LS Swap Motor Mount Brackets

The Xcessive Manufacturing Motor Mount Brackets are engineered to facilitate the installation of an LS engine into the Lexus IS300 chassis. Constructed from steel plate to enhance durability and minimize the risk of cracking under the torque of a V8, these brackets are manufactured entirely in-house, ensuring quality control throughout the design, fitting, forming, welding, and powder coating processes. The general fitment design incorporates slotting for front-to-rear alignment and oil pan clearance. These mounts are intended to pair with shorter IS200 (1GFE) rubber isolators or Xcessive Manufacturing's 3.4" tall urethane mounts, which are highly recommended for handling the torque of an LS engine. For transmission compatibility, Xcessive Manufacturing offers a urethane transmission mount adapter designed to convert a TR-6060 transmission for a bolt-in fitment with their IS300 steel transmission cross member. Fitment testing was conducted using a Moroso oil pan (#20146). While other front sump oil pans may be compatible, their fitment has not been confirmed by Xcessive Manufacturing. It is important to note that these mounts are a performance upgrade and may increase engine noise transmitted to the chassis. Furthermore, these specific mounts DO NOT fit the USDM IS300 JCE10 chassis; they are intended for JDM applications.
