Abstract: A roller lifter for an internal combustion engine (10) includes a cylindrical lifter body (100) having a first end (104), a second end (106) and a roller (110) rotatably attached to the first end (104). The first end (104) has a first diameter (Di) and the second end (106) has a second diameter (D2) greater than the first diameter (Di) and a flat surface configured to engage a corresponding flat surface on an adjacent roller lifter and to prevent axial rotation of the roller lifter while in use. The roller lifter may further include a recess (108) extending along a longitudinal axis (102) from the second end (106) toward the first end (104).
