Silv-O-Lite 3523HC05K1 GM LS 6.2L Flat Top Hypereutectic Piston Kit 0.020 in. Oversize

The Silv-O-Lite 3523HC05K1 is a complete hypereutectic piston kit designed for the GM 6.2L LS3 V8 engine (manual transmission applications). This kit includes pistons with rings and covers the 0.020 in. (0.5mm) oversize bore specification of 4.085 in., making it an ideal choice for engine rebuilds requiring a first oversize bore.

Key Features:

• Hypereutectic aluminum construction — high-silicon alloy delivers greater strength along with improved scuff and seizure resistance compared to standard cast pistons
• Flat top piston design — engineered to maintain proper compression ratios for the GM LS3 6.2L platform
• M42 anti-friction coated skirts — dry film lubricant coating reduces friction and wear during initial break-in and throughout engine life
• Floating offset wrist pin — reduces piston slap noise and provides more even load distribution on the pin and rod
• Reinforced top lands — resist cracking in the crown area where operating temperatures are most severe
• Diamond-finished skirts — proprietary skirt finishing process provides the most consistent skirt geometry in the industry
• Kit includes rings — complete piston and ring set for a straightforward rebuild

Specifications:

• Bore Size: 4.085 in. (0.020 in. / 0.5mm oversize)
• Stroke: 3.622 in.
• Piston Style: Flat Top
• Material: Hypereutectic Aluminum (390 alloy)

Silv-O-Lite pistons are manufactured by United Engine & Machine Co. (UEM), bringing decades of engineering experience to every piston produced. This kit delivers OE-quality fitment and durability for street rebuilds and mild performance applications on the GM LS3 6.2L platform.
