Apex Chassis KIT185 Complete Steering Kit — 1.75" Heavy-Wall DOM Steel | E-Coat | 2014–2022 Ram 2500 / Ram 3500 4WD | Radius-Arm Platform | 0–6" Lift | Gas, 5.7L HEMI, 6.4L HEMI & 6.7L Cummins

Eliminate the flex. Lock the front end. Done.

Factory tie rod and drag link sleeves on the 2014–2022 Ram HD were engineered for narrow stock tires at stock height. When you lift it, add 35s or 37s, and place the immense weight of a 6.7L Cummins diesel block over the front axle, the factory linkage bows and flexes under the leverage — feeding the tracking instability, highway wander, and death wobble that makes a built Ram exhausting to drive.

The Apex Chassis KIT185 is the permanent engineering fix. A complete 1.75" heavy-wall DOM steel tie rod and drag link assembly with Ninja Washers locking system and E-coat protection — engineered specifically for the 2014–2022 Ram 2500 and Ram 3500 4WD radius-arm platform at 0–6" of lift. Gas or 6.7L Cummins diesel. Both components. One kit. Front end locked.

⚠️ Stabilizer clamp required: Your OEM stabilizer clamp will not fit the 1.75" DOM steel tie rod. Add Apex DC154 (standard/OEM stabilizer) or Apex DC151 (Fox stabilizer) to your order before checkout. Do not order without one.

Why DOM steel on the Ram HD radius-arm platform: The 2014–2022 Ram HD radius-arm geometry provides the correct clearance envelope for the 1.75" outer diameter on both bars. The DOM process eliminates the internal weld seam and produces uniform wall thickness throughout — delivering immediate structural resistance against bending under the immense leverage of a heavy 6.7L Cummins block over the front axle with wide aftermarket wheel offsets. Factory thin-walled stamped sleeves yield under these loads. This does not.

Why Ninja Washers over standard adjusting sleeves: Apex completely eliminates the thin factory adjusting sleeves and weak pinch clamps that slip out of alignment under strain. The Ninja Washers mechanical keyway system combined with dual-thread jam nuts physically locks your toe and drag link dimensions. It cannot back out or slip on the trail or under extreme towing stress.

Unsprung mass note: At 60.5 lbs this is a maximum-duty structural assembly. Performance-valved tracking shocks or an upgraded steering stabilizer setup are strongly recommended — stock shocks are not optimally valved for the added mass over harsh highway chatter.

✅ This kit fits — radius-arm solid front axle 4WD

❌ This kit does NOT fit — read before ordering

⚠️ Camber note — important for alignment shop: The 2014–2022 Ram 2500/3500 4WD runs an AAM 9.25 solid front axle where factory camber is entirely fixed and non-adjustable without aftermarket offset ball joints. Post-install alignment corrects toe and centers the steering wheel — camber remains fixed on this platform. Inform your alignment tech before the appointment.

⚠️ Stabilizer clamp — required additional hardware: Your factory stabilizer clamp is sized for the narrow OEM tie rod and will NOT seat on the 1.75" DOM tube. Add DC154 (standard OE-style stabilizers) or DC151 (Fox stabilizers) to your order. Text (469) 407-7538 with your stabilizer brand and we'll confirm the correct clamp before we ship.

⚠️ High-mount and dual stabilizer incompatibility: This kit is NOT compatible with high-mount steering stabilizer configurations. Aftermarket dual steering stabilizer brackets may require physical clearancing to clear the oversized rod end housings at full steering lock. Verify your setup before ordering.

Supporting mod requirements:

• 0–4" of lift: Direct bolt-on beyond the required stabilizer clamp.
• Lifts exceeding 4": Verify parallel tracking paths with your track bar. A track bar relocation bracket may be recommended.

Before You Buy — Questions We Get Asked

Q: Will this fix death wobble on my Ram 2500 or Ram 3500 Cummins?

Yes — provided ball joints and track bar bushings are in serviceable condition. Ram HD death wobble is triggered by a combination of loose tracking geometry and flexing factory linkage. The oversized 4140 chromoly ball studs, thick-walled 1.75" DOM steel tubing, and zero-play Ninja locking washers remove the compliance that permits the front-end tracking to oscillate out of control. For a complete fix, confirm ball joints and track bar are in good working order before installing.

Q: Can I run this on a completely stock-height truck?

Yes. The KIT185 is engineered to install at factory ride height all the way up to 6 inches of lift. At stock height, verify the drag link angle does not create bump steer before installation. At higher lift profiles, verify parallel tracking paths with your track bar.

Q: Why does this kit need a separate stabilizer clamp?

The factory stabilizer bracket is built for the narrow OEM tie rod diameter. The Apex 1.75" DOM steel tube is significantly larger — the factory clamp cannot seat correctly. Add Apex DC154 for standard OE-style stabilizers or DC151 for Fox stabilizers. Text us your stabilizer brand and we'll confirm the correct one before we ship.

Q: How hard is this install and what will I need?

Intermediate difficulty. Standard hand tools, a torque wrench, and a floor jack are required. A full front-end toe alignment immediately after is mandatory — do not drive at highway speeds until alignment is complete. The kit arrives pre-greased but features zerk fittings for ongoing field service. Budget one garage session for the swap and one same-day alignment appointment — and order your stabilizer clamp before installation day.

The Obsidian Take

The KIT185 is built for the Ram HD owner who lifted the truck, put real tires under it, and needs the factory compliance engineered out of the front steering track permanently. The 1.75" heavy-wall DOM construction with CNC-machined SAE 1045 forged steel housings and induction-hardened SAE 4140 ball studs eliminates the structural bending that triggers death wobble on Cummins and HEMI builds running heavy tire packages. The Ninja Washers physically lock alignment settings against trail vibration and sustained towing loads — not a marketing claim, a mechanical lock. The pre-greased construction with field-serviceable zerk fittings means this assembly is built to be maintained for the life of the truck. At 60.5 lbs it is a maximum-duty structural package — performance-valved shocks are strongly recommended to complement the added front axle mass.

This kit is not for 2013 or earlier Ram HD owners — the previous generation crossover steering uses completely different track widths and taper angles, see the KIT380 series. It is not for 2WD Ram HD owners. It is not for high-mount steering stabilizer setups — clearance binding will occur. If your aftermarket dual stabilizer bracket has tight clearances around the rod end housings, verify before ordering. And the factory stabilizer clamp will not seat on the 1.75" tube — add DC154 or DC151 to your order before you check out. Text (469) 407-7538 with your year, lift height, and stabilizer setup and we'll confirm everything before we ship.
