2GR-FE/2AR-FE valve spring 8000rpm
These valve springs are a light upgrade for the 2GR-FE and the 2AR-FE to safely bump the max RPM up. With the stock camshafts these will allow the 2AR and 2GR valvetrain to safely hit 8000rpm. Note the stock 2GR-FE bottom end max safe RPM is 7800RPM, beyond that seems to be problematic in some motors.
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.
Note that these valve springs reuse the stock valve spring retainers but they are only compatible with the straight stock spring, a few 2GR-FE motors got beehive springs from the factory, those would need the retainer replaced with the larger style.
