Apex Chassis KIT387-BLK ProLock Drag Link — 1.75" Black Powdercoat 7075-T6 Aluminum | 2014–2026 Ram 2500 / 2013–2026 Ram 3500 4WD | 2–6" Lift | Gas & 6.7L Cummins

Built for a truck that doesn't stop.

A lifted Ram HD that earns its keep doesn't get babied. It hauls. It tows. It runs loaded on the highway Monday through Friday and gets pushed hard on weekends. Your OEM drag link was engineered for stock ride height — lift that same truck 2–6 inches and the geometry breaks. The link angle works against your front axle instead of with it, introducing the bump steer, the wander, and the constant correction that turns a working truck into a handful.

The Apex Chassis KIT387-BLK is the correction. A 1.75" solid 7075-T6 aircraft-grade aluminum drag link with black powdercoat finish, ProLock high-misalignment joints, internal Flopper Stoppers, and a reversible stainless steel taper sleeve — built specifically for the 2014–2026 Ram 2500 and 2013–2026 Ram 3500 4WD platform at 2–6" of lift. Gas and 6.7L Cummins diesel. Designed for a truck that doesn't stop.

Section 1 — Comprehensive Sizing Matrix

Why 1.75" and not 2": The Ram front axle layout around the track bar drop bracket and differential housing has significantly tighter clearance tolerances during full steering lock cycles than the Ford platform. A 2" bar binds on a standard 2014+ Ram 2500/3500. The 1.75" spec is the correct diameter for this platform's geometry — 7075-T6 delivers full structural rigidity to eliminate death wobble contribution while retaining flex memory to absorb direct impacts without bending flat like mild steel.

The reversible taper sleeve: On high-lift Ram setups, installers frequently perform a drag link flip at the pitman arm to correct geometry. A standard flip makes mounting a steering stabilizer impossible because the tapered hole points the wrong direction. The KIT387-BLK comes with a straight-bored stabilizer hole and a reversible stainless steel taper sleeve — flip the link geometry at the pitman arm and the stabilizer mounts cleanly from either face without fabrication.

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

❌ This unit does NOT fit — read before ordering

2013 year-split — critical: Ram updated the Ram 3500 to the radius-arm front suspension in 2013 — a full model year before the Ram 2500. This unit fits the 2013 Ram 3500 but will NOT fit a 2013 Ram 2500. If you have a 2013 Ram 2500, contact us for the correct unit.

⚠️ Ram 3500 DRW owners: This unit fits Ram 3500 SRW only. If your Ram 3500 is a dually, text (469) 407-7538 before ordering — a different SKU may be required.

⚠️ Rough Country Dual Stabilizer incompatibility: The KIT387-BLK is NOT compatible with Rough Country dual steering stabilizer kits due to component interference with the drag link rod ends. Generic dual stabilizer brackets from other brands may require minor clearance modification — text us your setup before ordering.

⚠️ Minimum Engagement Mark: This unit features a laser-etched minimum thread engagement mark. If this line is exposed during adjustment, your lift geometry exceeds the standard link range and requires a dedicated steering flip setup. Contact us before ordering if your lift exceeds 6".

Supporting mod requirements:

• Lifts 2–4": Direct replacement. No additional hardware required beyond the unit.
• Lifts exceeding 4": Track bar relocation bracket strongly recommended. Verify pitman arm drop compatibility before ordering.

Before You Buy — Questions We Get Asked

Q: What's the difference between KIT387-BLK and KIT387-POL?

Mechanically identical — same 1.75" 7075-T6 aluminum rod, same ProLock system, same Flopper Stoppers, same reversible taper sleeve, same 21 lbs. The only difference is finish. The BLK is industrial black powdercoat — completely maintenance-free, resistant to chips, heat cycles, and road salt. The POL is raw mirror-polished aluminum — show-quality finish that occasional polish maintains over time. Same performance. Choose based on your build and use case.

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

It eliminates the flex, joint slop, and adjusting sleeve rotation that heavily contribute to death wobble. The 1.75" 7075-T6 rod, ProLock system, and internal Flopper Stoppers remove the slop that allows wobble to develop. When paired with healthy ball joints, a solid track bar, and a proper alignment, it completely tightens up the front track. If your tie rod is also OEM, the KIT385-BLK complete kit addresses both ends in one session with one alignment fee.

Q: Can I flip this drag link on a high-clearance lift setup?

Yes. The straight-bored stabilizer hole and included reversible stainless steel taper sleeve allow you to flip the link geometry at the pitman arm without losing your steering stabilizer mounting point. No custom fabrication required. Most builders don't encounter this problem until they're already mid-install — the taper sleeve solves it before you need it.

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 alignment — toe, caster, and tracking — immediately after installation is mandatory. Ensure joints are centered vertically during torque-down to engage the Flopper Stoppers correctly. Budget one garage session for the swap and one same-day alignment appointment.

The Obsidian Take

The KIT387-BLK is built for the Ram HD owner who runs the truck hard and needs the steering to keep up without a maintenance schedule. A Cummins diesel Ram 3500 pulling a gooseneck at GVW puts a fundamentally different load on a drag link than a weekend trail truck — the 1.75" 7075-T6 construction, Grade 8/Class 10.9 hardware, and ProLock system are engineered for exactly that application. The black powdercoat handles chips, heat cycles, road salt, and the environmental abuse that comes with a truck that earns its miles. The Flopper Stoppers build the anti-roll restriction directly into the forged steel housing — no external rubber blocks to wear out or lose on the trail. The reversible taper sleeve solves the drag link flip stabilizer mounting problem before you encounter it. One alignment appointment and the wander and death wobble contribution are resolved.

This unit is not for 2013 Ram 2500 owners — the radius-arm suspension update came one year later on the 2500 than the 3500 and this unit will not fit your geometry. It is not for Ram 3500 dually owners — text us and we'll confirm the correct SKU. It is not for builders running a Rough Country dual stabilizer — that combination has a hard interference conflict. If the mirror finish matters more than zero maintenance, the mechanically identical KIT387-POL in polished aluminum is the right call. And if your tie rod is also OEM, the KIT385-BLK complete master kit is the smarter purchase — both components corrected in one session with one alignment fee.
