What tube sizes are available?
Our most popular size is 3.5" diameter. However, we can build these axles with almost any diameter tubing you would like, including: 3.0", 3.125", 3.25", and 3.5".
What wall thickness of tubing does Diamond Axles use?
We use a lot of .375" wall tubing. However, we can use .25", .375", and .5". It depends on how heavy the vehicle is and other build requirements.
Whose knuckles do you use?
On Dana 60 outers we use Dedenbear inner and outer knuckles. On Dana 44s we use Crane, and on Toyotas we use original equipment.
Why Kingpin and no ball joint?
We exclusively use Kingpin knuckles for a number of reasons. First, a vast aftermarket support for these knuckles yields many different steering arm setups, allowing easy fit into a wide array of vehicles. Second, the Kingpin is a very strong steering pivot, as we have seen numerous ball joints broken on the trail. Lastly, Kingpins also have a very large bolt pattern to mount steering arms to, making the connection very strong.
What material is used in the axle shafts?
Some companies use stock material as a default. We use 4340 chrome-moly heat treated alloy steel. The cost difference is minimal while the strength different is large. It was a logical choice for us. However, we can also use 300M if requested.
What U-joints are used?
We use both forged Spicer units and CTM joints. CTM produces arguably the strongest joint made, produced from forged 300M. Sometimes this strength is not needed, and that where the Spicer units come in.
How are these units shipped?
We ship UPS for bare housings and unassembled axles, complete assemblies ship freight. We can ship to a variety of locations; from residential to a local terminal for the truck company. Obviously terminal shipping is the cheapest and residential is the most convenient. We'll be happy to give you a shipping quote for both so you can compare.
