Coil Over help

I have a set of Cusco Zero2 coilover that i want to check to make sure they arent blown. How would i go about doing this? I know it seems like a n00b question to ask but i have no idea:dunno:

 

take them off, take the springs off and push down to compress the shock body/shaft. It should move slowly and evenly under your body wieght. If it sticks a little or makes strange sucking sounds then they're done for and need replacing/rebuilding.

 

OK but you cant really push down on them lol

 

there ya go :biggrin:

 

well they dont stick but they do not rebound once compressed

 

Sound like they need a rebuild. Most coil overs I see need a rebuild every two to three years. Unless you spend the big bucks like 4-5K

 

Yeah, if they don't come back up then they've lost their gas charge.

 

they aren't gas charged so they dont rebound all springy like stock ones or gas struts.

however what sucks the most is even if they are blown Cusco does not rebuild or repair their struts and almost nobody will, and the ones who will charge a ton of money for it.

 

how much does that cost?

 

Most of the ones I have dealt with are under warranty.

 

So what are you saying kevin?

 

Unless you can get Cusco to rebuild them it looks like you will be giving your coil overs to me.

 

replacements for my k-sports were $100 each. Cusco I imagine is likely 4x that.

 

No i wont

 

Hey I tried.

 

ok where would i even go about finding that info out?

 

I go rid of my zero 2-r's for the reason that almost all cheaper coilovers have much better options for rebuilding or replacing struts.

like i said before cusco will sell you entire replacements struts at list price, but nothing else. might as well just buy another set if they're all blown, or go to a company that cares a little more about its customers (found this out the hard way too)

 

Some one help me understand what i am looking for... they go down smooth and steady but do NOT rebound

 

They should not rebound at all. There is not gas charge to push the piston back up.

The only real way to check them is to have they dyno'd on a shock dyno. Other than that pushing down on them with your hand will not be able to move the piston fast enough to check the condition. If they feel uneven when pushing the piston down with your hand then they are far past dead.

 

ok its an oil filled strut, usually they have to have something pressing against them in force to rebound. konis are the same way, you push them in with your hand and you have to pull them back out again, but if installed on a car they rebound fine.

do they stick or not rebound when put on the car?

 

Thank you thats all i was looking for...

 

I havent done that yet i was waiting to see if i should rebuild them first.. I think ill throw them in and see what happens

 

Why do you think there is something wrong with them?

 

Some people thought they were blown but after inspection and running to the RUF shop they are fine

 

Joe and Chris gave them the ok?

 

Yes I talked to Alistars dad

 

Wow Joe looked at it. He is not a big fan of WRXs

 

I want my pillow ball mounts back
