Front upper A-arm different across model years?

[jja]

For 07 KJ the part no. would be 52088632AC while for '06 KJ it'd be 52088632AD. Haven't really checked further back in model years.

I see a single factory length (i.e. for not lifted KJs) model at JeepinByAl. I really wonder what's the chance it turns out to be different size than the factory one I have. That'd really screw up alignment.

So far I was under the impression that all KJ's had the same upper control arm. Anybody encountered different flavors?

All 02 to 07s are the same, didn't change until 08 when the KK came out

The a-arms on JBA are universal for all KJ model years 02-07
They have a lifted set and a stock set, both have replaceable ball joints unlike the stock a-arms that come with the KJ

Whoops, didn't see Tom already replied.

Why the different part number then? I don't have that much experience with Jeep but with other manufacturers that means different part.

Could be a different ball joint or something, but the JBA ones will work and nothing is different about the geometry between 02-07.

...how about lower? I know kk knuckle is different and requires kk lca. Would those fit bolt on on kj?

Updated part,different supplier.

The #'s are the same besides the last digit meaning a updated part or different supplier,not a different part.
