Rear Parabolic Leaf Spring

The Dobinsons L21-182-RP is a rear parabolic leaf spring engineered to deliver superior ride quality, durability, and load-handling performance for a variety of vehicle types. With over 60 years of manufacturing expertise, Dobinsons offers custom-designed options for 4x4s, trucks, commercial vehicles, and utility vehicles, tailored to specific load and height requirements. Key features of these leaf springs include their construction from SUP9 silicon manganese spring steel for long-lasting performance, and ISO9001:2008-certified manufacturing with tapered, thinned leaf ends for balanced stress distribution. They are also shot-peened and scragged to prevent sagging and increase service life. Additional features like military-wrapped eyes enhance safety in case of main leaf failure, while anti-friction inter-leaf liners and high-strength alignment clips with nylon insulators and Nyloc nuts contribute to smoother, quieter operation and reduced wear. Fitment information indicates that this specific leaf spring is designed for vehicles such as the Isuzu D-Max (2012+ and 2020+) and Mazda BT-50 (2020+). It provides a 50mm lift with up to 70KG of rear end load and is rated as a comfort spring for an empty bed. Some retailers note that this product may not fit all vehicles entered, and it is recommended to verify fitment with the sales team to reduce the risk of ordering the wrong product. If a fitment issue arises despite confirmation from the sales team, returns may be accepted under specific conditions, and items must be unused and uninstalled.
