***OUT OF STOCK***
MACE 1.98 ULTRA HIGH RATIO ROLLER ROCKER KIT TO SUIT HOLDEN ECOTEC L36 L67 SUPERCHARGED 3.8L V6
Vehicle Fitment: Calais VS VT VX, Caprice VS WH, Commodore VS VT VU VX, Monaro V2, Statesman VS WH
For further details, please refer to the vehicle fitment guide in the above image.
Part Number: ROC602
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 it’s 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 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 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.
Contents:
- 1 X Set of Ultra-high ratio rockers
- 1 X Set of pushrods
- 1 X Set of rocker bolts
- 1 X Tube of assembly lubricant
- 1 X Bolt pack
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.
