**Mounts are temporarily fastened together for installation. This is due to the amount of compression needed to seat the two mount halves together with the more rigid poly insert. Slight alignment may need to be done on installation. Mount halves will fully seat on install.** Poly insert may be black or red Works with stock steel engine mounts or our BPI-f10774 (included) New improved 70-81 Fb Mounts upgraded with new high-quality steel reinforced polyurethane inserts. Poly Motor Mount Inserts both restore worn mounts and reduce unwanted motor movement. Under high performance conditions, these Motor Mount Inserts reduce wheel hop and torque induced movement that can actually damage vehicle components. These polyurethane inserts are thoroughly tested to add support and stability to the OE motor mount design. Rated to 600+HP Improved design is much stronger and stable than factory motor mounts. Prevents excess engine movement and damage to other vehicle components. Made of HYPER-FLEX performance polyurethane. Resistant to under vehicle fluids: oils, coolants, road contaminants. **Original engine height will not be altered with these mounts** If using headers, ceramic coated headers are highly recommended AND/OR a heat shield or header wrap to keep heat away from the Poly mounts as excessive heat may cause the poly to melt or deteriorate.
