 Product Description

buying-2-discount-300pxl-.png● YUMINASHI HIGH LIFT PROGRESSIVE DOUBLE VALVE SPRING & RETAINER SET (NAVI110 / ACTIVA110 G3)

● Dedicated YUMINASHI double valve spring & retainer set for the NAVI110/ACTIVA110 cylinder heads to run high RPM's with stock and higher degrees / lift camshafts.

● Nothing more annoying then to figure out after removing the RPM limit on your NAVI, that your valve springs can't handle it!...

● The YUMINASHI valve springs for the NAVI110/ACTIVA110 are progressive valve springs, which means the deeper they go, the stronger they become.

● These valve springs are also high lift valve springs, and this means that the distance between each of the coils are specifically calculated and worked out to avoid coil bind with high lift camshafts.

● These springs can handle a maximum lift of 13.61mm (0.53582inches) measured from a rest position.
About 1.52mm (0.060 inch) used to be the textbook safety margin, with more OK, which can be less now with modern spring technology, and with this in mind we can state that these progressive valve springs are perfectly safe and recommended to be used in combination with the YUMINASHI 240° and 250° camshafts with a 7.52mm Intake lift and a 7.47mm exhaust lift... 

● The special retainers in the set are again designed to handle a much larger lift compared to stock, this creates again an extra margin between the retainer and the valve guide on the stock cylinder head.


● THIS HIGH LIFT PROGRESSIVE DOUBLE VALVE SPRING & RATAINER SET COMES COMPLETE WITH:

  • 2 X Outer Springs
  • 2 x Inner Springs
  • 2 x Special High Lift Retainers
  • 4 x Special Valve Cotters (※ Stock NAVI/ACTIVA valve cotters can't be used)
