Description

The Vargas Turbo Technologies Crank Bolt Capture provides an essential layer of security for high-performance BMW engines by preventing the crankshaft bolt from loosening. Spun crank hubs on N55 and S55 platforms can lead to skipped valve timing and catastrophic engine failure; this capture kit addresses this by fully encapsulating the head of the factory crankshaft bolt and locking it in place against the crank hub. It is manufactured from 100% billet aircraft-grade aluminum and features a black anodized finish for durability. This kit is intended exclusively for 2011+ BMW models equipped with N55 or S55 engines. In rare instances where the capture plate does not align with the damper bolts, the installer may need to slightly adjust the torque on the crank bolt or install a new bolt to ensure correct clocking; due to the high torque specifications involved in these procedures, professional installation is strongly recommended. Weighing only 1.3 ounces, the capture plate adds virtually no rotational mass, maintaining engine balance. Unlike more invasive crank hub solutions, it requires no major engine disassembly and can be conveniently installed during routine services, such as a drive belt replacement.

MIA's Description

The Vargas Turbo Technologies Crank Bolt Capture is a billet aluminum security kit designed to prevent the crankshaft bolt from spinning loose on 2011+ BMW N55 and S55 engines. It functions by locking the existing crankshaft bolt to the crank hub using the vibration damper bolts, effectively mitigating the risk of the bolt backing out and causing potential timing and engine damage.
