2GR-FE/2AR-FE High RPM valve spring, retainer and lash cap combo

I have worked with Supertech to come up with a valve springs, retainer and lash cap combination that work at higher RPM than the stock springs. These are the right spring pressure to handle up to 8300RPM in the 2GR-FE and 8400RPM in the 2AR-FE. Note these RPM values are with the stock cams it should also be similar with most aftermarket camshafts but please reach out via the contact-us link to confirm capability with your particular camshaft profile.

Specs:

Seat Pressure: 84Lbs

Pressure at 12mm lift: 164lbs

Max valve lift without reduced lifespan: 11.8mm

Max safe lift with reduced lifespan: 12.5mm

These springs will coil bind at 14.8mm of lift but the supplied retainer will hit the valve seal at 12.8mm of valve lift.

Valve springs are rarely the only upgrade on a motor, if you have any questions about suitability of these for your application please reach out and contact me.

The installation tool that is optionally available is a Toyotool VMT2AZ, you can keep it if you would like or return it in usable condition within 3 months of original purchase for a $75 refund.
