NC Tom Posted February 15 Share Posted February 15 I ordered some SKP brand lower control arms for my 88 from rockauto and they are too wide by about +/- 1/2". They are supposed to be compatible. Does anyone know of a brand that are guaranteed to fit like OEM? Doesn't seem like anyone posts those technical measurements. They only post length. I'm not interested in the WJ mod and swap.

ratrapp Posted February 15 Share Posted February 15 (edited) do they actually measure 1/2 inch wider than your originals?ive had some that i trimmed a little off each side to make them work but not 1/2inch worth.

Give-or-take. It was too much to modify. So, I sent them back and ordered another set. This time, they only sent one! So annoying! I had time scheduled with a buddy to get these on today, but nope. I need to measure the replacement now, to see if it will fit. For anyone reading this post, "guaranteed to fit" is just speculation. Link to comment Share on other sites More sharing options...
ratrapp Posted February 21 Share Posted February 21 ive never used anything skp brand so i can't comment on there quality.i have used dorman(not the greatest but better than nothing sometimes)and moog,delphi and even federated line srt and they all seem to fit.i do order a lot off of rock auto but sometimes its better to just bite the bullet and buy local so returning them isnt as big of a deal.

NC Tom Posted February 26 Author Share Posted February 26 I ordered some new ones. I can tell you from measuring them, they won't fit. This is a real pisser! Where the bolt threads through measures approx 2 3/8" wide on the stock ones. The new ones measure 2 7/8" at the same point. What am I doing wrong?

Old and new. The news ones are wider by a good margin. Plus, the old ones don't have those "ears" that stick out beyond the install bracket. Again, is this user error or part error?

Eagle_SX4 Posted February 27 Share Posted February 27 That defiantly looks like part error. Link to comment Share on other sites More sharing options...

This set I ordered from Parts Oasis with a "guaranteed to fit" clause. I don't get it. Link to comment Share on other sites More sharing options...

If it’s a brand that’s commonly recommended, we should know so that we stop recommending that. Moog, TRW, or SKP is probably decent. Heck, even Dorman is probably fine.

Gojira94 Posted February 28 Share Posted February 28 That pic clearly shows whatever manufacturer is supplying the brands he’s bought thus far are installing axle bushings in the body side of the arms. Link to comment Share on other sites More sharing options...

SKP was the first set and the second set was True Drive. The sets were identical. I'll keep looking. Link to comment Share on other sites More sharing options...

That's interesting. They may not even know it's wrong. Or, they don't care. Link to comment Share on other sites More sharing options...
NC Tom Posted March 1 Author Share Posted March 1 Well, I placed an order with Detroit Axle. I know they are not favs around here, but they are the only ones to respond to my questions and they said their arms fit without modification. We'll see.

NC Tom Posted March 9 Author Share Posted March 9 Finally! The Detroit Axle set is only 3mm wider than the mounting bracket. Should be able to squeeze then in. Thank you for all the comments and suggestions. Link to comment Share on other sites More sharing options...
ghetdjc320 Posted March 9 Share Posted March 9 Moog control arms were a direct swap for my when I got a set in 2023. Link to comment Share on other sites More sharing options...
Gjeep Posted March 9 Share Posted March 9 Yep, I've installed several sets of upper and lower Moog's on many XJ's over past several years. Perfect fit. Link to comment Share on other sites More sharing options...
NC Tom Posted March 14 Author Share Posted March 14 @ghetdjc320@Gjeep Glad to hear Moog worked out for you. I saw so many videos of mechanics just hating on Moog that I never even considered them an option. Rock Auto is also an accomplice in these parts "crimes". What I'm reading/watching is that they consistently put a part in a box with a different part number. Don't know how or why or even if that's true. But, it's something to consider and may help explain their low prices. Link to comment Share on other sites More sharing options...
