If you’ve got an 1980–1996 Ford Bronco and you’re chasing better trail manners, strength, and suspension performance than the stock TTB setup can comfortably deliver, a Solid Axle Swap (SAS) is one of the most proven paths forward.

One of the most popular axle choices for a Bronco SAS is the High-Pinion (HP) Dana 44—a solid blend of availability, strength, and driveline-friendly geometry for a front axle in a 4x4.

Below is a practical overview of what an HP Dana 44 SAS involves, why people do it, and which ProtoFab parts can make the conversion cleaner and more reliable.

Why swap to a solid axle on an 80–96 Bronco?

Ford’s TTB (Twin Traction Beam) front suspension can work well, but it has limits—especially once you start adding lift, larger tires, and harder trail use.

A properly set up SAS can deliver:

• More predictable articulation off-road

• Simpler alignment and geometry compared to heavily modified TTB setups

• Better durability for aggressive trail driving

• More aftermarket support for suspension tuning and steering solutions

Why an HP Dana 44 is a common Bronco SAS axle

The HP Dana 44 is a favorite because it hits a sweet spot:

• High-pinion design improves front driveline angles (especially helpful with lift)

• Strong enough for many Bronco builds when geared and maintained properly

• Parts availability is generally good (gears, lockers, rebuild components)

It’s not the only option, but it’s a very common “right-sized” axle for Broncos that see real trail time without going full 1-ton in every area.

The big pieces of an SAS (what you’re really signing up for)

A solid axle swap isn’t just “bolt in an axle.” It’s a system change. The main areas you’ll plan around are:

1) Suspension mounting & geometry

You’ll need a way to locate the axle and manage travel. Most SAS builds use one of these approaches:

• Radius arms (common on Broncos)

• 3-link / 4-link (more complex, highly tunable)

You’ll also need:

• Coil buckets or coil-over mounts

• Track bar mount(s)

• Shock mounts

• Correct caster/pinion angle setup

2) Steering

Steering is one of the most overlooked parts of an SAS—and one of the most important.

You’ll need to solve for:

• Proper drag link and track bar relationship (to reduce bump steer)

• Strong tie rod/drag link components

• Clearance at full stuff/droop

• Reliable steering feel on-road

3) Driveline & gearing

Expect to evaluate:

• Front driveshaft length and angles

• Gear ratio matching front/rear

• Lockers (optional, but common)

4) Brakes, wheels, and fitment

Depending on your axle and knuckle setup, you may need:

• Brake upgrades or line changes

• Wheel backspacing adjustments

• Tire clearance planning

ProtoFab parts that make an HP Dana 44 SAS easier

ProtoFab builds parts for Broncos the way they’re meant to be used: tested in harsh Arizona conditions and designed for real-world trail reliability.

ProtoFab SAS Kit (Solid Axle Swap Kit)

If you’re doing an SAS, having the right brackets and mounting points can save you a ton of time—and help you avoid geometry mistakes that create handling issues later.

ProtoFab’s SAS Kit is a helpful product to make the conversion easier by giving you purpose-built components designed specifically for solid axle swap fabrication on classic Broncos.

Will ProtoFab’s SAS Kit work with a Dana 60?

Yes—ProtoFab’s SAS Kit can also be used on a Dana 60 as long as you’re set up to do the required welding and axle prep.

The key is that you’ll need to weld on the wedges from the HP Dana 44 and install the coil buckets as part of the swap so the suspension mounting points match the SAS setup.

In other words: if you’re stepping up to a Dana 60 for more strength, you’re not automatically “locked out” of the SAS Kit—just plan on the fabrication steps that make the axle compatible.

ProtoFab Chevy 1-Ton Steering Conversion

Once you’ve got a solid axle under the truck, steering becomes mission-critical—especially if you’re stepping up tire size or trail difficulty.

ProtoFab’s Chevy 1-Ton Steering Conversion is a great product for steering in the solid axle swap process because it’s designed to provide a stronger, more confidence-inspiring steering setup than many stock-style solutions.

It’s a popular direction for SAS builds because it supports the kind of durability and trail serviceability that Bronco owners actually need.

Quick planning tips before you start cutting

A few practical reminders that can save you headaches:

• Decide your lift height and tire size first. It affects everything: steering angles, shock length, driveshaft needs, and bump stop placement.

• Mock up steering and track bar early. Don’t leave it until the end.

• Measure twice, weld once. Bracket placement and axle centering matter.

• Plan for real-world use. If the Bronco sees highway miles, geometry and steering feel are just as important as flex.

Final thoughts

An HP Dana 44 solid axle swap can transform how an 80–96 Bronco drives off-road—and if it’s built correctly, it can still be comfortable and predictable on the street.

If you want to take the guesswork out of the fabrication side and build with parts designed for Broncos that actually get used, ProtoFab’s SAS Kit and Chevy 1-Ton Steering Conversion are two smart additions to your SAS plan.
