Front Suspension Kits

What's Included in a Front Suspension Kit

A complete front suspension kit bundles the major front-end components into one matched package, so you're not sourcing parts one piece at a time. What's included varies by kit and platform, but most systems combine the following core parts:

• Tubular upper and lower control arms for added strength and clearance
• Spindles matched to the arm geometry and brake package
• Coilover or shock assemblies, often with adjustable damping
• Front sway bar to control body roll
• Crossmember or K-member to mount the assembly to your chassis
• Rack-and-pinion or steering components for updated response
• Mounting hardware, bushings, and instructions

Some kits ship as bolt-in systems for a specific year and model, while others are weld-in setups meant for a custom or pro-touring build. Checking exactly which components a kit includes tells you what else you'll need to finish the job, such as brakes, springs, or an alignment. When you're comparing kits, match the parts list to your platform and your power and handling goals.

Independent Front Suspension and Mustang II Kits

An independent front suspension (IFS) kit replaces an older straight-axle or tired factory front end with modern geometry that sharpens steering, ride, and cornering. The Mustang II front suspension kit is the most popular IFS layout for street rods and classic builds, and All American Billet offers Mustang II IFS systems with tubular control arms in both coilover and air bag versions. If you want to understand the geometry behind these systems, our Mustang II upper and lower control arms guide breaks down how arm length and mounting points affect alignment. For early Chevy platforms, Heidts builds the Superide II IFS, a complete front subframe that bolts modern handling under classic sheet metal. These kits give you tubular upper and lower control arms, a matched crossmember, and coilover mounting, so you can dial in stance and handling on a proven platform.

Staged Front End Kits for Street and Drag

A staged front end kit lets you buy the exact level of upgrade your build needs, from a mild street setup to a full drag-race package. UMI Performance builds staged front suspension kits for the 1993-2002 GM F-Body, covering the Camaro and Firebird in both LS1 and LT1 applications. The kits run from Stage 1 through Stage 5, so you can start with control arms and bushings and work up to a complete front end with springs, sway bars, and matched hardware. Street versions focus on grip, ride, and cornering for a car you drive often, while drag versions are tuned for weight transfer and consistent launches at the track. Because the stages share a common design, you can upgrade in steps over time instead of buying everything at once.

Coilover, Air Bag, and Stock-Style Options

Your shock and spring choice sets how a kit rides and adjusts, and most front suspension kits come in coilover, air bag, or stock-style shock configurations. Coilover setups combine a coil spring and shock in one adjustable unit, giving you ride-height and handling control for street and track use. Air bag systems trade the coil spring for an adjustable air spring, so you can raise the car to clear driveways and lower it for stance when parked. Detroit Speed offers its SpeedMAX front suspension systems for the 1973-1987 GM C10 pickup with non-adjustable, single-adjustable, and double-adjustable shock options, so you can pick how much damping tuning you want. Whichever route you choose, plan on setting alignment afterward. Our guides on caster and camber and front end alignment tools walk through the settings that keep the car tracking straight. If you're lowering the car, pair the kit with matching lowering kits for the rest of the stance.
