JWT DE / HR / VHR Valve Springs & Retainers

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.

* DE / HR motors will require a quantity of 24 valve springs and retainers (intake and exhaust sides), while the VHR motors will only require a quantity of 12 (exhaust side only)
