Industrias Dolz launches its new range of Alternator Pulleys available to the Aftermarket, consolidating its position as one of the European Aftermarket leaders.

With more than 270 references launched, Dolz provides its customers with OAD™ and OAP pulleys of the best quality, ensuring that its products are at the forefront of the market.

It is a component associated with the engine’s auxiliary system, a link between the alternator and the crankshaft pulley. Thanks to its freewheeling coupling, it dampens the vibrations coming from the engine, helping to maintain the performance of the system components for as long as possible.

The electrical needs of today’s vehicles require more powerful alternators and greater complexity of the auxiliary drive of internal combustion engines, so to avoid vibrations and slippage in the entire transmission, freewheeling pulleys that work in a similar manner are required of damper.

Dolz’s range includes the two existing technologies on the market, OAP pulleys (Overrunning Alternator Pulley) and OAD™ pulleys (Overrunning Alternator Decoupler). Unlike OAPs that rely on the one-way clutch, OAD™ are also designed with a steel torsion spring that prevents torque oscillations and absorbs vibrations.

Of all of them, the Spanish manufacturer is already accepting orders.
