0.020 Oversize Piston Assembly for High-Mileage Briggs Animal Engines

Push your Briggs Animal engine further with the 555662 0.020 oversize piston assembly, a targeted solution for cylinders showing deeper wear patterns. By increasing the bore size, it reestablishes optimal piston-to-wall clearance, locking in compression that fuels aggressive launches and mid-range punch. This means less time lost to slippage and more time dominating the leaderboard.

• Power Recovery: Regains lost efficiency, turning high-mileage motors into race-ready beasts.
• Reduced Friction: Coated skirts minimize heat buildup, supporting extended high-RPM operation.
• OEM Precision: Matches factory specs for drop-in compatibility in LO206 builds.

From a technical standpoint, the 0.020 sizing pairs perfectly with honed cylinders, ensuring even ring seating and superior oil scavenging. Kart racers find it invaluable for seasonal overhauls, as it extends rebuild cycles and sharpens overall responsiveness. No more sluggish revs—enjoy the thrill of seamless power delivery that keeps you glued to the apex.

Think about track organization: this piston simplifies maintenance by promoting cleaner internals, reducing the need for frequent teardowns. In series where reliability trumps raw speed, it delivers both, helping you stay competitive without constant tweaks.

Frequently Asked Questions

Q: When should I upgrade to a 0.020 oversize piston?

A: You should consider this assembly when your cylinder bore shows signs of wear, scoring, or taper that exceeds factory tolerances. Using an oversize piston allows you to hone the cylinder back to a perfectly round, smooth surface, restoring proper compression and sealing.

Q: Is this piston assembly compatible with my stock LO206 engine?

A: This piston is designed for engine rebuilds where the cylinder has been bored and honed to accommodate the 0.020 oversize. Please ensure your engine builder has performed the necessary machine work to match this specific piston size before installation.

Q: Do I need to replace my rings when installing this piston?

A: Yes, this assembly is designed to work as a complete unit. When installing an oversize piston, it is critical to use the rings provided with the kit to ensure proper break-in, oil scavenging, and compression sealing against the newly honed cylinder wall.

Q: How does the coated skirt benefit my racing performance?

A: The specialized coating on the piston skirts is designed to reduce friction and heat buildup during high-RPM operation. This helps prevent scuffing and promotes engine longevity, allowing for more consistent power delivery throughout your race season.
