These lightweight steel jack plates feature 5 inches of extended webbing to help keep springs in place and to prevent unwanted chassis changes on the track under race conditions. The special 3/4", -10 welded spud allows the plate to be locked to a weight jack bolt with a jam nut to help eliminate spring-to-jack bolt misalignment and spring binding during normal suspension travel.  These plates are perfect for Sport Mods with an extreme left rear hike.
