Used the harbor freight set and they worked just fine. I did, however, lube the threads with a high pressure grease before using.

 

I'd need to buy those though, i can (free) rent the autozone ones.

 

That tool looks terrifying. Maybe easy to use, but there is no lock. Those springs they're compressing in the demo are as soft as marshmallows.

 

I "rented" this exact tool and actually bent the main shaft when trying to compress my springs. I returned it to AutoZone for my refund and pointed it out, they refunded me the full price anyway. I went to a local suspension shop with my removed struts on a Saturday and got lucky, they had a wall mounted spring compressor and got the springs swapped out. BTW, I was installing Bilstein 6112s on the front and LOVE them!

 

Shankly heavy duty spring compressor worked great on mine. I needed it to get the stock struts out as well as build the new Bilstein's.

 

These truck springs are stupid stiff and scary to compress. Nothing like the soft Jeep springs I'm used to dealing with.
Safety first!

 

I've used this type and it worked quite well. Much safer than the two bars that clamp onto the springs. Just need to make sure the threaded rod is well greased and don't use power tools to compress/release the springs.

 

I bought rough country coil overs 2.5 level assembled for 330.with shipping and my Ford Dealers installed for 300...600 total gave me a done deal..

 

Local Ford dealer did mine for about $200. Money well spent for me.
