Fitment, Shipping & Product Support
The Cognito Front Fender Liner Tie Back Kit (110-91193) resolves a clearance deficit on the 2020–2025 Silverado/Sierra 2500HD/3500HD: the factory front fender liner bracket positions the lower rear portion of the wheel well liner in a location that contacts larger tires and offset wheels before full suspension compression. This kit replaces the factory fender liner brackets with mild steel, semi-gloss black powder coated brackets that mount at the same OEM bolt locations but reposition the liner further rearward — creating the clearance margin required for larger tires and offset wheels at full compression. 30-minute DIY install using basic hand tools, no lift required. No trimming needed if factory mud guards are removed; trimming required per included instructions if mud guards are retained. Made in the USA. Limited lifetime warranty to the original retail purchaser for as long as they own the vehicle — excludes racing or competition use.

Common Questions
Do I need to trim anything to install this?
Only if you're keeping your factory mud guards — trim them per the included instruction sheet. If you remove the factory mud guards, no trimming is required.
How long does installation take?
About 30 minutes with basic hand tools. No lift is required.
Will this work at a lift height other than 3 inches?
The verified tire/wheel clearance combinations are specifically tested at 3" of level. Confirm clearance for your specific lift height before ordering if it differs.
What's the warranty?
Limited lifetime warranty to the original retail purchaser for as long as they own the vehicle the product was installed on. Does not cover racing, competition use, or installation contrary to Cognito's specifications.
Does this work with my Sierra AT4X or Denali Ultimate?
Yes, for 2024–2025 model years specifically — these trims were introduced partway through the platform's production run, so confirm your exact model year matches the trim-specific fitment.
The Obsidian Take
The 110-91193 is for the leveled or lifted 2020–2025 Silverado/Sierra 2500HD/3500HD owner who wants 35s or 37s without fender liner contact at full compression — a precise, bolt-on fix for a known clearance bottleneck, verified at 3" of level with specific tire/wheel/offset combinations rather than vague "fits bigger tires" marketing.
The honest checks before ordering: confirm whether you're keeping or removing your factory mud guards (trimming required only if keeping them), and confirm your lift height matches the 3" verification baseline if you're not running exactly that.
Non-Returnable Notice: Once installed, this product is non-returnable. Confirm mud guard retention plan and lift height before ordering.

One distributor listed an alternate zinc-plated finish inconsistent with the majority of sources confirming semi-gloss black powder coat — powder coat finish is used here as the predominant confirmed spec.
