    LSX Performance Parts proudly supply the very best in performance valve springs for your build. Our LSX Performance Parts spring kit features the very best & most trusted brand in valve train components - BTR .660" lift dual polished valve spring kit.

    The BTR .660" lift polished springs kit features the latest technology in valve springs which ensures maximum spring life with its superior design & material integration. The PAC polished dual valve springs have a max lift of a huge .660" lift.

    These valve springs are designed to ensure excellent durability and longevity. These springs will work well with factory-style lifters (Highly recommend upgrading to LS7 lifters).  

    PAC polishes the valve springs, which helps to increase the overall life of the springs.  This greatly reduces the chances of spring fatigue and failure.  PAC's polishing process is completed without losing any pressure in the valve springs to maintain all of the capabilities of the non-polished version.

    We recommend a set of aftermarket performance lifters to suit this package as the standard lifters are not recommended.
