Drivetrain: Precision Components for Power Transmission and Driving Dynamics
The Drivetrain category offers carefully selected components for the power transmission systems of classic and modern Italian vehicles – with a special focus on Alfa Romeo. As OKP, your specialist for Italian automobiles with over 20 years of experience, we provide a comprehensive selection of original parts and precisely manufactured reproductions for gearboxes, clutches, propshafts, rear axles, and differentials.
Our focus covers the entire Alfa Romeo model history – from the early 6C 2500, 1900, and Giulietta/Giulia series (750/101 and 105/115), to the Bertone Coupés, Spider, Alfetta, 75, and GTV/Spider 916, all the way to modern models like the 156, 159, Giulia (952), and Stelvio. We also offer selected drivetrain components for Fiat, Lancia, Maserati, Ferrari, Lamborghini, and performance parts from Nardi and Ansa.
In this category you’ll find essential elements of the powertrain:
-
Precision clutch kits, dual-mass flywheels, synchronized gearbox components, and bearing sets – for both standard and rare Alfa transmission types.
-
Propshaft bearings, flex discs, and universal joints, available as originals or accurate reproductions – ensuring smooth, vibration-free operation.
A particular focus lies on rear axle and differential technology: from crown and pinion gear sets in various ratios to limited-slip differentials, complete bearing units, and seal kits for Transaxle models such as Alfetta, GTV6, or 75.
All components either match the original specifications or have been optimized for increased durability in wear-prone areas – without compromising the authentic character of the drivetrain.
At OKP, we stand not only for premium parts but also for deep technical expertise in restoring, maintaining, or upgrading the drivetrain of your Italian classic or everyday Alfa. From the clutch disc to the differential shaft – we deliver precision that puts the power exactly where it belongs: on the road.
