Wiseco K0235X6 Forged Piston Set 4.125 Bore -10cc Dish 6.2L LT1 Gen V Corvette

Vehicle Fitment

• 2014-2019 Chevrolet Corvette Stingray C7 (6.2L LT1 V8, Gen V Direct Injection, RWD)
• 2016-2024 Chevrolet Camaro SS (6.2L LT1 V8, Gen V Direct Injection, RWD)
• 2020-2024 Chevrolet Camaro LT1 (6.2L LT1 V8, Gen V Direct Injection, RWD)

Fitment Notes

• Designed specifically for Gen V LT1 6.2L direct-injected engines only - not compatible with Gen III/IV LS engines
• This is a 4.000" stroker application piston - designed for use with aftermarket 4.000" stroke crankshafts and 6.125" connecting rods; not for stock 3.622" stroke builds
• Does not fit the supercharged LT4 (Camaro ZL1 / Corvette Z06) or LT5 (Corvette ZR1) - naturally aspirated LT1 only
• Compression ratio of 11.7:1 calculated at 0 deck height with a 0.051" (1.3mm) head gasket and 59cc combustion chamber
• Requires cylinder boring/honing to 4.125" before installation - verify bore size with a machine shop before ordering
• Piston pin wall thickness is 0.200" - uses Spirolox retainers (included); not compatible with OEM stock rod pins
• Corvette Z51 dry-sump and standard wet-sump Camaro LT1 blocks are both supported

Features

• Forged from 2618 aerospace-grade aluminum alloy for superior tensile strength, heat resistance, and detonation tolerance in high-output builds
• ArmorGlide® skirt coating reduces piston-to-wall friction, lowers piston noise, and improves seizure resistance during cold starts and oil-loss events
• ArmorPlating™ thermal protection applied to the crown and ring grooves for added defense against detonation damage and ring micro-welding
• Anti-detonation and pressure seal grooves machined into the ring land for enhanced ring seal and reduced blow-by at high cylinder pressures
• -10cc dish crown profile tailored for 4.000" stroker builds using 59cc Gen V LT1 combustion chambers at 11.7:1 compression
• Engineered, forged, and machined in the USA at Wiseco's Mentor, Ohio facility

Product Description

The Wiseco K0235X6 is a Professional Series forged piston set engineered for serious Gen V LT1 6.2L stroker builds using a 4.000" stroke crankshaft and 6.125" connecting rods. At 4.125" (+0.0602" oversize) with a -10cc dish crown, these pistons deliver 11.7:1 compression at zero deck height with a 0.051" head gasket in the LT1's 59cc combustion chambers - making this kit ideal for high-output naturally aspirated or mild forced-induction stroker combinations in the C7 Corvette and sixth-generation Camaro SS and LT1 trim.

Built from 2618 aerospace-grade aluminum and featuring both ArmorGlide® skirt coating and ArmorPlating™ crown protection, these pistons are designed to handle the elevated cylinder pressures and thermal loads generated in high-displacement, high-compression race and performance builds. The included GFX premium ring set with gas-nitrided top rings ensures consistent sealing and long service life. Builders should note this piston set is for stroker applications only and requires matching 4.000" stroke crankshaft and 6.125" connecting rods - it is not a drop-in replacement for stock LT1 rotating assembly components.
