So I just got a set of free rear shocks from a 97 landcruiser with only 80k on the ticker. I'm planning to replace the rear shocks on my 97 4runner with these and add his used front coils. My only question is that these rear shocks have what looks like a retaining wire to keep them held together. I'm not too familiar with suspensions and I'm supposed to take this wire off for more flex or does it stay because it has a purpose? Thanks for any advice.
