Show original supplier description
The Brian Tooley Racing Platinum .660" Dual Spring Kit offers a proven and widely adopted valvetrain upgrade for GM LS engines that are utilizing aftermarket camshafts. This kit features polished dual valve springs, which provide increased seat and open pressure to significantly reduce valve float when compared to stock single-spring configurations. These are paired with high-strength steel retainers, ensuring excellent longevity and service life for demanding performance applications. The complete drop-in nature of this kit means it includes everything necessary: polished dual springs, steel retainers, locators for stock guides, locks, and seals, eliminating the need for additional purchases. Key specifications for this valve spring kit include a .660" lift capability, a 1.300" spring diameter, 155 lbs of seat pressure at 1.780", and 380 lbs of open pressure at 1.180". The coil bind height is 1.070". This kit is compatible with most factory LS cylinder heads and specifically fits 4.8L, 5.3L, 5.7L, 6.0L, and 6.2L LS engines, including popular variants like LS1, LS2, LS3, LS4, LS6, L76, L92, L99, LM7, LQ4, LQ9, L33, and LSA. It is important to note that while this kit fits most factory LS cylinder heads, LS7 cylinder heads will require the use of a .030" shim, and this kit will not work on LS9 heads.
