Steeda's Sport Pro-Action combo kit puts together our Steeda Sport Springs and street adjustable upper strut mounts with our matched Pro-Action Shocks and Struts in one complete package.

If your budget allows, when lowering your 2005-2014 Mustang GT it makes both performance and financial sense to change the springs, shocks, struts, and upper strut mounts together. From a performance standpoint our Pro-Action shocks and struts are far superior to the factory units at properly controlling the higher spring rates of our lowering springs providing improved ride quality and control.

With the front springs mounted directly on the strut on the bottom and the upper strut mount on the top which has to be removed for installation, it makes financial sense to do all these components together at the same time saving you on labor costs.

Do the job right once and save money with our Pro-Action Sport Combo Kits.

Note: Springs will lower your Mustang 1" in the front and 1 1/4" in the rear.

Customer Reviews

Awesome Engineering, Lacking Instructions
The quality of engineering and the resulting performance is awesome. Dropped the rear at least an inch and really improved the stance. The tires stay planted better with improved hookup with WOT starts. However, the instructions do not include torque specs for all bolts and the shocks do not include any replacement rubber mounting grommets. You are expected to use the old grommets or buy a kit from KYB if you want to have new grommets. I have never replaced shocks of all different brands that came without the replacement grommets. I have not installed the struts yet. I couldn’t give five stars based solely on the poor instructions, lack of complete torque specs and rubber grommets.

Amazing handling wow!
Now this is the complete package! Handles like a true sports car should! Doesn't matter how much hp you're making if you can't plant it to the ground right?!

Steeda comes through
Had a question about the suspension setup and the customer reps were very knowledgeable and eager to help! Will definitely look forward to future mod purchases with these guys.

Suspension is the way to go
Really happy with the suspension setup now. Should have probably started adding these mods earlier but wanted to at least do some engine work first.
