BTR is proud to introduce our new SK021 conical style valve spring kit. This is a great option for camshafts using less than .625" valve lift. This budget friendly valve spring kit was designed to use our conical locator, and BTR offset locks, but use the OEM LS7 retainer. Features include tumble polishing for reduced stress risers and a quality appearance.
The BTR SK021 valve spring kit works for LS7 applications, and whether you're looking for longevity in street applications, or for use in single valve spring only limited racing classes, BTR has you covered. As with all BTR valve springs, they have been extensively tested on our in house Spintron machine and engine dyno.
