Hello all, this is actually my first post so bear with me! I have been reading constantly on this forum after being introduced to it while looking for GC/Koni info. It is SO nice to be able to find good reliable info that doesn't involve a "drift bias".

Anyway, surfing Ebay I found a GC kit for "95-99 Nissan 200sx and Sentra". The sleeves look similar in length to the 240 kit, and the springs look about 6"...

Does anyone know the differences in the kits?

Sentra sleeves are 4" all the way around, and the 240 are 4" F/ 2.5" rear.

240 off the shelf kits have really short springs. What spring rates does the Sentra have...or PM me a link and I'll look at it.

Okay, but if I use your 86xx housings for the rear eventually then 4" would be the right length correct?

What I was really interested in was the diameters of the sleeves, and also the top hat designs. If those are the same then they could be used on the 240 without any trouble i would think.

I don't know the spring rates on the auction, but I figure new springs shouldn't be a problem to get cheap.

PM sent.

He's right. That height difference is nothing a sawzall can't take care of. FWIW, the sentra guys actually use GCs more than the 240 guys do. I found a used GC kit from a Sentra on sr20forums that I got for $80. That included the springs.

Nice, Why is it that I can never find those kind of deals?:D

I'm getting a set of Deviant front housings, and maybe the rear set later when I have the time/money to set that up. So I should be able to run the 4" sleeves for a while on an eclipse shock and not mess it up by bottoming out on the sleeve, if I read it right on another thread here.

you have to look for them when you don't need them. I was looking for something else, saw that deal and jumped on it. I didn't need them at the time, but knew that I was going to be starting a project soon enough where I could use them.

BTW, right now is a great time to be searching ebay for circle track throw-away parts, which includes 2.5" sleeves and springs.

Agreed. I've bought some circle track sleeves from Ebay for like $50, I got 4 sleeves, top hats, and matching collars. They're used but still in great condition.

So, to sum up,
The only difference in the GC kits is the length of the sleeves
The diameter of the shocks is the same.
The 4" sleeves all round will work with the Deviant 86xx housings.

Is all of this correct?

I know the spring rates will be different but I don't see that as an issue with the abundance of them out there. I just want to be able to widen my search criteria on Ebay and the like, to include sentra stuff.

Nope

GC makes different diameters for different shock brands. KYB is larger OD than Koni IIRC.

I was sure they sent various sized 0-rings or adapter to make the sleeves work with varioused sized shocks/struts.

The GC kit on my car right now was originally purchased for my B13 back in 2002 to work with AGX's. They worked just fine with the koni yellows in the rear, for the short time I had them on there, after I bought the needed C-collar from GC last year.

Yup, you are right, I forgot about the ORings

Yeah, but now with GC being so rough on it's customers I don't think I could get small stuff like that anymore. Hmm, well maybe I can find the o-rings somewhere else.

I bought a assortment of 0-rings from the local plumbing store ;).

I think the piece in question is a machined bushing, not really an o-ring. The rear Koni's are something like 1.5" in diameter, and the bushing takes up that space. When I switched to the 2.0" diameter Bilsteins, I just popped that bushing out and the sleeves fit over it snugly.

What did you have to do to adapt the B13 kit to your (i think s13) 240sx?

The black collar is what I had to buy from GC to get the sleeves to seat properly on the koni yellows. I still have them and there forsale since now I have the 8610's in the back and don't need these.

With the 8610's and Richards housings, they slide on with just a very small 0-ring to keep things from rattling.

Cool, I might PM you about those, if I can get this to work.

One last question, Richard said something about the top hats being different on a 95-99 sentra. Do you have any pics of them?

Bringing this back from the dead....

Can anyone tell me the length of the springs that come the the 240sx or sentra kit? Or it is that you can specify the rate along with spring length at time of a new purchase?

You can specify within reason when purchasing new from GC.

Sentra kit is 7" springs all around IIRC. I can't remember what the "standard" 240 spring lengths are, since I've never ordered them.=)

Good to know, thanks! I'm still debating on which route to take. I'm planning to do the bilstein setup for the daily in the coming up summer and can always source out springs and sleeves separately, but was having trouble with finding the upper hat within reasonable price. So in the end, it cost just as much as buying a kit. Just hoping that it wont be much trouble in ordering since I've heard horror stories with their bussiness ethic from others and here as well.

240 kit

5" front springs
7" rear springs

Yeah, you can request whatever flavor you want, you might not get it. I didn't
