Enginetech P50125STD Cast Piston Set GM 3.5L 211 DOHC Standard Bore

The Enginetech P50125STD is a cast aluminum piston set engineered for the GM 3.5L (211 cu. in.) DOHC inline-five engine. Designed as a direct OE replacement, this standard-bore (STD) piston set is built to restore proper compression, seal integrity, and engine performance during an overhaul or rebuild.

The GM 3.5L Atlas DOHC engine features a 93 mm (3.66 in.) bore and 102 mm (4.02 in.) stroke. The Enginetech piston set is precision-manufactured to these OE specifications, making it a reliable drop-in replacement for worn or damaged pistons on engines at standard bore size.

Key Features:

• Cast aluminum construction — matches OE material requirements for this application
• Superior size and weight grading — each set is carefully matched within tight tolerances for balanced performance
• Decked to compensate for bore and deck variations — most sets are decked 0.010–0.020 in. to account for oversized bores and head or deck milling
• OE-quality treatments as required — may include skirt coatings, anodized crown, or Ni-resist inserts depending on application demands
• Standard (STD) bore size — designed for engines at factory bore specification
• Meets or exceeds OE specifications — engineered for domestic engine rebuilding applications

Enginetech is a trusted name in engine rebuilding components, supplying professional engine builders with pistons engineered for domestic applications. The P50125STD piston set is the correct choice for a standard-bore rebuild of the GM 3.5L 211 DOHC engine.
