Compact Racing Shock Piston for Losi Models

These shock pistons are crafted using Delrin material, a unique design that enables the same pack on the downstroke. During the rebound, the shock oil applies pressure on the O-ring, slowing down the dampening and helping to prevent blow-by of the shock oil around the piston. The slots extend downward to slow the rebound, which is the recommended approach.

For optimal performance, it is recommended to use shock oils ranging from 300 to 400 CST, as this will provide increased pack. These shock pistons are designed to fit Losi-style shocks with a 0.116-inch center hole.

Manufactured by M2C Racing, the part number for these shock pistons is M2C9641.

The Delrin material used in the construction of these shock pistons is a key factor in their unique design and performance. Delrin, also known as polyoxymethylene (POM), is a highly durable and versatile engineering plastic that offers excellent dimensional stability, low friction, and resistance to wear and fatigue. This material choice ensures the shock pistons can withstand the demanding conditions encountered during use, providing reliable and consistent performance over time.

The shock pistons' design allows for the same pack, or compression, on the downstroke. This consistency in the piston's behavior during compression helps to maintain a predictable and controlled suspension response, which is crucial for optimal handling and performance in various off-road or high-speed applications.

On the rebound, the shock oil applies pressure on the O-ring, which helps to slow down the dampening process. This controlled rebound helps to eliminate the issue of "blow-by," where the shock oil can bypass the piston and escape around its edges. By maintaining the shock oil's intended path, the pistons effectively dissipate the energy and provide a smoother, more controlled rebound.

The downward-extending slots in the pistons further contribute to the slowed rebound. This feature helps to fine-tune the suspension's characteristics, allowing users to achieve the desired level of rebound damping to suit their specific requirements or preferences.

The recommended shock oil viscosity range of 300 to 400 CST (centistokes) helps to ensure the proper pack, or compression, of the suspension. By using oils within this viscosity range, users can optimize the suspension's responsiveness and performance, tailoring it to their riding conditions and preferences.

Finally, the shock pistons' compatibility with Losi-style shocks, featuring a 0.116-inch center hole, makes them a versatile and widely applicable solution for a variety of off-road vehicle applications. This compatibility allows users to easily upgrade or replace their existing shock pistons with the M2C Racing product, seamlessly integrating it into their existing suspension system.
