Fitment Disclaimer
Last Updated: April 14, 2026
At Obsidian Forged Auto Supply, fitment accuracy matters. We provide product data, fitment guidance, vehicle-specific notes, technical resources, and support to help customers choose the right parts for their build.
However, aftermarket fitment is not always simple. Vehicle year, trim, drivetrain, engine, axle configuration, suspension setup, wheel specs, tire size, factory packages, and previous modifications can all affect compatibility.
By purchasing from Obsidian Forged Auto Supply, you agree that you are responsible for verifying that the product is compatible with your specific vehicle before purchase, installation, and use.
1. Customer Fitment Verification Requirement
Before placing an order, you are responsible for confirming that the part matches your vehicle and build configuration.
This includes, but is not limited to:
| Fitment Factor | What To Verify |
|---|---|
| Year / Make / Model | Confirm the product supports your exact vehicle year, make, and model |
| Trim Level | Verify trim-specific differences such as Rubicon, Denali, AT4, Power Wagon, Raptor, Tremor, Trail Boss, ZR2, TRD Pro, or other packages |
| Engine | Confirm compatibility with gas, diesel, EcoDiesel, HEMI, Duramax, Power Stroke, EcoBoost, hybrid, or other engine variants |
| Drivetrain | Verify 2WD, 4WD, AWD, solid axle, IFS, and axle-specific requirements |
| Cab / Bed / Wheelbase | Confirm crew cab, extended cab, regular cab, short bed, long bed, and wheelbase restrictions |
| Existing Suspension | Account for current lift kits, leveling kits, aftermarket control arms, coilovers, shocks, springs, or spacers |
| Wheels & Tires | Verify wheel diameter, width, offset, backspacing, bolt pattern, tire size, and rubbing clearance |
| Brakes & Axles | Confirm clearance with factory or aftermarket brake packages, axle swaps, and high-capacity packages |
| Factory Packages | Review towing packages, off-road packages, payload packages, and special-edition configurations |
| Prior Modifications | Account for any previous changes that may affect fitment, geometry, clearance, or installation |
If any part of your build is modified, custom, swapped, lifted, leveled, or non-standard, do not assume catalog fitment automatically applies.
2. Fitment Data Sources
Fitment information on Obsidian Forged Auto Supply may come from:
| Source | Purpose |
|---|---|
| Manufacturer fitment data | Primary compatibility information supplied by the brand |
| Product documentation | Install notes, specifications, exclusions, and technical requirements |
| Supplier catalog data | SKU-level product classification and vehicle mapping |
| OFAS internal review | Additional page-level clarification, lockouts, buyer notes, and fitment warnings |
| Customer support review | Pre-purchase guidance based on the details you provide |
We make reasonable efforts to present accurate fitment information, but manufacturer data may change, contain exclusions, or fail to account for every vehicle variation.
3. Fitment Limitations
Fitment data may not account for every real-world vehicle condition.
Possible limitations include:
| Limitation | Why It Matters |
|---|---|
| Mid-year production changes | Vehicle manufacturers may change components during the same model year |
| Regional variants | Some trims, engines, or packages vary by market |
| Previous modifications | Prior lift kits, wheels, tires, bumpers, or suspension parts can change compatibility |
| Stacked upgrades | Multiple aftermarket parts may interfere with each other |
| Wear or damage | Bent brackets, worn bushings, sagging springs, or prior repairs can affect installation |
| Installer judgment | Some products require measurement, trimming, alignment, or adjustment during install |
Obsidian Forged Auto Supply is not responsible for fitment assumptions made without verifying the full vehicle configuration.
4. Aftermarket vs. OEM Parts
Unless a product is clearly labeled as Original Equipment, Genuine OEM, or direct factory replacement, products sold by Obsidian Forged Auto Supply should be treated as aftermarket components.
Terms such as:
| Term | Meaning |
|---|---|
| Compatible with | Designed to work with a listed vehicle configuration |
| Fits | Matches the manufacturer’s stated fitment range |
| Designed for | Built for a specific vehicle, platform, or use case |
| Replacement | Replaces a factory-style component unless otherwise stated |
| Universal | May require fabrication, measurement, wiring, trimming, brackets, or custom installation |
Aftermarket parts may change ride quality, handling, stance, clearance, alignment requirements, towing behavior, lighting performance, or service intervals.
5. Lifted & Modified Vehicle Complexity
Lifted, leveled, and modified vehicles require extra fitment review.
Suspension and wheel changes can affect:
| Area | Possible Effect |
|---|---|
| Caster | Steering return-to-center, tracking, and stability |
| Camber | Tire wear and alignment range |
| Toe | Steering feel, tire wear, and drivability |
| Scrub Radius | Steering effort, rubbing, and suspension feedback |
| Driveshaft Angles | Vibration, binding, and premature wear |
| Brake Line Length | Stretching or clearance issues |
| Shock Travel | Bottoming out, topping out, or reduced travel |
| Tire Clearance | Rubbing on fenders, control arms, bumpers, liners, or body mounts |
If your vehicle already has a lift kit, leveling kit, oversized tires, aftermarket wheels, upgraded brakes, axle swaps, or custom fabrication, contact support before ordering.
6. Professional Installation & Safety
Suspension, steering, braking, recovery, lighting, and electrical components can affect vehicle safety.
We strongly recommend professional installation by a qualified technician or experienced specialty shop, especially for:
| Product Category | Why It Matters |
|---|---|
| Suspension systems | Geometry, torque specs, alignment, and ride control |
| Steering components | Road safety, joint angles, torque, and steering response |
| Wheels and tires | Load rating, offset, rubbing, brake clearance, and hub fitment |
| Lighting and wiring | Circuit protection, fusing, relays, grounding, and waterproofing |
| Recovery equipment | Mounting strength, load ratings, and safe recovery use |
| Performance parts | Heat, clearance, tuning, emissions, and drivability concerns |
Improper installation may cause part failure, unsafe handling, electrical issues, vehicle damage, or voided warranty coverage.
Obsidian Forged Auto Supply is not responsible for damage, labor costs, vehicle failure, safety hazards, or denied warranty claims resulting from improper installation or incompatible parts.
