What does this swap do?
First thing it does is raise your roll center height (RCH) On a lowered truck the roll center can actually be below ground which is bad for handling.
Second it changes the camber curve. The suspension's camber curve is backwards from where it should be and the top of the tire rolls out instead of in when under compression. The tall ball joints change this to allow the tire to camber in during compression.
Third it fixes the factory bump steer issues on this front end. The steering arm on the spindles is about 5/8" closer to the lower pivot point (ball joint) then it should be. The tall lower ball joint effectively extends this measurement to within 1/8" which almost removes all bump steer.
Fourth it will lower the front end 1/2"
What is needed to do the swap?
The ball joints from Howe, PP, upper control arms for "tall spindle swap" or you can C10 upper ball joints with UB Machine upper control arms like I did.
You can do just uppers, just lowers or both. I would recommend doing lowers first to take care of the bump steer.
There are a few way to go about it.
1)UB Machine upper control arms, C10 upper ball joints (FA903 is the part number for McQuay-Norris and Duralast) and HOWE or Power Performance tall lower ball joints. This would be the least expensive combo. This is the swap on my truck and it came to about $220 or so.
2)SPC upper control arms with PP tall upper and lower balljoints. The arms are more expensive but are a lot nicer.
3)SPC uppers and HOWE balljonts. All top of the line parts and the balljoints are rebuildable. Might not want to pary $85+ per balljoint.
