Lower Rear Trailing Control Arm - Left Or Right (Tubular W/ Polyurethane Bushings and Complete Hardware!) Comes with Four (4) 16mm Bolt Kits!The 1997/1998 vehicles use a 14mm bolt, the factory upgrades all of the repairs to this shipped 16mm size for longer life. A Ford/Lincoln repair garage would have had to enlarge the mounting holes to accommodate this larger size.These Arms Are Fabricated From Heavy Duty Tubular Steel, Cnc Machined Steel And High Quality Welds To Improve The Performance And Life Of These Arms For 10X Longer Than The Oem Units!The Arms Are Then Powder Coated To The Highest Standards To Protect The Parts From Harsh Particles On The Road And Oxidation Caused By Water, Salt (Nacl), Calcium Chloride (Cacl2) And Other Road Debris.We Sell These Arms In Four Versions, The First Is Factory Genuine Oem, The Second Is Tubular Steel Constructed With Oem Spec Rubber Bushings, Third Version Is Tubular Steel Arms With Polyurethane Bushings And The Fourth Version Is A Tubular Steel Arm With Super High Density Red Polyurethane Bushings.Benefits Of Polyurethane Bushings:For More Precise Handling And Firmer Control Installing Polyurethane Bushings Can Make A Massive Difference Because They Help To Maintain The Right Alignment Of Caster, Camber And Toe, Even On Rough Or Uneven Pavement. Another Advantage Of Polyurethane Bushings Is That They are Virtually Impervious To Oil And Other Road Contaminants. These Units Will Not Crush Down Or Wear Out Like Rubber Bushings, And Are Designed To Last The Life Of Your Vehicle. In Contrast, Rubber Bushings Are Often Bonded To A Metal Shell And Sleeve, And Function With A Twisting Action That, When Pushed To Its Limit, Binds Up Instead Of Rotating Freely Like Urethane Units. Rubber Bushings Can Even Induce Wheel Hop From The Spring-Like Action Of The Rubber Twisting Back And Forth.
