the future. I’ve been using these for TWO MONTHS now and they have not flattened. Easy to mold and fluff, soft and they are added support for my back up pillows. I cannot attest to any type of pain relief because I have not experienced that with these personally. I do feel my sleep is better so my tension headaches have lessened. The cooling hex layer is on the cover NOT the actual pillows. I’m sure everyone knows that memory foam gets really hot 🥵 but the cooling covers on these help minimize that. It actually feels cool to the touch like a gel product. I find the quality to be exceptional. All in all, give it a shot.
