Single Wound BC Valve Spring Kit for 1/2/3UZ with Titanium Retainers
This is the perfect solution for those looking to add more seat pressure for higher revs and larger cams in the UZ engine (non-VVTi and VVTI versions included). This single wound spring will work perfect with the factory retainer and keepers. Coil bind is an immense 550 thousandths. What does this mean? You can run more cam than the unmodified head will take! This spring is good to over 10,000 RPM with proper supporting mods. Seat pressure on standard 1UZ is 72 lbs, and in VVTi engines is 67 lb. Price is per set of 32 springs, for 1 complete engine.
