Mace 1.9 ratio roller rockers (up from 1.65) with Crow Cams pushrods 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.


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.
  • The use of a thin walled pushrod is compulsory for all VY series Ecotec and L67 Supercharged V6 engines due to extra casting flash around the pushrod cavity. Earlier models are not prone to this issue and can re-use the standard pushrods with our high ratio rockers. These rockers only can be purchased through another listing.

Nice shoes!
Size: 11, Color: Black Full Grain
I bought them in black and I like them so much I will be buying the brown soon. They fit true to size and are comfortable and stylish. I like the clean simplicity. They're basically a dressy sneaker which is perfect for my job's 'dress code'. Yet they're stylish enough to be worn weekends or a night out. They seemed just a touch stiff out of the box but IMO that's completely normal and fine - after just a couple days of wearing them they are breaking in nicely. No complaints on that. They seem to be of very high quality and I'm very happy with them.
