Default gr2 kyb

ok im looking into buying struts and i was wondering if the kyb gr2 stuts would be fine with my eibach pro springs? also i might switch to hr race springs in the summer or fall would these struts be able to handle these springs? im probley never going to adjust the struts so thats why i didnt look into the agx struts and im low on cash and my struts are done and need replaced

GR-2 shocks are pretty much OEM replacement. Probably the only lowering spring it could handle would be something like the H&R OE Sport springs, and even that would be questionable.

The new Koni STR.T shocks are an entry-level shock, and I would not expect them to hold up to any sort of "race" spring. However I have no experience with them.

I had H&R Sports when I first got my Koni Sport shocks, and I thought it was total crap. The H&R Sport springs were way too soft for the amount they dropped, and as a result the car bottomed out all the time.

why is this? i've read that a few times that the GR-2s are essentially OEM replacements and that it would be questionable to pair them with any other spring that's not OEM.

what about the Eibach ProKit springs or H&R OE Sport springs paird with the KYB GR-2 struts "questionable"?

Why is what? That's just how they are, OEM replacement shocks. Pretty much like some Monroe or Gabriel shocks you might pick up at AutoZone.

what he's saying is since the eibach pro kit doesnt slam the car why wouldnt the gr2's work? i can see hr race springs or something that lowers your car 2.0 inches nnot working but the pro kit and hr oe sport dont really drop the car that much... but anyways im stuck between getting tokico illumina shocks or koni sport shocks... can the illuminas handle hr race springs or jus go with the sports?

For how long? I bet you'd be amazed at the difference in ride quality if you switched to some new high quality dampers like Koni Sport or Tokica Illumina's right now.

the illuminas can handle the race springs, but if u can afford koni yellows get those, but if not illuminas are fine also

For the love of god, they are struts, not shocks. my '02 oddysey has shocks in the rear. ridgelines n mdx's have shocks in the rear.

but we sell Kyb Gr2's as a replacement strut and shock for many makes n models of import and domestic vehicles. They will work with mild drops. I've installed them on 1.5" drops and have had 0 issues with it and 0 warrantee comebacks with lowered vehicles.

The problem is when people try to mate them up with real aggressive drops or slamming there coilovers. The GR2's just aren't valved for that kind of drop n abuse.

But yes, they will work fine with your prokit.

Really? All integras and any civic older than 01 have shocks. A strut is defined as a structural suspension component. Just because they do not look like the shocks on your odyssey does not make them struts


The reason why we dont recommend using OE replacement shocks on any drop is because they are designed to be used with oem springs and spring rates. Most if not all lowering springs use higher than stock spring rates thus drastically reducing the shocks ability to handle the spring rate and drastically reducing the lifespan of the shock.

Stop posting incorrect information. All Hondas prior to model year 2001 have shocks at all 4 corners. Coilover-type shocks to be exact.

The 2001 Civic and 2002 RS-X were the first Honda models to incorporate McPherson struts at the front end of the vehicle.

At least they still have coilover-type shocks in the rear, and some of the Acura and Honda Accord models are still using double-wishbone up front with shocks all around. Most Toyotas, Nissans, Mitsubishis, and other foreign and domestic family cars use Mac struts at all 4 corners of the car *barf*

I see... I wouldn't expect those shocks to hold up for much longer than a year.

How do the GR2s compare to the AGX? I have KYB AGXs w/Eibach prokit springs, but now that I've moved, the city streets I drive on are a bit too harsh for this set-up. I plan on installing OEM Showa shocks or possibly GR2s - but I'm not sure which springs would work best if I went w/GR2s - my OEMs, or Eibachs.

I had that same set-up on my 99 EK for about 4 years and I found adjusting to a softer settings in the city helped soften the ride, although i liked it rough.

The pro-kit will settle over time. At some point the Eibachs will wear out the GR2s. After 4 years they started to wear out the AGXs.

GR2's are OEM replacements. I just installed some on my girlfriends EK.. Shes lowered about 1.2" on Goldline Yellows. They replaced her BLOWN OEM shocks haha.
