Common Questions
Is KIT185 still available or has it been replaced?
Apex Chassis's own product page designates KIT185 as superseded by KIT385. Confirm current availability and warranty support before ordering.
Why won't my factory stabilizer clamp fit?
The factory clamp is sized for the narrow OEM tie rod. The Apex 2.125" DOM tie rod requires a larger aftermarket clamp. Order Apex DC154 for standard OE-style stabilizers or DC151 for Fox stabilizers.
Does camber get adjusted during alignment?
No. The 2014+ Ram 2500/3500 4WD runs a solid front axle where camber is fixed. Inform your alignment tech before the appointment — they will correct toe and center the steering wheel only.
Will this work on a stock-height truck?
Yes. The lift range starts at 0" — this kit installs at factory ride height through 6" of lift.
The Obsidian Take
The KIT185 is the predecessor to the current KIT385 for the 2014+ Ram HD platform — a complete DOM steel steering kit with TR203 damper bracket, Flopper Stoppers, and Ninja Lock Washer adjustment. If you're sourcing this from existing inventory, confirm the superseded status and warranty coverage before ordering. For new orders, the KIT385 series is the current Apex Chassis replacement.
Do not order without the correct stabilizer clamp. The factory clamp will not fit the 2.125" tie rod — add DC154 or DC151 to the order before checkout.
Non-Returnable Notice: Steering components that have been installed are non-returnable. Confirm model year, stabilizer clamp size, trackbar compatibility, and current product availability before ordering.
