VA 1967-72 3" drop a-arms use with stock drums or discs.

[VA72C10]

A new set of Chisholm brand 3" drop a-arms for use with stock or lowered coil springs. Get 3"-6" drop in the front of your truck without having to change to disc brakes. Comes with all mounting hardware and new ball joints (one pressed in one new in box (federal mogul made in USA ). 300 plus actual shipping charges (probably 50-60) or picked up near Richmond VA. May also be able to meet/deliver in VA MD DE around my travel schedule. The only other available version of these I can find run 515 plus shipping.

Note: Ball joint part number is 10264. Cross reference shows 71-91 ball joint so won't fit 67-70 spindles. Would need different ball joints for that spindle. IF you have stock 71-72 disc brakes you could use these ball joints to add 3" drop without having to buy drop spindles and change all that out.

How do these control arms mount to the factory crossmember? I am not seeing a cross shaft that is retained by the two U bolts as on a OEM control arm? Are these for use on a after market crossmember? What are the two plates and bolts for in the lower portion of the picture along with the two bushing sets? Thanks

[tallbob]

OK, I think I answered my own question. It appears the plates are the hinge brackets for these arms and they are bolted to the underside of the factory cross member where the U bolts would be. What are the bushings for though? Shocks? Can you use a factory sway bar with these also? Thanks again

Yes, the bracket bolts to the frame. Then the arm bolts to that. The bushings go in that end of the arms and the bolts are what hold the arm to the bracket.

They have the shock mounts. They don't have predrilled provision for a stock away bar but I see no reason they wouldn't work with one. Actually in looking at the pics they do have holes on the side where the bar would mount. I am not home to measure a stock sway bar bracket to see if the bolt holes are correct but can do that later this week.

Will these arms work correctly if I already have 3" CPP lowering springs on my truck? Could the springs possibly be loose or dislocated in there pockets if the wheel/suspension was fully extended? Thanks

They have a spot to capture the spring in the lower cup of the arm vs stock that is just a hole they fit into. So it should stay positioned properly even if fully extended.

Would you be able to provide a picture of what you are talking about regarding that lower spring retention? I cant see it in the original pics. Thanks

Sorry, I was mistaken. I put a new spring I have on it. That's just the angled/raised area that allows the spring to sit level and then keeps it from rotating. It doesn't lock it in.

[tallbob]

Thanks for confirming that for me. So.....now goes back to my prior question whether the 3" drop coil spring could become dislodged going over a dip or bump that would put the suspension at full extension? Perhaps a higher bump stop under the upper arm would assure that scenario would'nt happen? Anybody out there use this style arm with lowering springs? Thanks

[VA72C10]

I truly don't know for sure as I've never installed these. Would have to be an answer that comes from someone who has. I don't think that would happen because the geometry ends up being the same as factory....just the spring sits 3" lower which allows the suspension to drop down 3" lower...so spring should be under the same amount of tension as it is with a stock A-arm. (engine crossmember sits 3" lower than it would with stock A-arms) I don't think they'd be able to sell these if there was any chance of the spring dislodging.

[VA72C10]

I've run and plan to run again a cupped lower A-arm combined with airbags on my next truck/blazer. I know many people running that with no issues...the bags fully deflated are like a 4-5" drop spring. They are bolted in the upper side but simply sit in the bottom cup...they don't come out or dislodge when the suspension fully travels.

I've got 3" springs with the older CPP 2.5 spindles and if I jack the truck up 3/4 of the way up in the front the springs will get loose. I think in order for the springs to get dislodged you'd have to pull a Dukes of Hazard jump to get them to drop, normal driving and bumps shouldn't give you any problems. Way back in the mid 80's I had a 64 Impala that I cut 2.5 coils and it lowered it WAY down, if I lifted the front about 1/2 the way up the springs would fall loose. Never had a problem with them flopping around when I drove it though. The weight will keep pressure on them as long as you aren't Bo Duke....lol

Would you do 260 shipped to 96013 (buisness addres) with a set of stock springs if you have a set kicking around??
