Tuningsworld Rear Tubular Upper & Lower Control Arm Kit for Ford Mustang 1979–2004 — Powder-Coated Steel, Polyurethane Bushings

Tuningsworld's rear tubular upper and lower control arm kit is a direct-fit replacement for many 1979–2004 Ford Mustang models, supplying powder-coated tubular steel arms with polyurethane bushings and all necessary hardware for improved rear suspension geometry.

This kit is engineered to refresh and strengthen the rear suspension on classic Mustangs and related models. It replaces worn or corroded stamped pieces with tubular, welded steel arms and firmer poly bushings that resist deformation over time. The kit comes complete with upper and lower control arms, bushings, bolts and nuts, plus Tuningsworld lifetime technical support and a 1-year limited warranty for quality-related issues.

Will this control arm kit fit my Mustang or Capri?

These arms are designed to fit Ford Mustang 4‑cyl, 6‑cyl, and 8‑cyl (GT or LX) model years 1979–2004, Mercury Capri 1979–1986, and Ford Cobras 1993–1998. Note the exception: it will not fit Mustang Cobras from 1994–2004 that use independent rear suspension. Verify your model year and rear suspension type before ordering.

• Compatible: Mustang 1979–2004 (4CYL, 6CYL, 8CYL GT/LX)
• Also fits: Mercury Capri 1979–1986; Cobra 1993–1998
• Not compatible: Mustang Cobra 1994–2004 with independent rear suspension
• Direct-replacement design for factory mounting points

How do polyurethane bushings and tubular steel change handling?

Polyurethane bushings are firmer than rubber, reducing unwanted compliance and improving repeatable suspension geometry under load. The tubular steel construction is stronger and more rigid than many stamped OEM arms, helping maintain alignment under cornering and resisting deformation at higher power levels.

• Firmer poly bushings for more consistent camber and toe settings
• Tubular welded steel resists bending and fatigue better than stamped arms
• Improved cornering precision and vehicle stability
• Handles power levels up to approximately 400 horsepower

What does the kit include and is installation straightforward?

The package contains both rear upper and lower control arms finished in corrosion-resistant powder coat, preinstalled polyurethane bushings, and the required bolts and nuts for assembly. Installation follows factory mounting points; a competent DIYer with common tools can complete it, but an alignment after installation is strongly recommended.

• Left and right upper control arms and lower control arms
• Polyurethane bushings preinstalled or included
• All necessary bolts and nuts for rear mounting
• Lifetime technical support and 1-year limited warranty

Will these arms last longer than stock and what maintenance is needed?

The powder-coated tubular steel resists rust and the polyurethane bushings outlast rubber in most conditions, offering longer service life and steadier alignment. Periodic inspection of bushings and hardware torque is recommended; replace bushings if extreme wear or chemical damage is observed.

• Durable powder-coat finish reduces corrosion risk
• Poly bushings resist oil and ozone better than rubber
• Inspect hardware torque and bushing condition periodically
• Replace components as needed to preserve alignment and handling

Who is this for: Tuningsworld's rear upper and lower tubular control arm kit is aimed at owners of classic Ford Mustangs, Mercury Capris, and compatible Cobras looking to restore or upgrade rear suspension strength and geometry. It's appropriate for street-driven cars seeking improved handling and longevity, weekend track cars up to roughly 400 horsepower, and anyone replacing worn or corroded rear suspension components who wants a direct-fit, durable solution backed by support and warranty.
