What This Kit Actually Is
This is a 16" tender spring assembly with a 3-hole separator plate - it holds your service, emergency, and sometimes a third air line (or electrical cord) together in one bundle instead of letting them flop loose. The spring keeps tension so the hoses retract when you disconnect and don't drag under the trailer.
It mounts on the back of the cab or the tractor frame, wherever your air line bracket is set up. Pretty much a universal application across Class 8 tractors - Freightliner, Kenworth, Peterbilt, International, Volvo all run some version of this setup, since the hardware itself isn't OEM-brand specific.
Part number F01777S115 is the aftermarket piece number here, matched up to industry-common numbers like 17-148, 94162, and 451036 that you'll see floating around different catalogs.
Why The Numbers Cross
These separator/tender kits get relabeled a lot because the design is generic - a spring, a mounting bracket, and a plate with holes drilled for however many lines you're running. 17-148, 94162, 17-145, and 022023 all reference variations of the same basic 3-hole tender assembly, just packaged under different supplier numbers over the years.
Where you need to pay attention is hole count and spacing on the separator plate, and overall spring length. A 3-hole plate won't help you if you're only running two air lines plus no electrical cord, and a 16" spring might be too long or short depending on how your frame brackets are spaced. Measure your old unit end to end before you order.
If your old part has any stamped numbers left on it, that's your surest reference point. Rust and road grime eat those numbers fast on this kind of hardware, so if you can't read anything, pull the whole assembly and bring it in or send us a photo.
Ordering From PartStop

17-148 Cross-Reference & Interchange Numbers

Frequently asked questions
Does 17-148 fit my Kenworth T680?
Likely, since these tender kits aren't chassis-specific, but confirm hole count and spring length against your old unit or bracket spacing before ordering - T680s have had a couple different air line bracket configs over the years.
Is this the same as the 94162 crossed part?
Functionally yes, both reference the same 3-hole spring tender design, just different supplier catalog numbers. Physical dimensions should match but double-check your old part's measurements if you still have it.
How do I know if I need 2-hole or 3-hole?
Count your lines - service air, emergency air, and if you run a separate electrical cord through the same tender, that's your third hole. Most straight air-only setups just need 2-hole, but plenty of trailers route the 7-way through the same bundle.
