BTR Beehive Exhaust Valve Spring Kit 05-up Mopar 6.1, 6.4 Hemi

BTR introduces their new Beehive style valve spring kits that provides a great option for camshafts using less than .625 in. valve lift. These budget friendly valve spring kits were designed to use BTR's Beehive locator, and factory retainers and locks. Features include tumble polishing for reduced stress risers and a quality appearance. These BTR valve spring kits work for a wide range of applications, 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 their in-house Spintron machine and engine dyno.

These are sold as a set. These are the perfect springs to upgrade your 03-10 5.7L Hemi! They are much stronger than the OEM springs on the 5.7L.
