What You're Actually Buying
This is a standard duty air brake shoe kit built to the 4707 size, which is one of the most common shoe platforms Kenworth used on T660 trucks running Meritor or similar cam-style foundation brakes. Kit includes shoes with lining already riveted or bonded on, plus the hardware you need to do the job right.
4707 isn't a brand name, it's an industry size/spec number. Every major reman and aftermarket shoe maker builds to that same 4707 footprint, which is why you see it followed by a letter suffix depending on lining grade and who boxed it.
Why All Those Numbers Cross
4707Q and GG4707QG are the same base 4707 shoe with a specific lining compound and grade stamped on. The 148.4707Q.20 and 20014707QP numbers are just other suppliers' catalog codes for that identical shoe size - different box, same shoe. 3528902 and 4707-Q-NB225 show up because different manufacturers and buying groups slap their own part number on the same casting.
Where guys get burned is drum diameter and cam roller/anchor pin spacing - 4707 covers a specific size range, but Kenworth ran a few different brake sizes across T660 spec'd axles depending on GVW and front vs rear application. Shoe curvature, lining width, and the anchor/roller pin holes all have to line up or the shoe won't seat right even if the box says '4707.'
Always pull the number off your old shoe before you order. If it's rusted over or worn off, check the tag on the brake spider or give us your VIN - we can look up what Kenworth spec'd for that T660 and confirm before it ships.

4707 Cross-Reference & Interchange Numbers
These manufacturer and aftermarket numbers commonly cross-reference to 4707. Use them to identify the part — then confirm the exact fit by VIN or the number stamped on your old unit before you order. An interchange is a starting point, not a fitment guarantee.

Frequently asked questions
Does 4707 fit my 2016 Kenworth T660?
Likely yes if your truck came with the standard cam brake setup, but Kenworth offered a few brake package options over the T660's run. Surest way to know for sure is match the number off your current shoe or give us the VIN and we'll confirm before you order.
Is GG4707QG the same as the plain 4707Q kit?
Same shoe size and hole pattern, yes - GG4707QG is just another manufacturer's stamping on the identical 4707 platform with a comparable lining grade. Functionally they interchange, but if you're picky about lining compound match, tell us what's currently on the truck.
Do I need new hardware kits with these shoes, or just the shoes themselves?
This listing is the shoe kit with hardware included, but if your rollers, bushings, or return springs are shot or grooved, replace those separately - reusing worn hardware is the number-one reason a fresh shoe install still comes back squawking.
