Marlin Crawler and Inchworm have been working together for well over a decade. As the first exclusive distributor of Inchworm Single & Dual Case setups, we have been supplying our Heavy Duty adapter components and assembling transfer case products for Inchworm since the mid 2000’s. We are once again excited to be the exclusive builder and distributor for Inchworm products!

Made from 1/2″ thick USA billet aluminum, IG31’s multi transmission pattern allows for this kit to fit a large range of manual and automation transmissions, allowing for future upgrades or changes in drivetrain or use. Additionally, IG31 has a clockable feature allowing for 0° or 10° rotation options.

Kit includes Adapter Plate, Seal Adapter with transmission output seal (Marlin Crawler EcoSeal where applicable), and hardware kit.
