BH610321L is a metric hex head bolt used in the axle and suspension assemblies of Land Rover Defender, Discovery, and Range Rover Classic models, with specific application from the bottom link mounting point. These fasteners secure critical suspension components including radius arms and link assemblies, where correct torque retention directly affects steering geometry and axle location. Using an incorrect or worn bolt risks joint movement, accelerated bush wear, and potential loss of axle control. Key Features Hex head bolt construction allowing standard spanner or socket installation Designed to meet OEM torque specifications for suspension joint integrity Direct replacement matching original Land Rover part BH610321L Check condition of corresponding nuts, washers, and rubber bushes when replacing - these are commonly worn on high-mileage vehicles Vehicle Fitment Fits Land Rover Defender (1986–2006 and 2007 onwards), Discovery 1 (1989–1998), and Range Rover Classic, all in axle and suspension applications, with noted fitment from the bottom link on Range Rover Classic.
