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. They feature JE's FSR (forged side relief) engineered for today's high-power normally aspirated and forced induction LS engines. 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
* Offset wrist pin
* Includes round wire locks
* Designed for 1.2/1.5/3mm and 1.5/1.5/3mm rings
