Product Details

The Wiseco PTS535AS Pro Tru Street forged piston set is engineered for the Small Block Chevy (SBC) 400 platform, delivering a high-compression +8cc domed crown design built for serious street and strip performance. This complete kit includes eight forged pistons along with a matched ringset, wrist pins, and Spirolox retainers — everything needed for a proper high-performance engine build.

Constructed from forged 4032 alloy, these pistons offer excellent strength and heat resistance well beyond what cast or hypereutectic pistons can provide. The hollow dome design adds the positive displacement needed to achieve aggressive compression ratios suited for naturally aspirated high-performance and race applications.

This kit includes chromium alloy steel wrist pins and Spirolox retainers for a complete, ready-to-install assembly. Designed specifically for the 23-degree Small Block Chevy cylinder head configuration, the PTS535AS is an ideal choice for builders targeting maximum compression with a 400 SBC short block.
