You can buy the "Upgrade your block" service to send us your engine block ( without pistons, rods & crankshaft ) to milling and install the engine block guard.

The Use and Benefits of a Block Guard in Open Deck Engines

A block guard is an aftermarket reinforcement component designed to support the cylinder walls in open deck engine blocks. Open deck designs typically offer less structural rigidity around the cylinders because of the open space between the cylinder walls and the outer engine block. This design is beneficial for cooling but becomes a weakness under high-performance conditions due to potential cylinder wall flexing, cracking, or even failure.

La instalación de un block guard rellena el espacio abierto alrededor de los cilindros con un inserto de alta resistencia —normalmente de aluminio o acero— que aporta una mayor estabilidad y evita el movimiento de las paredes de los cilindros. Esto es especialmente importante en aplicaciones con alta presión de soplado o alta potencia, donde las presiones en los cilindros aumentan significativamente.

Key Benefits:

• Improved structural integrity of the engine block under stress.

• Prevents cylinder wall distortion, which can lead to head gasket failure or engine damage.

• Enhances reliability in forced induction setups (turbo or supercharged engines).

• Permite mayores niveles de soplado y una puesta a punto más agresiva con menor riesgo.

• Extends engine lifespan in motorsport or performance street use.

In summary, a block guard is a crucial upgrade for anyone looking to push the limits of an open deck engine, offering durability and peace of mind in extreme performance environments.

*El block guard diseños no se envían porque son diseños industriales, y el diseño y las horas de trabajo de este producto son extremadamente elevados. Hay disponible una opción de servicio para mejorar tu bloque, que incluye no solo el mecanizado en nuestras máquinas CNC, sino también la instalación del block guard con las tolerancias de apriete correctas*
