Porsche 944/924S lightweight alternator pulley: worth it?
Lightweight vs underdrive, what an aluminium alternator pulley really changes on a 924S/944, which models it fits, and how to swap it in under an hour.
A small workshop designing engine, suspension and interior parts for the 924S and 944.
Designed in-house. Produced in France.
What we make
Paddock Service isn't a catalogue. We pick one weak point at a time (a plastic water pipe that cracks, an alternator pulley heavier than it needs to be, a throttle cam with lazy first travel) and design the part we'd want to fit on our own car. Drawn in CAD, prototyped, tested on a 924S, then produced in small runs.
Some parts replace OEM items that are no longer available. Others improve a factory design. All parts are made in Europe.
How it started
Paddock Service began as a restoration project.
When the right parts turned out to be either no longer available or a transatlantic order away, I started designing them, first for my car, then in small runs for other 924S and 944 owners.
Guides
Maintenance, upgrades and buying notes from the workshop.

Cast cracks, rusty flanges, and mismatched silencers: how to choose an exhaust manifold that fits Porsche 924S and 944 — and what stainless changes.
