Supertech Block Guard for Honda K24

If you're building a Honda K24 engine for serious performance, you know that increased boost or nitrous can put a lot of stress on the cylinder walls. This Supertech block guard is designed to reinforce the open deck design of the K24 block, helping to prevent cylinder wall flex and distortion under high load. It's a well-built piece that adds crucial support right where it's needed most.

This block guard is made from solid aluminum and fits snugly between the cylinder sleeves. It essentially ties the sleeves together, creating a much more rigid structure for the entire bottom end. This added rigidity is key to maintaining proper piston ring seal and preventing catastrophic failure when you're pushing the engine hard. Installation involves removing the pistons and installing the guard before reassembling the engine, so it's a job best done during a full engine rebuild.
