Drivetrain & 4WD Components

Axle and driveline parts for heavy-duty builds, mostly from Artec Industries, with additional items from Ekstrom Design, CMM Offroad and Clayton Off Road. Expect diff covers, axle trusses, 1-ton swap brackets, gussets and carrier bearing drop kits, largely for Jeep Wrangler TJ, JK and JL. Confirm axle model, such as Dana 44 or Ford 8.8, before you buy.

What's in Drivetrain & 4WD Components

This collection is axle and driveline hardware for heavy-duty builds. Artec Industries supplies the largest share, with items from Teraflex, Clayton Off Road, Ekstrom Design and CMM Offroad. By type it breaks down into axle reinforcements, complete axle sets and components, brake lines, transmission crossmembers and diff covers.

Most Jeep listings are for the Wrangler TJ, JK and JL and the Gladiator. There are also ICON brake line kits and carrier bearing drop kits for Super Duty, Ram HD and Land Cruiser.

How to choose drivetrain parts

Start with the axle. Identify what is under your vehicle, such as a Dana 44 or Ford 8.8, and match it exactly. Parts for a different axle, or for a different casting of the same axle, will not fit.

Then confirm:

  • Model year and generation. TJ, LJ, JK, JL and JT parts rarely cross over.
  • Front or rear axle, and whether you run the stock or a swapped axle.
  • Lift height for brake lines, carrier bearings and driveshaft changes. Extended lines and drop kits are sized to a range.
  • Whether the item is a bolt-on or needs welding.

Common companions are axle reinforcements, diff covers, brake lines and crossmembers. Lifting a vehicle changes driveline angles, so look at the related lift kit choices too.

Drivetrain & 4WD Components FAQs

What does an axle truss do?

An axle truss reinforces the axle tube, helping it resist bending under load or trail impacts. It is often paired with a heavier-duty axle build. Check that the truss matches your axle model and that your suspension setup leaves room for it.

How do I know which Dana 44 or Ford 8.8 parts I need?

Confirm the axle model and then the vehicle year, since axle housings have different variants. Axle details are in the listing title or description. If you cannot identify it, call (920) 249-7744 before you order.

What is a 1-ton swap bracket kit for a Wrangler TJ?

It lets you mount a different axle in place of the stock axle, using brackets that fit the Jeep's frame and suspension. Titles here name the axle casting and the Jeep years. Read the compatibility notes closely, since these are specialty parts.

Do I need a carrier bearing drop kit with a lift?

On some lifted trucks, yes. Lifting changes driveshaft angle, and a drop kit lowers the carrier bearing to restore it. The ICON kits here are listed by vehicle and lift height.

Are these parts for Jeeps only?

Most are for Jeeps, especially the Wrangler TJ, JK and JL. There are also parts for Super Duty, Ram, Tundra and Land Cruiser. Use the vehicle selector to narrow the list.
