What vehicles have solid axles?
Solid axles are a type of vehicle suspension system where the left and right wheels are connected by a single, rigid axle. This design is commonly found in older vehicles, as well as in some modern off-road and heavy-duty applications. Solid axles provide increased durability and load-bearing capacity, making them a popular choice for trucks, SUVs, and other vehicles that need to handle rugged terrain or heavy payloads.
What is a Solid Axle?
A solid axle is a single, rigid component that connects the left and right wheels of a vehicle. Unlike independent suspension systems, where each wheel is connected to the vehicle frame by its own suspension components, a solid axle links the two wheels together. This design provides several benefits, including:
- Increased Strength and Durability: The solid, one-piece construction of a solid axle is inherently stronger and more durable than the multiple components found in independent suspension systems. This makes solid axles well-suited for heavy-duty applications.
- Improved Load Capacity: The rigid design of a solid axle allows it to support heavier loads without compromising stability or handling.
- Simpler Design: Solid axles have a relatively simple design, with fewer moving parts, which can make them easier and less expensive to manufacture and maintain.
However, solid axles also have some drawbacks, such as a rougher ride quality and reduced wheel articulation, which can impact off-road performance and handling on paved roads.
Vehicles with Solid Axles
Solid axles are commonly found in the following types of vehicles:
- Trucks and SUVs: Many pickup trucks, large SUVs, and other heavy-duty vehicles use solid axles, particularly on the rear axle, to handle heavy payloads and towing requirements. Examples include the Ford F-150, Chevrolet Silverado, and Jeep Wrangler.
- Off-Road Vehicles: Vehicles designed for off-road use, such as Jeeps, Land Rovers, and some military vehicles, often feature solid axles to provide increased ground clearance, articulation, and durability on rough terrain.
- Commercial and Agricultural Vehicles: Larger commercial trucks, buses, and agricultural equipment, such as tractors and combines, commonly use solid axles to handle heavy loads and operate in demanding environments.
While solid axles were once ubiquitous in many vehicle types, the rise of independent suspension systems has led to a decline in their use, particularly in passenger cars and smaller SUVs. However, solid axles remain a popular choice for vehicles that prioritize strength, durability, and off-road capability over ride quality and handling on paved roads.
What Toyotas had solid axles?
Toyota used a solid front axle in the '79-'85 pickups and 4Runners. All of these axles were 55.5 inches wide from wheel mounting surface (WMS) to wheel mounting surface and came with solid front disc brakes and closed knuckles with Birfields.
What SUVs have a solid front axle?
The only common 4x4s left offering a solid front axle in 2023 are the Jeep Wrangler, Ford Super Duty, and Ram HD trucks. Everything else, from Ford Broncos to Toyota Tacomas and 4Runners, uses independent front suspension.
What are the disadvantages of a solid axle?
However, solid axles have their drawbacks. They add weight to the vehicle and reduce efficiency. Ground clearance suffers as the differential hangs lower than with independent suspension.
Are jeeps still solid axle?
They are also reliable, easy to maintain, cheap to manufacture, and easier to modify. Yet Jeep is practically the only automaker left selling SUVs from the factory with a solid front axle. Most modern pickup trucks also come with independent front suspension.
What SUVS have a solid front axle?
The only common 4x4s left offering a solid front axle in 2023 are the Jeep Wrangler, Ford Super Duty, and Ram HD trucks. Everything else, from Ford Broncos to Toyota Tacomas and 4Runners, uses independent front suspension.
Do Mustangs have a solid rear axle?
Mustangs made from 1964.5 to 2014 use a solid rear axle set-up. The notable exceptions are the SVT Cobra models from 1999-2004, which used an independent rear suspension. These rare performance models are tough to find (and some have even been converted to solid axles).
What 4x4 has solid axles?
This setup is becoming used less often in new vehicles; however, there are still some models that use this kind of suspension. The Jeep Wrangler JK is one of the only Jeep models that still use a solid front axle. It is joined by Ram's heavy-duty range and Ford's Super Duty trucks, which also run with a solid axle.
Which vehicles have solid axles?

What is the benefit of a solid axle?
Solid axle setups have room for increased wheel travel, which is great if you're looking to add larger tires to your rig.
Do Fords have solid front axles?
You Bet! Q:Your answer to this question will settle a bet: My friend says that four-wheel-drive F-250s and F-350s always had solid axles up front. I say that from 1980-1985, all 4WD F-Series had TTB up front. Half-tons had trailing arms and coils, while 3/4- and 1-tons had leafs with TTB.
