air shock not holding air

I have a rockshox race rear shock with + and - air chambers.The - chamber isn't holding high pressure and drops to 30 psi in a matter of hours.Ive read that the - chamber cannot be fixed so it looks like a new rear shock :cry:

ive measured the old one and its 160mm x 15mm with a 35mm stroke but I cant seem to find another shock that size.To be honest I would rather go for a spring shock as I don't like the idea of having to carry a shock pump for adjustments while out on it

Can anybody point me in the right direction towards a new shock that's isn't going to break the bank

Thanks

    probably 165x38 in terms of size

    you don't carry the pump around with you either, you set it up and forget about it.

    what is your actual budget and what bike is it going on

    How have you worked out it's losing air?
    The - chamber will be tiny, so just by attaching a pump the pressure will drop significantly just priming the pump.

    If it is always losing the same amount whenever you check it there is nothing wrong with.

    i put 200 psi in the + chamber and then 100 psi in the - chamber.The shock feels just right but after a few hours the shock is rock solid and the - chamber drops to about 30 psi
