View Full Version : Offset a-arm cross shafts and Guldstrand mod

I searched the archives and didn't come up with a definitive answer on this. I am considering doing the Guldstrand mod to my frame and running Global West Del-A-Lum bushings throughout. The quetions are as follows:
1) Global West sells a kit to weld studs into the ends of the cross shafts for better bushing retention. They reccomend, however, the offset cross shafts they have with the studs already in place. For ease of installation I considered buying these-but how will they work with the Guldstrand mod?

2) I understand some GM cars came equipped with "studded" cross shafts, what were the applications and would any of them work on the Camaro?

3) Should I just do the Guldstrand mod and weld some studs into my existing cross shafts to avoid potential geometry problems associated with combining the offset shafts with the Guldstrand mod?

As a side note, I saw offset cross shafts listed as replacement parts for the Camaro front end on either www.wrenchhead.com (http://www.wrenchhead.com) or www.carparts.com (http://www.carparts.com) not too ong ago, but I don't know if the had bolts or studs for the ends.
Thanks for any insight!!

I have tose Global West shafts with Del-A-Lum bushings, and the guldstrand mod. Works killer. Best one out of the few setups i've had.

The male studded ends are a good idea if you have any of the aftermarket bushings.
The aftermarket type bushings will tend to unscrew the bolt type shaft ends. I had to saftey wire my bolts when I did the bushings.

I have the weld in adapter studs from GW, they say to heliarc weld them in place.
I don't see any reason to not use the offset Moog, "problem solver" shaft.
The number is K5250 for the shaft "kit", you need two "kits" per car.
The book does not say what a "kit" consists of.

Bret,

I have a 69 Rally Sport and installed the Global West Del-u-Lum bushings on the upper and lower a-arms. I also did the Guldstrand - Trans Am mod.

A few thoughts - I really like the Del-u_lum bushings - even though they are a little expensive. I choose to weld the bigger threaded shaft ends onto aftermarket TRW or Moog shafts (they were thicker and I wanted to preserve the factory shafts). I don't know how the a-arms will fit with offset bushings? From my experience you really need to fit-check all this stuff! I'm a perfectionist and have a very nice car.

After carefully doing the Guldstand Mod (which I really think is a 68 Penske/Camaro mod) I moved the A-Arms completly up and down with the front coil springs out and found I needed some more clearance mods -to the shock tower area but I also needed to grind some material off the upper a-arms - the arms hit the frame below the bushings. I didn't need to remove much material but I recommend you check this I'm sure it varies form car to car.

I'm not sure if the offset bushing helps of hurts a-arm clearance?? Bottomline no matter what anyone tells you check the clearance on your car! With the the A-arm mod the arm moves very close the frame.

On last thing I decided to install poly bushing on my rear leaf springs instead of the del-u-lum. I think the front a-arms benefit from the del-u-lum more than the rear.

Good luck,
Dave

Ok, so I know they will work together, just need to figure out if I want to go with Global Wests or the Moog replacements-any idea if the Moog's are studded?

I was under the impression that the shaft "kit" did both sides-turns out that the price is for one side only. I might look closer into doing the weld in studs. Unless I can get a good deal on the Moog parts!! Thanks guys!

The book does not say what comes with a kit. It might include bushings?
I'm not sure.
The illustration shows a stud type end.
It's probably the same part GW sells.

Ok, bought a Moog offset shaft for comparison. It has stud style ends and comes with two new rubber bushings, two nuts and two retaining washers. It was $42 plus tax. The GW shaft appears to be drilled for a cotter pin and comes with two cotter pins and two castellated nuts for $52.

David, could you double check the part number? They gave me k5250.

Also, what's the opinion on pinning the nut? Should I drill the shafts?


PS. While you have the Moog book out, could you see if they list a number for the large diameter center link? I'd appreciate it!

Yeah the GW kit "shows" the shaft's being drilled for cotter pins, but they aren't. You need to do that mod yourself.

Sorry, I had an extra number in there...
I have corrected it.
The castle nut with cotter pin is a good idea.
You could maybe double nut the shaft as an alternative.
There is no center link from Moog, you might try Chevy parts. I think they are out of them. I don't know how important the heavy centerlink is. For a big block it's probably a good idea.
