UMI's LSX poly engine mounts bridge the gap between stock GM mounts and race‑oriented solid mounts, offering a higher‑performance but not fully solid option for LS swaps. Dimensions match the GM 22179268 mount used in 1998–2002 GM F‑Body cars. These mounts are recommended for use with UMI 2320, 2321, 2330 and factory K‑members, as well as 2406 and 2410 LS swap mounts in other platforms.
