Scott’s Hotrods – About Our IFS

Scott’s IFS Is NOT a Mustang II Front Suspension

There is a common misconception in the hot rod industry that every aftermarket independent front suspension is some variation of a Mustang II. Scott’s Hotrods IFS is not a Mustang II suspension.

Scott’s Hotrods developed its own proprietary independent front suspension system around the needs of modern hot rods, classic cars and custom trucks. Rather than adapting lightweight suspension components originally designed around another vehicle, Scott’s engineers the crossmember, control arms, steering, spindle configuration, shock placement and suspension geometry to work together as a complete system.

The result is a heavy-duty, performance-oriented independent front suspension engineered for modern horsepower, modern brakes, wider performance tires and the way today’s custom vehicles are actually driven.

Purpose-Built Scott’s Suspension Geometry

Designed as a Complete Suspension System

A properly engineered IFS is much more than a crossmember and a pair of control arms. Control-arm length, mounting locations, spindle geometry, caster, camber, anti-dive, steering-rack position and shock placement all affect how the suspension behaves as the vehicle travels down the road.

Scott’s proprietary IFS geometry was developed to provide predictable handling, proper suspension travel and excellent road manners in everything from comfortable street cruisers to aggressive Pro Touring and high-horsepower performance builds.

Rather than relying on a universal suspension package and adapting it to dozens of unrelated vehicles, Scott’s engineers its IFS around the application and intended vehicle configuration.

Why choose Scott’s Hotrods?

Massive 1-1/8″ x .250-Wall DOM
Tubular Control Arms

Scott’s doesn’t build suspension components to be as small or lightweight as possible. Our tubular control arms are manufactured from 1-1/8″ OD x .250-wall seamless DOM tubing, providing exceptional strength for serious street and performance applications.

The unequal-length upper and lower control-arm design works with Scott’s proprietary suspension geometry to control camber throughout suspension travel, while heavy-duty construction provides the confidence required for modern engines, brakes, tires and real-world driving.

These aren’t lightweight Mustang II control arms repurposed for a heavier vehicle. They’re Scott’s control arms built for Scott’s IFS.

Heavy-Duty One-Piece IFS Crossmember

The foundation of Scott’s IFS is a substantial one-piece crossmember manufactured from 2″ x 4″ x 3/16″-wall rectangular tubing.

Scott’s does not use a lightweight three-piece crossmember that relies on separate components to create the suspension structure. The one-piece design provides a strong foundation for the control-arm mounting points, steering system and suspension loads while creating a rigid connection between the vehicle’s frame rails.

 

Positive Upper Control-Arm Adjustment
No T-Bolt Sliders

Scott’s IFS does not rely on T-bolt slider-style upper control-arm adjustments. Instead, Scott’s uses adjustable upper control arms that allow alignment changes to be made through the suspension components themselves.

This provides a secure, positive mounting arrangement while allowing the caster and camber adjustments required to properly align the finished vehicle.

Built-In Anti-Dive

Scott’s IFS incorporates anti-dive geometry into the upper control-arm mounting locations to help control excessive front-end dive during braking.

Rather than simply mounting the upper control arms parallel to the chassis because it’s easier to manufacture, their mounting geometry is engineered as part of the complete suspension system. Under braking, the suspension geometry helps resist excessive compression at the front of the vehicle, improving stability and driver confidence.

Heavy-Duty, Serviceable Suspension Components

Scott’s IFS utilizes oversized, serviceable ball joints and heavy-duty spindle assemblies selected around the demands of modern custom vehicles.

Serviceability matters. Suspension components are wear items, and Scott’s designs its systems around components that can be inspected, maintained and replaced when necessary rather than treating the suspension as a disposable assembly.

 

Modern Rack-and-Pinion Steering

Scott’s IFS incorporates rack-and-pinion steering into the suspension design, providing precise steering response and clean packaging compared with many original steering-box and linkage systems found beneath classic vehicles.

