Mustang Negative Roll Kit

Tubular upper control arms for Mustangs, Falcons and Ranchero. The primary goal of a well designed suspension system is to keep as much of the tire patch in contact with the pavement, through any given situation (especially corners). Our tubular upper control arm geometry kit (NEGATIVE ROLL SYSTEM) does exactly that. How? By changing the length of the upper control arm and lowering the upper pivot point just the right amount, we are able to change your 1964-1973 Mustang's handling characteristics from a under steering nightmare to a slot car on rails.

How can this easy swap make such a dramatic change? Standard Mustang front suspension systems lean the top of the tire out of the fender during corning. This in turn lifts the inside edge of the tire off the pavement, decreasing the tire contact patch. This accounts for your Mustang's increased outside tire wear and poor handling characteristics (under steer). Simply stated under steer is when the car enters a corner and continues to go straight rather than negotiating the turn.

Global West's Negative Roll System changes your Mustang's geometry and handling characteristics by increasing the amount of tire that stays in contact with the pavement through the corner. Our suspension system tilts the inside edge of the tire down on to the pavement rather than allowing it to lift. This keeps the tire contact patch flat on the pavement, improves tire wear, and provides greater control at higher cornering speeds.

Global West's control arms are by far your best investment for your suspension.

Benefits and features:

1 .We take the guess work out of Mustang handling woes with correct length upper control arms. Fixed length control arms provide predictable handling characteristics over variable length upper control arms.

2. Round tube construction provides superior strength over standard stamped steel control arms.

3. Corrected ball joint angles are mandatory and considered a standard feature.

4. Upper tubular control arms have a limited life time warranty, (as long as you own your car) racing or not!

5. Billet cross shafts are standard components and also warranted.

6. Del-a-lum control arm bushings are considered to be the ultimate suspension bushing. Zero bind, zero deflection, fully grease able, and have a life time warranty (As long as you own your car).

7. An upper control arm relocation template is provided for easy measuring.

8. Upper ball joints are furnished with hardware.

9. Arms are pre-assembled and lubricated with synthetic grease.

10. Upper arms are powder coated gloss black.

11. Alignment information is included, which any alignment shop can handle.

Mustang Front Lower Control Arms

Global West offers two styles of lower control arms, stamped factory style and tubular. Both lower control arms feature spherical bearings on the frame side and new lower ball joints. A spherical bearing provides for smooth movement all through the suspension travel without bind or deflection. They are far superior over rubber or polyurethane bushings. The spherical bearings we use are also lined with a Teflon seal and bearing surface. This type of bearing does not require lubrication to operate properly.

Standard lower control arm features and benefits:

1. The lower control arms are modified by boxing in the arms. This is done by welding additional plates over a specific area of the arm.

2. Control arm bushings have been replaced with aircraft spherical bearings. This requires machining the control arm bushing location and installing special housings for the bearings.

3. New lower ball joints are also standard.

4. Control arms are shipped pre-assembled.

Tubular lower control arms are designed specifically for strength and the ability to service the control arm, both the lower ball joint and the spherical bearing are replaceable. The arms use a twin tube design and accommodate the stock sway bar and strut rod.

Tubular lower control arm features and benefits:

1. Control arms are built out of .125 wall seamless tubing (twin tube design).

2. Aircraft spherical bearings are utilized at bushing locations.

3. Lower ball joints are replaceable.( Note: These lower ball joints thread into the lower control arm). They are used heavily in the stock car industry.

4. Stock strut rods will bolt up.

Global West also offers Coilover Suspension kits for high performance use.
