Key features

OEM MAHLE / Letrika Manufacturing QualityFabricated to tight original equipment tolerances, preventing radial runout, shaft vibration, and harmonic imbalance at high engine speeds.
Aerodynamically Optimized for Clockwise Rotation (↻)Vane pitch and curvature draw forced air through the alternator housing to effectively cool internal diode bridges and rotor slip rings.
High-Strength Heavy-Gauge SteelFormed from corrosion-treated sheet steel designed to resist fatigue deformation, airborne grit abrasion, and field debris impact.
Calibrated Fitment Dimensions (17 x 127 x 14 mm)17 mm central bore matches standard Iskra / Letrika / MAHLE rotor shafts, while the 127 mm outer profile nests cleanly behind standard drive pulleys.
