Front Spring Dimensions

[Kal-El]

PAC Racing Springs® - Coil Over Spring

I can get my hands on a pair of these for real cheap. They're 14 inches tall, and rated at 300 lbs. Trouble is...the spring ID is 2.5 inches and I'm guessing that's too small. What's the ID of a stock spring supposed be? And is the 14 inch height correct? I'm still kinda new to the front suspension area. :shrug:

Hi! this site is great.
talking about front suspension, I was sold a pair of springs and one was longer than the other. Parts guy said this was correct. Anybody else found this?

Too small diameter, spring rate same as stock etc

Kinda figured it was too good to be true. Thanks all.

Um, nope. You were sold a mis-matched pair. They are supposed to be the same length.

Huh...that's exactly the specs for the Moog that I've been pondering. Except as far as I know it's for both sides. The 383# is pretty telltale, I just called and asked about them today. I was surprised to find the Moog at such a high rate.

I found that on Rockauto for the '06 Limited. I'm trying to reveng your search, but it's not so easy on Napa, what model is 2773502 for?

Edit: Found it. 2002 RWD I4.

Weird.

 

[u2slow]

The driver's side is heavier on most vehicles. Maybe the aftermarket is trying to compensate for the extra weight.

 

[ozone000]

Maybe. I just looked up the '06 Limited version. Two different lengths but same rate. That explains why there are so many Moog options for the same vehicle as well. I wonder if these are factory rates or if, like you said, they came up with them on their own. The CRD version is 480 rather than 410 like most think.
