Common Questions
Do I need the standard kit or the pitman arm bundle for my 2003–2008 truck?
If you already have the 2009–2013 pitman arm installed, order KIT380-POL. If you do not, order KIT380P-POL which includes the Mopar pitman arm for the Y-to-T conversion. If running a drop pitman arm, replace it with the 2009–2013 style from your lift supplier first.
What's the difference between KIT380-POL and KIT380-BLK?
Mechanically identical — same 2" 7075-T6 bars, same ProLock system. POL is raw mirror polished — show-quality finish that restores with aluminum polish. BLK is black anodized — zero maintenance, better corrosion protection for road salt environments. Same performance.
Will this fit a 2013 Ram 3500?
Only if it's early production T-style. Late 2013 Ram 3500 uses crossover steering and this kit does not fit. Look under the truck to confirm before ordering.
Does camber adjustment happen at the same time as alignment?
Camber is fixed on this solid front axle platform — it cannot be adjusted without aftermarket offset ball joints. Post-install alignment corrects toe and centers the steering wheel. Camber remains as-built by the axle.
Why won't my factory stabilizer clamp fit?
The factory clamp is sized for the narrow OEM tie rod. The Apex 2" aluminum tube requires a 2" ID clamp. Order DC2.0-B (black) or DC2.0-Z (zinc) separately, or text (469) 407-7538 with your stabilizer brand and we'll confirm the right clamp.
The Obsidian Take
The KIT380-POL is for the 3rd-gen Ram HD owner who lifted their truck, put real tires under it, and wants both the steering locked down permanently and a mirror-finish undercarriage to show for it. 2" solid 7075-T6 on both bars, ProLock adjustment, greaseable spherical bushing, natural flex memory that handles trail impacts without permanent deformation.
For a working truck in road salt conditions, the mechanically identical KIT380-BLK is the zero-maintenance call. For maximum rigidity under direct rock contact, KIT380-STL in DOM steel is correct. For 2003–2008 Y-style trucks, confirm whether you need KIT380P-POL with the Mopar pitman arm. For 2014+ Ram HD, stop here and order KIT385-POL.
Non-Returnable Notice: Steering components that have been installed are non-returnable. Confirm steering style (T-style vs. crossover), pitman arm status, stabilizer clamp size, and model year before ordering.
