Fitment, Shipping & Product Support
The Apex Chassis ProLock Drag Link (KIT387-BLK) is a direct-replacement extreme-duty drag link for the 2014–2026 Ram 2500 and 2013–2026 Ram 3500 4WD SRW. 2" black anodized 7075-T6 aircraft-grade aluminum adjusting rod, SAE 1045 CNC-machined forged steel housings, SAE 4140 hot-forged induction heat-treated chromoly ball studs, ProLock™ machined keyway washers, jam nuts with 3 wrench-flat set screws, internal Flopper Stoppers (27° left/right, 2° front/back), reversible stainless steel taper sleeve for flip applications. Gas and 6.7L Cummins diesel. 2–6" lift range. Full front-end alignment required post-install.
Mechanically identical to KIT387-POL — same 2" 7075-T6 rod, same ProLock system, same 21 lbs. The only difference is finish. Drag link only — tie rod sold separately as KIT386-BLK. Complete master kit KIT385-BLK bundles both for one installation and one alignment fee. 2013 Ram 2500 does NOT fit. Ram 3500 DRW requires a different SKU.

Common Questions
What's the difference between KIT387-BLK and KIT387-POL?
Finish only. Same 2" 7075-T6 aluminum rod, same ProLock system, same Flopper Stoppers, same reversible taper sleeve, same 21 lbs. BLK is black anodized — zero maintenance, resists chips, heat cycles, and road salt. POL is raw mirror polished — show-quality finish that restores with aluminum polish over time.
Will this fix death wobble on my Ram 2500 or 3500 Cummins?
It eliminates the flex, joint slop, and adjusting sleeve rotation that heavily contribute to death wobble. The 2" 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.
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 the stabilizer mounting point. No fabrication required.
What does the minimum engagement mark mean?
A laser-etched safety reference line on the drag link threads. After adjusting the sleeve, this mark must remain hidden inside the sleeve. If it's visible, thread engagement is unsafe — redistribute the sleeve between the two ends, or the truck may need a flip kit.
I have a Carli high mount stabilizer on a 2016 Ram — what do I need?
Use the 2019+ Carli high mount regardless of your truck's model year. This applies to all 2014–2018 trucks.
The Obsidian Take
The KIT387-BLK is for the Ram HD owner who runs the truck hard and needs the steering to keep up without a maintenance schedule. Black anodized finish handles chips, heat cycles, and road salt without attention. The 2" 7075-T6 construction, Flopper Stoppers, Grade 8/Class 10.9 hardware, and ProLock adjustment retention are engineered for a Cummins diesel Ram 3500 pulling a gooseneck at GVW as much as a weekend trail truck.
If mirror finish matters more than zero maintenance, the mechanically identical KIT387-POL is the call. If maximum rigidity under extreme impact with zero flex memory is the priority, the KIT387-STL steel variant is the call. If your tie rod is also OEM, order KIT385-BLK and correct both in one session.
Confirm before ordering: 2013 Ram 2500 does not fit, Ram 3500 DRW requires a different SKU, and BDS trackbar and Rough Country dual stabilizer are hard incompatibilities.
Non-Returnable Notice: Steering components that have been installed are non-returnable. Confirm model year, SRW vs. DRW, trackbar and stabilizer configuration before ordering.
