When it comes time to freshen up your Camburg KINETIK bump stops, we got you. Our 2.5 seal kit comes with everything needed minus oil and labor for a complete rebuild. Unlike most others, we supply aircraft grade Viton o-rings that better handle higher temps and extreme pressures. We don’t offer them as an upgrade or option, they’re standard. We also supply the hard bronze PTFE lined piston wear band in our kit, unlike most others. The last thing you want to do is spend time pulling them apart, just to re-use old worn parts.
