Precision CNC laser cut and CNC folded from .250 cold roll plate steel. These Street Rod engine mounts are for installing the 2015-up Gen V LT series engine into any street rod or hot rod frame configuration. They are slotted for adjustment with engine placement in the engine compartment. Most street rod engine mounts only allow you to position the engine in one location, not allowing you to change transmissions in the future without major reconstruction of the transmission cross member. These mounts will allow you to move the engine forward or rearward with up to 3 inches of travel. These are offered as just the engine mounts, or a complete engine mount package. The isolators in the mount package are hyper-flex polyurethane. Designed with adjustable holes in the engine mounts and the frame mounts. Using the inner holes on the frame tabs these mounts are designed to fit frame widths of 19.125", 21.00", 22.875", and 24.75". Using the outer holes on the frame tabs these mounts are designed to fit frame widths of 21.125", 23.00", 24.875", and 26.75". The frame side mount can be trimmed up to an inch per side allowing these to fit chassis from 19.125" to 26.75" inside frame width. Welded and cooled in a jig to retain precision alignment. Grade-8 hardware included.
