Valve Spring Set Race High RPM Lift Up to 13mm 4 Cyl & TS
[VSS12-1]
$145.00

For full race, these chrome silicon alloy springs will increase performance and reliability.

CUSTOMER COMMENT:

I just installed your valve springs.  I'm actually very impressed by the quality.  I checked them with a Rimac spring tester and managedto pair them into 8 sets with less than 1 lbs. in difference between the sets.  Regards--PT (Denmark)

With the popularity of 12 and 13mm cams, we are offering this upgrade spring.  The special alloy REM finishing process results in a harder more durable surface that improves the fatigue factor and reduces friction (heat) between inner and outer springs.

Our VSS12-13 Upgrade High RPM Springs became a necessity when customers began uising 12-13mm cams at sustained high RPM.  From our engine research, we developed VSS12-1 springs that could take this beating, maintain good pressure and resis fatigue.  With this upgraded spring, our most aggressive engine builders reported improved top end performance and improved spring memory.

Shifting at 7500-8000 is the general practice, but often it is necessary to extend this to 8000 and beyond on many race tracks and in red mist confrontations.  Tested up to 9000 on our dyno.
