JIC Suspension-Project, the coilover I’ve been using it for daily driving and autocross. Last year my JIC leaks, the oil seal wear out…so i ask one of my Sifoo, EFN, from zerotohundred.com, regarding my problem. So we did a little DIY disassembling the JIC.We took one day for us to do it, we are newbie …but we manage to repair it…kudso to us.

A year passes a way, now my JIC leaks again, maybe the oil seal not good enough.

So the first thing I bought, is a new set of oil seal for the absorber cartridge from the oil seal shop, lucky I manage to get the desirable thickness .

oil seals details :
Left side : new set, RM10 each
- size = 20mmx42mmx7/7.5mm (better by the look)
Right side : last year set, RM3 each
- size = 20mmx42mmx10mm

both are from SOG.

The new oil seal can withstand the pressure from the coilover impact, wherelse the old doesn’t, that’s what the salesman told me. But by the look of the material, the set is much more stiffer and thicker.



see the 3mm differences…well the new set closely match the original JIC oil seal…


29th October 2006…
Now the coilover has been dismantle.
Check everything and found out that…


this little special oil seal from A1…at the bottom...

already torn out…no wonder there’s a free play and…"klakkk…klakk" sound…

The next day i went out to find the oil seal replacement , i went to suspension specialist, RS ONE for advise…to my disappointment…they don’t sell this special kind oil seal…plus they said…"if you all know how to repair it, sure i’ll close down my business…" heeee…

  Never mindsince that i needed my coilover before 4th November for autocross event, so i’ve to send it to them to repair it.
Danny from RS One asked me what’s the setting i wanted…Drag, autocross or track…so i said for autocross, a little bit soft then original, maybe 80% then stock…but he remind me that JIC spring are way too hard for soft shock absorber, so he told me that he will set it up the best he can. Soo…sent it on monday, the 30th Oct, got it by Thursday 2nd Nov.

Superb !!! The next day, put in every back in…setup alignment and chambering…then when out for a test…wow…my JIC is "alive" again…dampering was nice, no more irritating sound, better then what i’ve expected…worth it for RM400…Thanx Danny…

Almost forgot, the absorber valve…taken apart from bottom part of B1.
