Power Driven 8v Valve Springs for 4BT

These Power Driven Diesel 8v 60 lb Valve Springs are capable of handling engine speeds of up to 4,500 rpm, providing improved performance. However, it's important to note that while the springs themselves are durable, the stock keepers and locks may not be suitable for racing or pulling applications. For individuals planning to engage in competitive events, you should strongly consider the beehive springs with upgraded locks and retainers to ensure optimal performance and reliability. These upgrades will provide the necessary strength and stability required for demanding racing or pulling conditions.
