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.

Survives 7 months so far.
Color: Christmas Consuela, Size: Large Dog
It is still intact after nearly 7 months of constant play. My blue heeler normally destroys toys in just a few weeks. Consuela has exceeded expectations of survival with an extremely chewy, destruction prone dog.

Short-lived but much enjoyed as a chew toy
Color: Consuela the Cactus - Large, Size: Large Dog
I bought two of these for my "granddogs" in the size for Large dogs. The German Shepherd-mix stole the one intended for the border collie-mix and had both toys halfway destroyed within a day--I'm pretty sure they didn't survive much longer after that. Much enjoyed! Maybe I should've bought the Extra Large size, because the Large barely fit in her mouth and she wanted to play tug-of-war, so there wasn't much for me to grab onto. Then the border collie wanted in on the action (she's older, so she needed help tugging!) but there wasn't enough material for her to grab onto without accidentally sinking her teeth into me instead.

Love all the Barkbox toys
Color: Christmas Consuela, Size: Large Dog
This is our third "Consuela"! Our dogs LOVE these toys, and they are the most durable we can find for our heavy chewers. They really like the ball inside as well. Highly, highly recommend these toys. I won't be buying other toys anymore, just barkbox.

My dog is a toy destroyer
Color: Consuela the Cactus - Large, Size: Large Dog, Color: Consuela the Cactus - Large, Size: Large Dog
I’ve had a hard time trying to find toys that my dog, Zara loves because she’s actually very picky. Ive gotten plenty of Kong toys that are well known to be indestructible but she wants nothing to do with them. Then I got her ropes and that seemed to be good for a while until she was getting sick in the middle of the night from eating all of the string. Stuffed toys aren’t good because she’ll rip them within seconds and eat all of the stuffing. I felt like I’ll never score the perfect toy for her. I found the three layered cactus toy and decided to give it a go. It’s clearly designed to be ripped and destroyed to get the ball in the middle which is actually really cute and fun to see all of the layers. The cactus arms have stuffing and of course that’s the first thing she went for and ate. I had to watch her and make sure I took the stuffing away before she ate it. And before I knew it, she ate half of the first layer fabric lol once she got through the first layer, all she’s been doing is walking around the house with the toy in her mouth. But now she’s tired and passed out on the couch from all of the fun. This toy won’t last long with a toy destroyer but it sure does give them something to do and it’s a cute toy. I do recommend!!
