Toyota 1ZR/2ZR High Performance Valve Springs

The recent design of many engines is focused on lower possible parasitic losses and efficiency, the design of the valve spring needs to match these criteria also.

Valve springs on 1ZR/2ZR engines are just up to 7200 rpm but above or with the higher lift it would be safer to go with harder springs.

Our springs were designed and manufactured here in the UK with tighter manufacturing tolerances than OEM springs (and aftermarket versions) they are also 30% stiffer which we think is a great compromise between reliability, massive friction, and parasitic losses.

Also they not to hard to drain your lifters.

After manufacturing, the springs are shot blasted and super-finished for internal stress relief.

Sold as a set of 16. 

Also available as a kit with  titanium retainers here 

Some newer Lotuses are equipped with beehive type springs. Please check what is in your engine!!! Beehive type is available here.
