MOOG CC springs  and the V6 SHO Taurus

-----

During a recent suspension overhaul on my '89 SHO Taurus, I found myself dealing with a lot of part numbers,

and a lot of confusion. THIS is the final say in the MOOG CC spring fiasco.

-----

The MOOG CC (cargo coil) springs are designed as an improved factory replacement coil spring for regular Taurus'.  They are progressive rate (whereas stock is linear) and are much stiffer overall.  Many auto chains will not find the correct Moog coils if they search by application simply because Moog (for whatever reason) does not recommend the use of the Moog CC springs on the SHO Taurus.

You MUST search by PART NUMBER.

- Part Numbers -

Lets look at the part numbers first. I will provide both the MOOG and NAPA numbers.  As you can order the same coils, as MOOGs from some sources or through NAPA, but with NAPA part numbers.

MOOG:

Gen I: Front CC862 Rear CC839
Gen II: Front CC858 Rear CC859

NAPA:
Gen I: Front  NCP2775235  Rear  NCP2775216
Gen II: Front NCP2775236 Rear NCP2775318 

There are Gen 1 ('89-'92) and Gen 2 ('93-'95) specific Moog coils. You can, however, put Gen 2 specific coils on your Gen 1, or just the opposite, Gen 1 coils on your Gen 2.

- Spring Specs. -

Now that we have the part numbers to look at, lets look at the differences between the Gen 1 and Gen 2 specific parts.  These specs are from a MOOG parts database, courtesy of Louis (LaTechSHO).

GEN 2, FRONT:

MOOG CC858 Coil Springs (pair)

GEN 2, REAR:

MOOG CC859 Coil Springs (pair)

The ride heights and spring rates change when going from Gen 1 coils to Gen 2 coils.  However, front MOOG coils no matter the part #,  right out if the box will ride VERY high.  Because of this, I chose to cut one coil off the front springs. A few others have cut one and a half with great results.  I chose to stick with a stock style strut (monroe sensatracs) so cutting more than one coil was out of the question.
