Eibach Pro-Kit for 79-93 Ford Mustang Coupe 4 & 6 cyl (Inc. Turbo & SVO) / 94-04 Mustang Coupe 6 cyl

The Eibach Pro-Kit 3518.140 is a performance lowering spring set designed for 1979-1993 Ford Mustang Coupes with 4- or 6-cylinder engines, including Turbo GT and SVO models, plus 1994-2004 Mustang Coupes with 6-cylinder engines. It also fits select 1979-1984 Mercury Capri models. This kit drops the front by 1.2 inches (30mm) and rear by 1.0 inch (25mm) to sharpen cornering, cut body roll, and deliver a planted stance without sacrificing ride quality.

Key Features

  • Precise Lowering: Front 1.2" (30mm) drop, rear 1.0" (25mm) for balanced ride height on Fox Body and SN95 V6 Mustangs.
  • Progressive Spring Rate: Combines comfort on streets with firm control during hard driving and track use.
  • High-Strength Construction: Made from CrSi spring steel, shot-peened and heat-treated for 10.0% higher tensile strength than chrome-silicon.
  • Improved Dynamics: Reduces nose dive, squat, and roll for quicker steering response and neutral handling.
  • Direct Bolt-On Fit: Engineered to work with factory struts/shocks and mounts—no modifications needed.

Product Notes

  • Compatible with stock or performance dampers; pairs well with Eibach sway bars or shocks.
  • Retains full suspension travel and daily drivability.
  • Ships in protective box: 21" x 7" x 7" dimensions, net weight 26 lbs.

Installation Notes

  • Professional installation recommended.
  • Bolt-on replacement using OEM upper/lower mounts; 2-4 hours with standard tools.
