Heck IDK. These were springs I saved from the donor truck that my '91 got it's 460 from. I put em in my '95 (302 engine) because my son wanted to level it.

 

The cc822 is the part number that is listed for your truck with the AC, and the cc824 is the heavy duty version. The spring rates are the same between the two of them and the length is a little over a half inch diifferent. The stock replacement is most likely going to be the cc822.

 

Thanks for getting back to us with that info.

We reached back out to MOOG with the confirmed information and made sure to mention the factory dual front shocks. The tech we spoke with has been with MOOG for quite a while and provided some solid clarification.

They also shared an interesting tidbit about the dual-shock setup that we thought was worth passing along. All of their springs for the Twin I-Beam trucks are cataloged as not fitting dual-shock applications. They said the reason is their replacement springs typically have a slightly larger outside diameter than the factory spring, which could create a potential clearance issue with the auxiliary shock. That said, they have had customers run them successfully with dual shocks, they just can't officially guarantee clearance.

Based on your truck’s configuration, MOOG confirmed the MOG-CC820 is the correct standard replacement.

Let us know if you need any further assistance, we'll be happy to help.

 

So, the ones that the Moog website lists for vehicles without A/C is actually for vehicles with A/C. No wonder we have a hard time getting correct and quality parts anymore.
