Moog CC665 on an Avanti
There has been a lot of discussion about the Moog CC665 springs on the front end of Hawks. Does anyone have experience with them on an Avanti.
I will need a new set for the 74 Avanti and at the current price they are an excellent buy.
Bob, what is the application of that spring? When I did my brothers 63, I used rear springs from I believe a 78 Buick lesabre. I can check them out for sure if you'd like, as my memory isn't recalling the exact application I used. They really worked well though! Bill

The engine is out and I don't want to deal with a spring compressor but I want to redo the suspension components in the heated part of the pole barn.
If they drop the front a bit that would be fine.
Thanks again, Bob
try a forum search of Moog CC665.

That's why I asked.
Bob, I'll check it out this evening and get back to you most likely tomorrow. Bill

BTW the last of the Lark types (65-66)..., with the Chevrolet engines..., did they have a different spring rate? I heard the Chevy engine is quite a bit lighter than the Studebaker engine.

I put them on my Avanti last year. I also rebuilt ALL of the front suspension, including new Derlin bushings. That said, my car drives a LOT better than before, the 50 year old grease is gone, and I used a synthetic grease along with the O rings in place of the cork gasket. My car "hugs" the road (in my opinion) as I do not have power steering.
Go for it!

OK Bob, I got the info from my brother. As stated above the Moog # is CC-655, and it was used as also stated above. When i put the car together I also rebuilt everything in the front end (along with everything on the car), and used these springs. I got them from NAPA, which # is 277-5271. Same exact spring, so no worries about different rates etc. At first the car sat higher in the front, but after about a year (very little driving in that time) they settled in and sit just about perfect now.The car rides excellently, handles very well, and is a blast to drive. Hopes this helps you out my friend, Bill.
Thanks for taking the time to find the data. Between your's and Jim's advice, I'll order a set of CC655!! coil springs or equivalent. That will let me remove the old corroded springs with the engine and tranny out. I just don't like using spring compressors under an Avanti. I'll now rebuild the front suspension in the warm part of the pole barn.
