What This Frame Is and Where It Fits
The bug screen frame sits between the grille shell and the actual mesh screen on a T680. It's not the screen itself - it's the structural piece that clamps around it and bolts to the grille assembly. Kenworth ran this same frame design across the whole T680 production run from 2014 up through the 2023 facelift, so one part number covers a lot of trucks.
Where guys get tripped up is thinking every T680 grille setup is identical. Kenworth made minor running changes to the mounting tabs and screen retention clips over the years, and some fleet-spec trucks used a different bug screen altogether. Before you order, pull the number off your old frame or check the build sheet against your VIN - don't just go by model year alone.
Why These Cross Numbers Match Up
L45-6064-100 is the Kenworth number, but this frame also interchanges with L29-6155-100 and the aftermarket-coded numbers like KWN-017-2S26 and TRKWN017-2S26 - those are just different suppliers stamping their own part number on the same design. 185-6089REVB and 21274AA show up from other aftermarket manufacturers who reverse-engineered the OE frame dimensions.
All of these cross because the mounting hole pattern, frame width, and tab spacing match the factory Kenworth spec close enough to bolt up the same way. That said, 'close enough' on paper doesn't mean identical in your hands - powder coat thickness, tab stiffness, and mesh gauge can vary slightly between manufacturers even when the part number crosses clean. If your grille has been in a shop before, or the truck's had frame damage repaired, check that your bolt pattern still matches stock before assuming any of these will drop right in.

Frequently asked questions
Does L45-6064-100 fit my 2016 T680?
Likely yes - Kenworth used this frame design across 2014-2023 T680s - but confirm with your VIN or by checking the number stamped on your current frame before ordering. Some fleet-spec trucks ran different screen setups.
Is this the same as the KWN-017-2S26 part?
They cross-reference to the same frame dimensions and mounting pattern, so functionally yes, but they're made by different manufacturers. Fit should be equivalent but finish and material thickness can differ slightly - not a problem for most trucks, just worth knowing.
My old frame doesn't have a number stamped on it - now what?
Give us your VIN and we can look up what should've come on the truck from the factory. If the truck's had prior grille work done, that's not always reliable either, so worst case we walk you through measuring the mounting tabs before you order.
