F150 4x4 front alignment specs
Looking for front wheel alignment specs that will reduce the wander so common on IFS front suspension trucks when driving straight. The truck has a Superlift 4 inch kit with superrunner steering system and the long radius arms. Please help.

F150 4x4 front alignment specs
There will be specific specs for your lift and application. On my 91 F250 with a 6" lift, specs are:
Right Side Front
Camber: Nominal 0.25 deg. Min -0.25/max 0.75
Caster: Nominal 4.25 deg. Min 2.00/max 6.00
Toe: Nominal .03 deg. Min -0.10/max 0.16
Left Side front
Camber: Nominal 0.25 deg. Min -0.25/max 0.75
Caster: Nominal 3.75 deg. Min 2.00/max 6.00
Toe: Nominal 0.03 deg. Min -0.10/max 0.16
Cross camber Nominal 0.00 -0.40/0.40
Cross caster Nominal -0.50 -0.90/-0.10
Total Toe Nominal 0.06 -0.19/0.31
Set Back 0.76 deg.
Your set up will more than likely be different and a spec sheet should have come with your kit. Mine are no longer applicable since I have done cosiderable modifications to my front axle(swap) and shackles(reverse shackle set up),along with steering, shock location and spring perch mods. Superlift has always been very responsive in answering all of my questions,even after modifications(although they are a bit more cautious). Later,

Also, What brand, type, and size of tires are you running? Also which shocks? And are you using Superlifts Camber caster eccentric adjusters? I may be able to help. I had a very considerable wandering prob with my F250 when I first took it skyward. In fact on the drive home,(up a winding mountain road) I was just sick at the thought that I had ruined my truck, (I had to fight with it every mile of the way), and paid several $K to do it. It handles very well now.

H8monday,
Thanks for the response.
Tires BFG All Terrain 33 x 9.5 x 15.
1st try at shocks were those provided by Superlift with the 4" kit. I now am using Edelbrock Performer IAS. Truthfully I can't tell the difference between the two.
The upper ball joint adjusters are similar to Superlifts, the bushing rotates allowing adjustment of both caster and camber, or should I say a compromise.
What did you do to fix the wandering? It gets quite annoying at times. Any special alignment angles?
Any help would be appreciated.
Thanks
