Steel Cylinder Spacer Plate for Ø 77 mm Cylinders – Fiat 500 F/L

Maximum rigidity and stability: the steel Fiat 500 spacer plate

The steel piastra sottocanna Fiat 500 represents the technical evolution for the most extreme tuning of the twin-cylinder engine. Compared to light alloy versions, the use of steel offers superior mechanical resistance, making this component essential for high-performance engines operating with high compression loads. This plate is specifically designed to house oversized cylinder kits with a 77 mm diameter, ensuring a stable and long-lasting coupling between the crankcase and the cylinder liners.

Structural reinforcement and millimetric precision

The 10 mm height of the plate serves not only as a technical spacer but also as a true reinforcement element for the entire engine block:

• Prevention of Failure: Steel, thanks to its high elastic modulus, evenly distributes the stresses generated by the head studs, minimizing the risk of cracks in the original cast iron block.

• Geometric Correction: The 10 mm thickness is ideal for balancing the height of the liners when using longer connecting rods or increased stroke crankshafts, allowing the desired compression ratio to be achieved without interference between piston and head.

• Dimensional Stability: Unlike other materials, steel maintains exceptional flatness even in the presence of very high operating temperatures, ensuring that the base gasket seal remains perfect over time.

Detailed Technical Specifications:

• Cylinder Compatibility: For oversized Ø 77 mm cylinder kits.

• Housing Hole Diameter: Ø 83 mm, machined for absolute precision.

• Height (Spacer): 10 mm.

• Material: High-resistance steel.

• Vehicle Application: Fiat 500 F and Fiat 500 L.

The ultimate choice for racing preparation

For high-level tuning that accepts no compromises, this piastra sottocanna Fiat 500 is the component that makes the difference. Its structural robustness protects the integrity of the engine, allowing performance to be pushed beyond conventional limits in total safety. The 83 mm housing holes ensure perfect insertion of the liners, eliminating any unnecessary mechanical play. If you are assembling an engine destined to last and to win, this steel plate is the solid foundation upon which to build your mechanical success.
