Why Scott’s Hotrods SuperSlam Independent Front Suspension Crushes the Competition

Scott’s Hotrods Independent Front Suspension is the real deal—not a Mustang II knockoff. Every IFS kit we make is a true, vehicle-specific front suspension, engineered from the ground up with tubular upper and lower A-arms designed for your exact ride.

Forget flimsy 3-piece crossmembers with spring pocket hats and/or T-bolt sliders that loosen under stress. Scott’s IFS uses coilovers or airbags with external shocks, giving you precision handling you can dial in perfectly—and it stays aligned, no matter how hard you push it.

Every kit is 100% TIG-welded and built with 5/8” or larger Grade 8 hardware. That means strength, rigidity, and performance you can see and feel.

Don’t settle for imitation. Upgrade to Scott’s Hotrods IFS and drive a suspension that’s as badass as your ride.

Scott’s Hotrods SuperSlam Weld-On Airbag IFS

Scott’s Hotrods ‘n Customs SuperSlam Weld-On Airbag IFS is a true vehicle-specific Independent Front Suspension engineered for builders who want modern handling, adjustable ride height and the ability to get their hot rod, classic car or custom truck seriously low. Introduced more than 20 years ago, the SuperSlam helped set the standard for purpose-built airbag front suspension and has continued to evolve with stronger components, improved adjustability and proven suspension geometry.

Unlike universal airbag suspension kits or modified Mustang II-style systems, every Scott’s SuperSlam IFS is Built-to-Order for the specific vehicle application. Each kit combines Slam Specialties SS-6 airbags with RideTech HQ single-adjustable shocks, heavy-duty tubular A-arms and Scott’s massive one-piece TIG-welded crossmember. The result is an air ride front suspension designed to deliver the stance you want without sacrificing the strength, alignment control and handling your build demands.

Whether you’re building a slammed cruiser, high-end show car, Pro Touring build or custom truck designed to lay frame, Scott’s SuperSlam Airbag IFS gives you the adjustability of air suspension backed by more than two decades of real-world development.
