Manley Chevy LT1 Direct Injected Series 4.00in Stroke 4.130in B -20 cc Dish Platinum Series Pistons

Manley Performance is well-known for building strong engine components, and their Platinum Series pistons are a prime example of that commitment. If you're building a high-performance Chevy LT1 engine with direct injection, these pistons are designed to handle the demands of serious power. They feature a 4.00-inch stroke and a 4.130-inch bore, with a -20cc dish to help achieve your desired compression ratio.

These pistons are forged from domestic 2618 alloy, which is chosen for its superior strength and ability to withstand high temperatures and pressures. Manley also machines them with proven cam and barrel skirt profiles, which help generate power while being easier on your cylinder walls. The ring lands and grooves are held to strict standards to ensure a good seal, which translates directly to more power. Plus, Manley's unique fixturing process ensures the ring grooves are perfectly square to the piston skirts, a detail that matters for consistent performance.

Included with these pistons are premium chrome moly wrist pins, known for their durability. For those looking for even more robustness, Manley offers upgrades to 9310 or Turbo Tuff/DLC alloys. These pistons are a solid choice for professional engine builders and tuners who need reliable components for their builds. Please note that these pistons are not CARB approved and cannot be shipped to California.
