Strut Upgrade Kit for Mustang (1994-2004)

Our K-Member is the foundation of the Griggs Racing front suspension system, providing the correct geometry, with superior rigidty and the highest strength to weight ratio. For 40 years we have continued revising and improving our design as tires, downforce and brakes have substantially increased loads and demand on the K-Member structure.

We offer both Soft (Elastomer) and Solid (Aluminum or Steel) motor mounts depending on your usage. Solid mounts reduce movement of the engine and transmission assembly, increasing shifting precision and a degree of increase in chassis rigiditiy.
If you have a properly balanced engine assembly, including flywheel and clutch, solid mounts can be used on the street, although you may feel minor harmonic vibrations at lower RPMs (for V8 engines, this is usually around 2100 RPMs).

Based upon the narrow tire width you indicated, you might consider running a larger tire for enhanced performance.

If you do increase your front tire width, will need to do one of the following:
     1) Modify your existing front fenders
     2) Replace them with a wide fender option

If neither of these options are desirable, feel free to decline our suggestion.

Based upon the tire width you indicated, you will need to do one of the following:
     1) Modify your existing front fenders
     2) Replace them with a wide body option

If neither of these options are desirable, please return to the "Select Tire Width" step, using the button below and left to select a narrower tire width.

High quality AN fittings, hose and adaptors to connect your powersteering pump to your rack and cooler

Keep your power steering system cool under high loads, increasing life span and mitigating potential damage

A Bumpsteer Kit is essentially a tie rod end set that is adjustabable in height. When properly adjusted, this helps negate steering angle changes during vertical motion of the suspension

Required Item.

Single Adjustable struts have a fixed compression and rebound valving. Double Adjustable struts have both adjustable compression and rebound. All struts are sport valved and can be used for either street or competitive use.

Please note that these do not come with springs or related hardware which is offered in the following steps.

High-grade progressive bumpstops you must install on the shocks.

Manufactured by one of the premium spring winders in the United States.

We offer Coil-Over Hardware Kits for Front Struts with a body diameter of 54mm (OE, Koni, Monroe, Tokico, etc...) and the smaller 50mm diameter (Bilstein). The struts we sell, are the 54mm variant.
Spring mounting hardware only, does not include Struts, Springs, or Caster/Camber plates.

Strut cars need camber plates to allow for proper alignment and permits precision alignment, provides more positive caster, improves straightline stability, improved cornering power and improved tire wear.
