JE Pistons LS Series 15-Degree Dome Pistons

One of the best forged pistons for your high performance LS engine, JE Pistons 15-degree domed pistons.

The exclusive asymmetrical skirt maintains a larger skirt area on the heavily stressed major thrust side, while reducing friction with a smaller skirt on the minor thrust side. The result is high-strength, lightweight pistons that outperform the competition. Select the LS Series pistons needed for your performance setup.

* Accumulator grooves
* Double pin oilers

* Includes round wire locks
