The factory OEM front lower control arm uses rubber bushings that deflect under braking and cornering loads, allowing alignment geometry to shift dynamically and producing vague, inconsistent front-end feedback. The \u003cstrong\u003eSPL FLCA F8X\u003c\/strong\u003e replaces these bushings with FK Rod Ends and High Misalignment Spherical Bearings, giving precise, locked geometry response. The main arm is slotted for the exclusive electroless nickel-plated 4130 Chromoly Double Adjuster with 360-degree rotating clamps that eliminate jam nuts. Stainless steel roll center spacers are included to correct roll center height on lowered vehicles, and the street version includes the headlight aiming rod bracket.
