Newb Spring question

ddvette9

Currently have 46,000 miles on factory suspension. Picking up swift springs from friend with his shocks which have only 15,000 miles on them (he just switched to BC coils). I understand springs on stock shocks limit life so I imagine putting them on my 46,000 mile shocks is probably a waste. Is it even worth it to switch to his 15,000 shocks with the swifts or is it best to drop springs on fresh shocks and if you cant then go coils?

I daily drive and am a student so I am looking for a good cheap solution for suspension and I know swifts are the favorite springs on here. Let me know what you guys think about my two shock options. I dont track or anything, just cruise around town.

How long are the swift springs active and good on a stock shock. Dont really want to take his shocks from him if its a waste. He is giving them to me for a deal and then i can keep them in my house until I save up enough for a shop to install them. Thanks
