Description Technical Specs Extended Information
Australia's No:1 Performing High Ratio Rocker for the Past 5 Years !!
With the combined force of V6 Performance and FIT Development we are Proud to announce the addition of FIT's Immensely Popular 1.9:1 High Ratio Rockers to our Product Range.
This style of 1.9:1 Rocker has consistently been voted the Best Performance Rocker in Australia
The FIT 1.9:1 High Ratio Roller Rocker Arms Increase Bottom-End Torque, Mid-Range Punch and Top-End Power with Absolutely No Loss in Sophistication, Fuel Economy or Driveability.
By increasing the Holden Factory standard rocker ratio from 1.65:1 to 1.9:1 on both Ecotec and Supercharged V6's we have managed to Improve the Entire Power Band and Torque Delivery. The Results are Similar to a cam swap but with no where near the work or cost involved.
We often see gains of 10-20kW, with the majority recording 13-16kW from simply swapping the stock rockers to our 1.9:1 High Ratio Roller Rockers. Well known FIT 1.9:1 High Ratio Roller Rockers are easily installed DIY or with General Mechanic with no special tools required.
Dyno Graph of XU-6 with fitted with 1.9 Rockers and Boost Upgrade:
An Improvement of 18rwhp from the Rocker's Alone !!
This is a Great Example of how Close to 20rwhp can be added by a Simple Bolt-on Product. We normally advertise between 10-20kW for this product, and this proves we are right on track.
*NB: When purchasing for VY Series we Strongly Recommend 5/16"s Pushrods.
