Rattle Flapper Repair Kit for BMW N55 18539880002 11657636426 3.0L

 High-Quality 

Rattle Flapper Repair Kit 

Fits BMW with N55 3.0L Engines

Designed to eliminate the common wastegate rattle issue, this kit is an excellent solution to restore proper turbo operation without replacing the entire unit.

Unlike most kits on the market made from standard 304 stainless steel, our kits are manufactured from high-grade 2520 stainless steel.
This material offers significantly better resistance to high temperatures and corrosion, making it ideal for demanding automotive applications—especially in turbo and exhaust systems. 2520 stainless steel maintains its strength and structural integrity under extreme heat, which helps prevent warping, cracking, or premature wear, ensuring longer service life and improved performance.
