Fitment, Shipping & Product Support
The Apex Chassis KIT186 is a direct-replacement extreme-duty tie rod assembly for the 2014–2024 Ram 2500 and 2013–2024 Ram 3500 4WD. Oversized tie rod ends connected by a massive DOM tube, ProLock machined keyway washers, jam nuts with set screws, Flopper Stoppers, and the TR203 OE location damper bracket included. Eliminates death wobble contribution and tightens up steering under the most extreme conditions. Gas and 6.7L Cummins diesel. Full front-end alignment required post-install.
This is the tie rod only. Drag link sold separately (KIT387 series). Complete steering kit KIT385 bundles both.

Common Questions
Is KIT186 still available or has it been replaced?
Apex Chassis's own product page designates KIT186 as superseded by KIT386. If you're sourcing new, confirm current availability and warranty support before ordering. Contact us before placing an order on this SKU.
What stabilizers are compatible with this tie rod?
Carli low mount stabilizers using Carli-provided brackets are confirmed compatible. Fox 2.0 in the OE location is compatible. High mount stabilizer systems, Fox TS and Fox ATS, and Rough Country dual stabilizer kits are not compatible with this SKU.
Does this fit a Ram 3500 Dually (DRW)?
Not confirmed in available sourcing. Every authorized source lists SRW without DRW-specific confirmation. Verify before ordering for a dually.
The TR203 damper bracket — what is it?
The TR203 is an OE-location steering damper bracket included with this kit. It allows the factory or replacement stabilizer to mount in the stock position on the tie rod assembly.
The Obsidian Take
The KIT186 is the predecessor to the current KIT386 series for the 2014+ Ram HD platform — same DOM tube tie rod upgrade with the TR203 OE location damper bracket included. If you're sourcing this from existing inventory, confirm its superseded status and warranty coverage before ordering. For new orders, the KIT386 series is the current Apex Chassis replacement for this application.
Don't stop at the tie rod. Pair with KIT387 drag link in your preferred finish for a complete front steering rebuild in one session.
Non-Returnable Notice: Steering components that have been installed are non-returnable. Confirm model year, SRW vs. DRW, stabilizer compatibility, and current product availability before ordering.
