Rock-Auto: whats the difference?

[Creager]

Check out this picture from the Rock Auto online store..

What is the difference between the FOUR-HEAVY DUTY SPRINGS and the HEAVY DUTY SPRINGS?

 

[FROADER]

Just a guess, but maybe FOUR-HEAVY DUTY is for the 4 door and the HEAVY DUTY is for the 2 door....?

 

[Creager]

i was thinking that or maybe its for a four inch lift?

I cant get ahold of anyone there, they havent reasponded to my email, and ACDelco doesnt have anything under that part number?

turns out there is no difference.

One "FOUR-HEAVY DUTY" version is actually directly from ACDELCO. and usually dealerships would take advantage of that... according to the RockAuto rep.

Ah ha...
