Trickflow Gen X 215cc, 225cc, 235cc

Designed for Trick Flow LS1 Cylinder Heads

Yella Terra’s Trick Flow LS1 inlet rockers feature a dedicated pushrod-end offset to provide a straighter pushrod path towards the lifter while maintaining correct roller alignment on the valve tip. Compared with competing LS shaft systems that retain standard LS1 inlet-arm geometry, our application-specific design helps reduce sideways pushrod angle and improve clearance through the cylinder head.

Yella Terra is also the only manufacturer offering this application in both 8 mm and 10 mm mounting versions, giving engine builders a choice to suit their cylinder-head mounting requirements.

  • Dedicated inlet-arm offset to suit Trick Flow LS1 heads.

  • Improved pushrod alignment without compromising valve-tip alignment.

Choice of 8 mm or 10 mm mounting versions to match your cylinder heads.
