One thing to watch out for is what you get for your money, some quote the whole kit including carrier, bearings, needle bearings,brakelines,etc and some are for the swingarm itself. From memory my new T-dub 660 swingarm not painted was about $290.00, its all the hardware that adds up.

The 06 Raptor 700 and YFZ are round housings from the factory, so you reuse your bearing carrier.

Ace is building me a swingarm for $550. This includes 4130 TIG construction, +4" length, skid plate mounts, and powder coating.

I sourced a brake line on Ebay for $26.

 

i have a brand new(never used) bare metal T-Dub +4(with maltese cross), With brand new carrier, and brand new pivot bearing, none have been install still in the box. Make me a offer.
