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.

Good quality car care kit
Style: KIT
This product was specifically asked for by my adult son. Upon opening, it had leaked (it was a gift so I did not open) but he went ahead and used it. Good quality, car care product.

Not so good….
Style: KIT
On a brand new car used the citrus car wash product with the 2 bucket method and the interior and glass cleaner. The citrus product sank to the bottom of the 5 gallon bucket, despite all efforts couldn’t get it thoroughly mixed in the water. Used it anyway with the microfiber mitt - this mitt was excellent and I was satisfied with the wash (car was clean before washing except for bird droppings) except for eye irritation from a teeny splash. On to drying - the included microfiber drying towels were worse than worthless. They stuck to the surface of the car and shedded fibers all over the paint. I had to hose off the car to get rid of the purple lint it deposited wherever it touched the car. Larger chunks of lint came off the cloth as well. I used the interior and glass cleaner only on the interior of the windshield. Got in the car this AM, there was a haze on the entire windshield inner surface. Chemical Guys has excellent marketing and video tutorials but I’d recommend purchasing better quality components rather than what’s in this box. The ingredients in the wash, interior cleaner, and wheel cleaner are also not good for the environment, eyes, or skin. I wonder what the runoff from this one washing will do to our and neighbors’ vegetation.
