Is an adjustable track bar needed if going with a 2.5" coil lift with 3/4" front coil spacers added to it? If so front,rear, or both? Thanks

 

While I am not absolutely certain, I think you are going to want adj front and rear trackbars with the lift you are working on. I put a 2" OME shock and coil lift in last weekend and my front axle shifted about 3/4" and the rear axle shifted 1/2". You can get away without the front and rear adj track bars on the 1" and 2" bbs but not with a shock and coil lift. Anyone else, please feel free to correct me if I don't have my facts straight.

 

I bought a (superlift) adjustable track bar for the 2.5" skyjacker spring lift, and it doesn't adjust enough to use (the min. is more for a 3" - 4" lift kit - next purchase I guess). The stock track bar leaves the axle closer to center so I put it back in. In the rear I used a BDS relocation bracket works awesome but the axle is out 1/2". Liveable so I'm not complaining, as the ride/steering is decent. If I did again I would buy a adjustable track bar front/rear that has LOTS of adjustment from stock up.

Keeping The Axles Centered Is Important For Stability On And Off The Road

Also When Using Other Wheels And Larger Tires This Will Also Prevent Any Rubbing When The Suspension Is At Full Droop Cause You Are Maintaining The Correct Geometry I'm Sure Some Will Explain What I Have Said Here
