What You're Actually Buying
This is the insert screen that fits inside the front grille opening on a Kenworth T680 - it's the piece that keeps bugs and road debris out of the radiator core, not the grille shell itself. Kenworth ran a few different grille configurations on the T680 over the model years, so this screen is built to match the L45-6064-110 opening specifically.
Some shops call this a 'bug screen,' others just say 'grille screen' or 'insert' - same part, different counter lingo. It bolts or clips into the existing grille frame, so your shell and mounting hardware stay put. You're just swapping the screen itself.
Because Kenworth changed grille styling a couple times on the T680, this screen isn't a blind swap across every year. Pull the old part and check the number stamped or tagged on it before you order.
Why These Numbers Cross
L45-6064-110 is the Kenworth-side number, and it lines up with a handful of aftermarket and OE-reference numbers like KWN-017-3S26, 02-1210555, KWN-017, L29-6155-100, and RS-402-001-2. These all trace back to the same screen dimensions and mounting pattern - different manufacturers or catalog systems just tag it differently depending on who's cataloging it.
Where guys get burned is assuming any 'T680 grille screen' fits any T680. Frame width, mesh opening size, and the clip/bolt pattern all have to match your grille shell exactly, or it'll rattle, gap, or just not seat right. The number stamped on your old screen - or the VIN if the screen's long gone - is what actually confirms fit.
If you're working off a parts book cross-reference instead of the physical part, double check the tag on the grille shell too. Sometimes the shell number and the screen number get confused, and they're not interchangeable.

Frequently asked questions
Does L45-6064-110 fit my T680?
Depends on the model year and grille configuration - Kenworth changed the T680 grille a couple times. Check the number on your old screen or give us the VIN and we'll confirm before you order.
Is this the same as KWN-017-3S26?
They cross-reference to the same screen dimensions and mounting pattern, yes. Different catalog number, same physical part - but always match against what's actually on your truck before swapping.
Can I just buy a whole new grille shell instead of the screen?
You can, but if the shell's fine and it's just the screen that's torn or missing, no reason to spend the extra money. This part is just the insert - saves you from replacing the whole front grille.
