Product Description
These new JWT Beehive springs are designed to handle even the largest JWT VQ profiles (.600”+ lift) with about 3g less combined spring & retainer weight than the original VQ parts! Reliability is greatly improved by use of super clean wire material, followed by enhanced additional heat treating with a nano-peened and polished finish. The varied coil diameters of this beehive spring dampen harmonic resonance that can cause a conventional spring to surge at critical RPMs causing the valve to bounce on the seat or float.
***This spring uses the lighter 2013+ VQ retainer (ID 12.3mm), and these retainers NEED to also be purchased if used in an earlier VQ engine with the earlier (ID 17.6mm) retainer.
NOTE: These springs and retainers do not include new Spring Seats/Shims, but they were designed to be used with the OEM VQ Valve Spring Seat (Shim).
If you are using an aftermarket cam set with these springs, please make a note with the specifics of the cams (Brand, Series, Lift, Duration) in the comments section during checkout. If no comments are made we will send springs / shims configured for use with stock cams.
