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.

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.

Still soft but looks terrible after 1 wash. Save your money
Color: White, Size: Small, Color: White, Size: Small
Update: sweater looked great when I received. After 1 wash it looks terrible. Looks like it’s been washed too many times, material fuzzy and piled. After wearing it once, it snagged and the knit pulled through. I would NOT recommend. I had such high hopes. Save your money. Very nice sweater, especially for the price! I love the details of the buttons on the sleeves. It is SO soft. It’s not super thick as I can see my skin through it when pressing my hand up against fabric. However, it’s not see through when wearing it. It’ll be perfect in cooler weather and perfect in the winter with a coat but won’t cause me to overheat when in a heated environment. I do feel like it runs big. I could have sized down a size. Although I’m not sure if it’ll shrink after a wash or two.

Disappointed.
Color: Blue, Size: Large, Color: Blue, Size: Large
This sweater is so comfortable and very soft. It fits well in a flattering, oversized way. But after one wash it is pilled everywhere which makes it look old and shabby. It’s at a price point where I feel compelled to return it.

cute but not the material I expected
Size: Small, Color: Pure Black
This was really cute, well made and fit as expected. Unfortunately, I have sensitive skin and I found the material to be scratchy so I sent it back.
