BC ER Shocks
 

I bought the shocks from another member, he and just had one of the fronts rebuilt. When I received them the other front was leaking so I stored them and contacted BC. Long story, BC is no help unless you want to send the shock to them and get charged $250 each plus shipping. During this time (4 months of trying to get any info from BC) the freshly rebuilt shock started to leak. This made my decesion to have them rebuilt again easy, No way, close to $600 with the shipping to have them leak again.

Fast forward to now, 2 years, I could not find anyone to work on them. All shops I contacted replied the same. BC not a bad shock but we can't work on them.

I took them apart yesterday and found a small "O" ring installed wrong! I will try to show this in the photos.

Last BC pressure system is the reason no one will work on them. Any other shock has a valve to add pressure after rebuilding, BC uses a rubber plug and a hex set screw. I will be installing a valve during my rebuild and service. All the other parts inside are just standard "O" rings and packings.

As BC would not give me any info on oil weight, Qty, or pressure I'll be using other data to service them.

I should end up with a much better shock when I'm finished.

This is how it should be!

So was the reservoir what was leaking and what you are rebuilding? I have a set of BR ER also, BTW.

The leak was at the adjuster on the reservoir. The rear shocks have not leaked. All 4 have the custom valve stickers from RA. So someone opened them up to change the damper stacks. Could be the custom work is only on the fronts? Rears are good from the factory?

I do have the rears on the car right now, with HKS hypermax III in the front. The rears do make more noise then the HKS as there is no rubber in the BC upper mount.

Update-there are broken parts inside the ext res assy leaking. BC will not sell me anything but a full built shock body that I install my ends on. $225 each with a 6 month warranty. SO I CAN FAIL AGAIN! Taiwan Crap. If I can get the broken parts out I can make new ones and the shocks will be fully re-build and I pass what I have done to any one that wants to not get raped by BC. If you need rebound and compression adjustment stay with KW-3 or higher. I wish I had.
