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.

Excellent tool, convenient and adjustable
Size: 2.0
This is a great design and a quality product. The angle adjustment for the needles is super helpful, allowing the exact distance needed for any size portafilter. Needles are removable if a less dense pattern is desired, and they are easily replaceable as well (spare needles are also provided)! The magnetic stand works well, and the magnets have the perfect amount of force to hold it in place but allow easy removal. I was a tiny bit disappointed that the base did not come with any type of rubber or silicone non-skid, and do recommend adding some to the bottom so it doesn't slide around on your countertop. I highly recommend this item!

Great tool, but be careful when you replace a needle.
Size: 2.0, Size: 2.0
Great idea, you can arrange the needles in either direction, depending upon the direction that you move the tool (clockwise, or anti-clockwise). But be VERY CAREFUL in dismantling, as it may come apart on you, spilling needles. Getting the needles lined up takes time and patience. Replacing one by itself should be easier. 3BOMBER would do well to include an exploded view of this tool in the instructions so owners know what to expect. That said, this works great, and the magnetic attachment to the stand is very convenient — easier than a stand with a hole in it. Also, the flat top lets you set it upside down in a jiffy. Definitely recommended.

Makes all the difference in your extraction.
Size: 2.0, Size: 2.0
This little guy improved the extraction quality without being overly complex. After grinding there were always high spots in the porta filter when I put the grinds in. There are several different ways to distribute the grinds and I found this to be simple and effective without breaking the bank. The weight is nice and comes with extra pins just incase you bend yours. I've had mine for over a year and haven't needed it so it's nice that it's available. Simple practical tools like this are great in the setup and show you don't need to break the budget to have a solid coffee setup. I enjoy the 3BOMBER line of tools. For the money they offer the best value
