Crane hydraulic roller lifters are offered in two basic designs: Those for use with standard factory alignment bars (on engines originally equipped with hydraulic roller lifters); and vertical locking bar drop-in lifters (designed to retrofit engines not factory-equipped with hydraulic roller lifters).

Crane Replacement Series hydraulic roller lifters are designed for use with standard factory alignment bars and are available in normal dimension versions for use with standard lobe lift and standard base circle diameter cams. When lobe lifts increase, and base circle diameters decrease, Crane's exclusive long-travel design lifters must be used to prevent the lifters from dropping out of the factory alignment bars when on the base circle of the camshaft. This would allow the lifters to rotate, causing severe engine damage. As these lifters are for engines originally equipped with hydraulic roller lifters, special length pushrods are not usually required.

Crane Retrofit Series hydraulic roller lifters with vertical locking bars are available for non-hydraulic roller-equipped engines. They can also be used in many applications to replace factory hydraulic roller lifters and alignment mechanisms. No machining is normally required for the drop-in installation of these lifters, however with differences in block castings and camshaft base circle diameters; care must be taken to insure that neither the locking bars, nor their attaching rivets, contact the block casting throughout their normal cycles. If there is any interference, the block can be ground to provide the necessary clearance. This should be checked prior to final engine assembly. When used in retrofit applications, special length pushrods are required. The retrofit vertical locking bar lifters are machined from 8620 steel billet, heat treated, and assembled at Crane's own facilities. Precision-fit plunger assemblies are used to provide proper bleed-down rates, permitting high-rpm use in properly set-up engines. The additional inherent strength of the 8620 material also maintains greater stability in the lifter body, permitting more consistent operation in very high spring pressure and high-rpm applications, by keeping the plunger to body clearance consistent throughout the operating range. Retrofit lifters also utilize Crane's latest Monel pin and retaining flange assembly to attach the guidebar, providing superior long term durability.
