Product Details

This complete set includes our Achilles Motorsports Dual-Spring Valve Springs, spring seats, your choice of Steel Alloy or Titanium retainers all designed to work together harmoniously!

Achilles Motorsports Valve Spring Kits are engineered and developed to be used specifically for BMW high performance and race engines. The have been extensively tested and shown to perform flawlessly with Schrick and BMW Motorsports Cams. Our springs are the correct installed height and seat pressure recommended specifically by BMW Motorsports and Schrick Cams for cams up to 12.5mm of lift.(For High Lift Cams See our Achilles Motorsports Valve Spring Kit BMW S54 - 14mm High Lift Cams) Our specific quality of materials and production process leaves nothing left to be desired from a true motorsport type valve spring kit!

The tolerances of our Achilles Motorsports Valve Spring Kits are tightly engineered for motorsports, we worked hand in hand with Eibach Springs from Germany one of the world's most prestigious and experienced manufactures to produce a set that could pass all of our requirements and expectations. So, when you purchase one of our kits for your BMW rest assured it will be the optimum specification for your application.

Our valve spring kits for the BMW S54 engine are of dual-spring type with frictional damping meaning the inner and outer springs rub together slightly. This helps prevent excessive spring resonance by using the friction on one another to damp out any motion or excessive resonance before it can cause unnecessary fatigue or damage to the springs. Also, in the sudden event that one spring breaks the other will keep the valve from dropping and making contact with the piston.

Titanium retainers should only be selected for race engines. The extreme light weight of the titanium ensure the absolute maximum weight savings and performance but due to the nature of the material, they need to be inspected regularly.

Steel Alloy retainers are an incredible upgrade over the stock retainers. They are recommended for street driven vehicles & those looking for maximum endurance or extended service intervals. Perfect for street or race engines! For longevity or endurance type racing we recommend using our steel alloy retainers which can manage the stress for a much longer durations of use.
