Rigid collars are precision-engineered components featuring a specialized design, manufactured from tempered aluminum material. These products are specifically engineered for mass-production vehicles manufactured after 1990, with compatibility verified through real-world vehicle testing. With 1,000 compatible vehicle models available, installation is possible on virtually all automotive manufacturers' vehicles equipped with subframe architecture.
During automotive assembly, mass-production facilities operate under strict efficiency requirements where even seconds matter for productivity targets. The engine-mounted subframe assembly process involves hydraulic lifting systems that position components onto moving vehicle bodies along the production line. This critical assembly phase occurs within mere seconds of precision timing.
To facilitate rapid and reliable installation of heavy, vibrating main assemblies, automotive manufacturers worldwide intentionally oversized the mounting bolt holes relative to the fastening bolts. This engineering approach streamlines assembly procedures and enhances mass-production efficiency across global manufacturing operations.
While modern vehicle body rigidity has seen continuous advancement over recent years, the clearance gaps between bolts and their corresponding holes have remained largely unaddressed due to production considerations. These clearances generate low-frequency vibrations throughout the vehicle structure and represent a primary factor in compromising overall automotive rigidity.
