I know there's the thread in the general section about installing coil springs, but I figured since this install is specific to the Carry, that I would start a new thread here. I purchased a set of AFCO 275# springs from Summit Racing ($44.00 each I think) a while ago, and finally had a chance to install them today on my DB51T Carry. I found the easiest for me to release the spring tension was to load the spring using a floor jack (truck placed up on jack stands), taking the nut off from inside the cab using a 3/8" impact, and then lowering the jack slowly to release the stored energy. I then took out the spring by tipping the strut towards the outside of the truck. These AFCO springs are for coilovers, so are flat on the bottom, so I matched up the location of the square cut ends on the OEM springs (both ends to ensure equal free height), and then carefully cut them with a zip disk, smoothed the ends over with an abrasive disc in a die grinder, and was ready to go. The install was a bit harder than the removal, simply because the strut rod wanted to slide into the strut canister, so I gently clamped through the coils and onto the rod with needle nose vice grips, to hold the shaft. Also keep in mind that the upper strut bearing to strut rod is keyed (by using a large flat area on the threaded section of the rod).....or at least mine are. I lined everything up, raised the strut with the floor jack and got it assembled. The second one went even faster. Basically an hour and a half job.....and I gained 2" without any strut spacers.
