ECS Lightweight Underdrive Crank Pulley for VW 2.5L -

Lightweight aluminum crankshaft pulleys from ECS Tuning punch above their weight. Precision machined from anodized billet aluminum, our great looking upgrades bolt on easily in place of your portly stock pulley.

Choose from stock diameter or underdrive. Either pulley reduces rotational mass for faster throttle response. The underdrive option reduces parasitic horsepower loss.

The bare stock pulley works with your standard length accessory belt; the underdrive kit comes with a shorter Bando belt.

Buy them for function. Because they look great. Or both!

Hmm... I'm considering one of these. Any tradeoffs/downsides or negative long term effects? Also looking up a DIY after I post this to see if its within my mechanical ability

Some of the damping properties are lost. Although we have tested these pulleys rigorously for many thousands of miles without any side effects.

When taking the old pulley off it is better to leave the belt on crack the bolts loose, then remove the belt and pulley/bolts after.

Holding the stock pulley in place can be done with a pry bar or screw driver within the spokes.

The stock pulley has a certain weight to help tone down vibrations, with our kits you will loose that dampening - yet again still no problems.

Still have seen no issues with battery/charging issues.
