Brian Crower Toyota 2JZGTE/Lexus 2JZGE/1JZGTE Dual Spring/Titanium Retainer Kit/Seat Kit

BC heavy duty springs are designed for up to 9000 rpm and 800whp, while the single springs are rated for above 800whp and an increase in spring pressure for extended rpm's. BC valve springs by PAC Racing are wound from only the highest grade, super clean, chrome silicone alloy and feature proprietary processing procedures for consistent pressures. Brian Crower titanium retainers represent the pinnacle of lightweight performance, weighing approximately 40% less than standard OEM steel units. These retainers are CNC machined from premium 6AL4V titanium bar stock to precise tolerances. Brian Crower valve spring and titanium retainer kits are precisely matched systems designed to work together seamlessly, ensuring improved valve control at higher RPMs. This compatibility allows for higher lift camshafts, enhancing both performance and reliability.
