LOTUS / RENAULT INLINE 4 CYLINDER "A-Type" 1.5L & 1.6L Engines

PRODUCT DESCRIPTION:

Platinum

Designed for strength, built to race. No other rocker system compares with Yella Terra Platinum race series. Manufactured and assembled in Australia using the highest quality materials and componentry sourced locally and from the USA. Stability and durability well beyond the chequered flag.

Complete with fully adjustable aircraft grade extruded aluminium arms.
 
Equipped with smooth low friction rollers allowing for high revving capability perfect for any street, strip, circuit or hill climbing application. CNC anodized cradle providing unsurpassed rocker stability eliminating premature valvetrain wear and radically reducing side loading. 
 
Higher ratio rockers produce more lift out of a given cam profile. In addition, lift the valve off the seat at a much more rapid rate when compared with stock ratio rockers, producing increased airflow. Reliable at high RPM with huge needle roller bearings. Your engine will run cooler, smoother and quieter.

 

Key Features:

  • The YT 6783 Rockers are an easy fit Bolt on. 
  • Specifically Designed and Manufactured Rocker body for added strength in Hi-RPM Applications 1.7 Ratio
  • Tool steel Pin & Roller
  • Torrington BEARINGS
  • Chrome Moly Cup lash adjustment screws with Blackened 12 Point Nuts
  • 7/16” adjuster screw and heat-treated alloy steel jam nut to positively secure lash settings.
  • Each adjuster is broached for a big 3/16" socket to eliminate twisted hex keys.
  • Large diameter shafts are made from 4130 steel, deep case hardened and tempered for maximum wear resistance and strength.
  • Aircraft grade Aluminum rocker bodies made to our specifications for improved tensile and yield strength, and increased notch sensitivity, fatigue resistance, strength at elevated temperatures and chemical resistance.

 

Kit contains:

- 8 specifically designed & manufactured arms fully assembled with 24mm X Hole HD Lash adjusters & 12 Point Nuts, Torrington Bearings and specifically ground Roller Tips

- 1 Specifically machined and ground shaft ensures maximum stability at HI-RPM 

- Blackend Spacers & Washers to complete the assembly

-Assembled and ready for pre-lubrication and installation.
