Piston 1.00 mm oversize, Pre-topped, High Performance

Oversize 1.00 mm, High Performance, pre-topped, replacement pistons to suit Toyota 1HZ-T engines. These pistons have alfin inserts in the top ring grooves, are pre-topped 0.15 mm in compression height, the body has been phosphate, crowns are anodised and coated with Cerakote piston coat (V-136), skirts are coated with Cerakote Micro Slick (P-109).  They are oil gallery cooled and are supplied with the required oil squirters.  They have 50% thicker crowns, extra top ring land clearance, increased under-crown radius and improved skirt and boss designs – no struts.  Top ring grooves have been moved down 2.5 mm.  100% Ultrasonic tested for high-integrity Alfin insert bonding. Made from AC8A-T6 Eutectic aluminium.  Piston crown weights optimised to maintain piston rock near or at T.D.C.  Top ring 2.0 mm 1/2 keystone, 2nd ring 2.0 mm, Oil ring 4.0 mm, Gudgeon pin diameter: 33.0 mm.

Sold as an engine set including pistons, pins, circlips and squirters.

We offer the following 33mm pin, 1HZ-T/1HD-T conrods:  High quality Aftermarket Conrod Set - CRTO350 or High Performance I-Beam Conrod Set - CRTO350B.

We recommend adding our Performance Ring Sets with Gapless Second Ring Technology – RSPTO350.1.00

(Cerakote® V-136 Piston Coat and Cerakote® P-109 Microslick coatings are applied in Australia)

Cerakote® V-Series High Temperature Ceramic Coatings are designed to protect metal substrates in high temperature applications. Cerakote V-Series High Temperature products are practical, performance-based coatings intended for exhaust systems and engine components. Additionally, Cerakote V-Series coatings are durable, resistant to thermal shock and designed to withstand extreme use temperatures of up to 1800°F - 980°C.  This helps to maintain even heat distribution across the crown, which reduces softening and premature failure from extreme temperature hot spots.  Reduced heat loss to the piston equates to better fuel burn rates, and increased power and fuel economy.

Cerakote® P-109 Microslick Dry Film Lubricant provides a low friction surface for metal-on-metal contact. This P-109 Microslick coating is formulated to withstand extreme temperatures (1,200°F - 648°C). This makes the coating ideal for pistons and other wear components in high temperature systems, and P-Series coatings maintain excellent adhesion even after repeated thermal cycling. These coatings provide superior protection again high wear, galling and corrosion. It will help prevent piston scuffing in the bores in most marginal lubrication conditions.
