Toyota 1ZR/2ZR High Performance Valve Springs

£179.50
SKU L42

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.

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 

Why our parts?

Our parts are engineered and developed with the highest possible performance and reliability in mind.

Designed and manufactured in the UK for very strict tolerances and consistency.

Cars are our passion and all we provide is the highest possible quality.