Depending on the application, Scott’s offers power and manual rack-and-pinion configurations. The steering rack is positioned as part of the suspension geometry—not simply mounted wherever it happens to fit—because steering-rack location plays a critical role in proper steering behavior throughout suspension travel.

Adjustable Coilover Suspension

Scott’s standard IFS systems use Aldan American single-adjustable coilovers, providing ride-height adjustment and control over shock damping.

Spring rates are selected around the vehicle and application rather than treating every classic car or truck as if it weighs the same. The combination of proper spring rate, shock control and Scott’s suspension geometry provides a front suspension that can be tuned around the way the finished vehicle will actually be driven.

SuperSlam Airbag IFS

For customers looking for an ultra-low stance and adjustable ride height, Scott’s offers its SuperSlam IFS using air springs and externally mounted shocks.

This is not simply a standard coilover IFS with the coilover removed and an airbag installed in its place. The SuperSlam configuration is engineered around the different packaging and suspension-travel requirements of air suspension, allowing Scott’s to achieve an aggressive stance while maintaining proper suspension function.

Modern Disc Brake Options

Modern suspension deserves modern braking capability. Scott’s IFS systems are designed around modern disc brakes with multiple configurations available depending on vehicle weight, wheel size, horsepower and intended use.

From comfortable street-driven hot rods to high-horsepower Pro Touring vehicles, Scott’s can configure the braking system around the demands of the finished vehicle rather than forcing every application into the same brake package.

Grade 8 Hardware — 5/8″ and Larger Where It Matters

Scott’s doesn’t compromise the suspension with undersized hardware. Our IFS systems utilize 5/8″ and larger Grade 8 hardware throughout critical suspension mounting locations.

One Scott’s IFS Philosophy — Multiple Applications

Scott’s proprietary IFS technology is available across a wide range of products, including Weld-On IFS systems, vehicle-specific Bolt-On IFS kits, Spring Pocket Replacement IFS systems, Cab-Over and specialty applications, 1-Ton IFS systems and complete Scott’s Hotrods chassis.

Although mounting requirements vary by application, the philosophy remains the same: heavy-duty construction, properly engineered geometry and components designed to work together as a complete suspension system.

Designed & Manufactured by Scott’s Hotrods

Scott’s doesn’t simply assemble an IFS from components purchased from other suspension manufacturers. Our engineering, CNC machining, fabrication and TIG welding capabilities allow us to manufacture and control critical components of the suspension system in-house in Knoxville, Tennessee.

That vertical integration gives Scott’s control over quality while allowing us to develop suspension systems for applications that don’t have an off-the-shelf solution.

Whether it’s a popular C10 or F100, an unusual classic vehicle or a completely custom application developed using 3D scanning, Scott’s has the equipment and experience to engineer a suspension solution around the vehicle.

From Daily Drivers to 1,000+ HP

Scott’s IFS isn’t limited to lightweight street rods or show vehicles. Our suspension systems are used beneath everything from comfortable daily-driven classics to 1,000+ horsepower performance builds.

Heavy-duty DOM control arms, substantial crossmember construction, modern steering, performance brakes and properly engineered suspension geometry provide a foundation designed for vehicles that are meant to actually be driven.

Scott’s IFS vs. Typical Mustang II-Style IFS

There Is a Difference in Independent Front Suspension

Not every aftermarket IFS is a Mustang II, and not every suspension system is engineered to the same standard. The components beneath your vehicle determine how it steers, handles, brakes and responds every mile you drive it, making the front suspension one of the most important systems in the entire build.

Scott’s Hotrods developed its proprietary Independent Front Suspension around the needs of modern hot rods, classic cars and custom trucks. From our massive DOM control arms and heavy-duty one-piece crossmember to adjustable coilovers, rack-and-pinion steering, anti-dive geometry and Grade 8 hardware, every component is designed to function as part of a complete suspension system.

Whether you’re upgrading an original frame with a Scott’s Weld-On or Bolt-On IFS or starting with a complete Built-To-Order Scott’s chassis, you’re getting the same philosophy we’ve applied to award-winning custom vehicles for decades:

Build it strong. Engineer it correctly. And build it to be driven.
