This movement repeatedly loads and unloads the tires creating wheel hop that:\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e• Destroys traction\u003cbr\u003e• Hurts 60-foot times\u003cbr\u003e• Slows

does.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eThe BK Racing Solid Billet Upper Engine Mount was designed specifically to eliminate this drivetrain movement and dramatically improve traction consistency and launch stability.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eWhy Solid Billet Mounts Work Better Than Polyurethane Inserts\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eMany aftermarket “performance mounts” still rely on polyurethane inserts or partial-solid designs that continue to flex under heavy load and eventually wear out over time.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eThe BK Racing fully solid billet design creates a direct mechanical connection between the drivetrain and chassis for maximum rigidity and power transfer without the unwanted compliance found in rubber or polyurethane mounts.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eThe result is:\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e• Dramatically reduced
