19 kx450 foot pegs ?

Don’t buy 16-18 OE pegs even if they fit. They pack with dirt so bad if it’s remotely sticky and you basically end up standing on blocks of mud. I actually prefer the 19 oe design to 18. Call one of the companies like raptor, they’ll be able to tell you. Or pro peg. Cross reference part #’s on works connection for 19 pro peg Ti peg see if it’s the same part as an 18. That’ll answer your question

I’ll trade you a set of brand new OEM 16-18 pegs for your used 19’s if that’s what you want. But yes they fit.

Yes the pegs fit, I had my works connection ultralight pegs from my 16 on my 19. I honestly like the stock 19 peg more though - they dull pretty quickly though.

Also, I HIGHLY doubt you're going to break a stock peg, man. You'll blow your leg apart before you shear a steel peg off
