I'm looking for front shock absorbers with a height of 330mm and rear suspension units that are 280mm high, specifically designed with a slow release mechanism. These components are essential for enhancing vehicle stability and performance. Please provide detailed specifications, including materials, load capacity, and compatibility with common vehicle models. Additionally, I'd appreciate your pricing options, lead times, and any available warranty information. Thanks!
