ICON Vehicle Dynamics 1.75" Carrier Bearing Drop Kit for 2014-2026 Ram 2500

The ICON Vehicle Dynamics 1.75" Carrier Bearing Drop Kit is a CNC-machined aluminum spacer system designed for 2014–2026 Ram 2500 trucks running a 4.5" lift, lowering the rear driveshaft carrier bearing 1.75" from its factory position to restore proper driveline geometry after lifting.

Correcting Driveline Angles After a 4.5" Lift

Raising a Ram 2500 by 4.5" changes the angle at which the rear driveshaft operates. When the carrier bearing stays at its factory height, the resulting misalignment creates out-of-phase driveshaft conditions that produce vibration at speed. Dropping the carrier bearing 1.75" brings the driveshaft back into a geometry range that reduces those operating angles, smoothing out vibration that would otherwise persist regardless of how well the lift itself is installed.

Machined Aluminum Construction

The spacers are precision CNC machined from 6061 aluminum, a grade chosen for its combination of strength, low weight, and corrosion resistance. A component that lives under the truck and sees road debris, moisture, and temperature cycling depends on both dimensional accuracy and material quality to hold the correction long-term without introducing new problems.

Features

• 1.75" carrier bearing drop: lowers the rear driveshaft carrier bearing from the factory position for use with 4.5" lift systems
• Vibration reduction: corrects out-of-phase driveshaft angles that cause rear driveline vibration after lifting
• CNC-machined 6061 aluminum: precision construction with corrosion resistance and lightweight durability
• Hardware included: all necessary mounting hardware is included for installation

Who This Is For and Isn't

This kit suits owners of 2014–2026 Ram 2500 trucks that have been lifted 4.5" and are experiencing rear driveline vibration caused by the carrier bearing remaining at its factory height.

This kit is engineered for a 4.5" lift only and is not designed for Ram 2500 trucks running other lift heights. Ram 3500 fitment is not confirmed in the product application notes; see Review Flags.

Common Questions

What lift height is this carrier bearing drop kit designed for?

The ICON 1.75" Carrier Bearing Drop Kit is engineered specifically for 2014–2026 Ram 2500 trucks running a 4.5" lift. The 1.75" drop amount is sized to correct the driveline geometry that results from that specific lift height; it is not a universal fit for other lift amounts.

Does this kit include the hardware needed for installation?

Yes. The ICON Carrier Bearing Drop Kit includes all necessary mounting hardware. An installation guide is also available from ICON Vehicle Dynamics for reference during the install process.

Why does a lifted truck need a carrier bearing drop?

When a Ram 2500 is lifted 4.5", the rear driveshaft operates at a steeper angle while the carrier bearing remains at its factory height. That mismatch puts the driveshaft out of phase, which causes vibration at speed. Lowering the carrier bearing 1.75" restores the geometry needed for smooth driveshaft operation.

What material are the spacers made from?

The carrier bearing spacers in this kit are precision CNC machined from 6061 aluminum, providing corrosion resistance and light weight for a component that is exposed to the elements under the truck.
