Steeda Stage 1 Drag Pack (555-4457) - 2015–2026 Mustang GT/V6/EcoBoost
Take your Mustang from the street to the strip with the Steeda Stage 1 Drag Pack—a proven suspension package designed to deliver maximum traction, quicker launches, and reduced wheel hop. Featured on Steeda’s own world-record-setting 2018 Mustang GT, this kit has the pedigree and performance you need to shave time off your ETs while maintaining excellent street manners.
The Stage 1 Drag Pack combines three of Steeda’s most effective drag racing upgrades: Drag Springs (555-8231), Pro-Action Adjustable Rear Shocks (555-8156), and the Stop the Hop Enthusiast Kit (555-4456). Together, these components create the ultimate foundation for consistent, powerful launches without unwanted chassis movement.
What’s Inside the Kit
- Drag Springs (555-8231) – Optimized for rear traction when paired with coilovers up front. Helps plant your Mustang for harder, straighter launches.
- Pro-Action Adjustable Rear Shocks (555-8156) – Engineered with Steeda’s proprietary valving, offering adjustable rebound damping at the twist of a knob for perfect street-to-strip versatility.
- Stop the Hop Enthusiast Kit (555-4456) – Tackles IRS movement with four key components:
- IRS Subframe Alignment Kit (555-4438) – CNC-machined Delrin inserts to square up the rear subframe and limit chassis movement under load.
- IRS Subframe Bushing Support System (555-4437) – Patented billet aluminum inserts filling factory voids to stop up-and-down subframe movement.
- Chrome-Moly IRS Support Brace (555-5754) – A 5-point bolt-in brace tying the subframe directly into the chassis for maximum strength.
- Rear Lower Control Arm Spherical Bearings (555-4117) – Eliminates deflection, improves responsiveness, and ensures tires hook immediately under power.
