Jeep ZJ rear coils? Or only TJ coils? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Low & Slow · 06-06-2011, 09:55 AM

I've been searching for exactly what kind of rear Jeep coils will work to lower the rear about 4". Ran across a post referring to Jeep ZJ rear coils but thats it. Just one single reference to them.

Is anyone actually running them? There are plenty ZJ's in my local junkyard and zero TJs so if this is a confirmed method I can grab a set this week. The ZJ is the V8 chero so I'm having a hard time believing that the V8 springs would lower the rear. Wouldn't they be beefier?

Any input would be great : )

I would like to know this info myself.Sounds like a nice low buck drop option.

\\ its TJ

They really dont work, way too soft. Bottom out on everything etc etc

So why are some guys swearing by TJ springs?

Im confused lol either they work or they dont.

Jeep Wrangler TJ's seem to be the ones that fit our trucks like these http://cgi.ebay.com/ebaymotors/Jeep-...item20b9efe953

They bolt in etc etc but they are THIN you CANT HAUL ANYTHING AND YOU WILL BOTTOM OUT FREQUENTLY.

I have some i'll sell you cheap if your set on using them

Jeffs70 · 06-06-2011, 04:06 PM

apparently with some they bottom out, I have never tried them. I also could see them not working if you have a tank in the rear of your truck because these springs are much softer then our factory ones.

Jeffs70 · 06-06-2011, 04:07 PM

I would go with what oldblue says hes tested them it sounds like lol

oldblue1968chevy · 06-06-2011, 09:46 PM
