Denstoj have cleverly developed these lifters to include a retaining clip to prevent the rocker arm from detaching from an unpredicted valve event (misfire, over-rev, limit, etc).
The rocker retainer clip simply clicks onto the OEM rocker arm. These solid lifters have been machined to accept the retaining clip.
This kit can be used with Kelford’s 186- series of camshafts for solid lifter conversions on OEM hydraulic lifter cylinder heads.
Professional installation is required to achieve the correct lash setting.
*note: these lifters are not suited to the OEM solid lifter GTI-R Pulsar cylinder head, they suit a hydraulic to solid conversion on Silvia/Primera/Pulsar/Bluebird.
