Premium Performance Roller Rockers designed specially for Shaft Mount applications using our very own 2 piece Shaft manufactured in house.
YellaTerra Platinum Race Rockers - The ultimate performance rockers for Chrysler Slant 6's
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.
Our wide range of true ratios allows you to achieve high lift without relying solely on your camshaft ... A trend many engine builders and racers alike are adopting to relieve the inertia on lifters and push rods generated by aggressive and often violent ramp rates required to make big lift.
Equipped with smooth low friction rollers allowing for high revving capability perfect for any street, strip, circuit or hill climbing application. Precision CNC anodised cradle providing unsurpassed rocker stability eliminating premature valve train wear and radically reducing side loading.
Reliable at high RPM with huge needle roller bearings. Your engine will run cooler, smoother and quieter.
100% Australian manufactured and designed, the ultimate go-fast-bit for the legendary Chrysler Slant 6 170, 198 or 225!
