The kit is comprehensive, providing twelve pieces that fit the 283 through 383 engine range perfectly. Since they are built from corrosion-resistant chrome steel, you aren't just getting a quick fix, but a durable upgrade that stands up to the heat and grime of a working engine.

This 20-piece AeroBon kit includes M6*20mm stainless steel screws, making it a complete solution for upgrading your license plate frame, engine bay, or headlight mounts. Installation is straightforward, and because they are designed for stability, they provide a secure fit that looks much more professional than stock bolts.

Because these bolts offer a longer threaded bite length than the standard competition, you get a level of reliability that is often missing in cheap aesthetic upgrades.
