I have a couple of questions.

1). Just installed a Trailduty leveling kit(Bilstein Shocks, Extended bump stops.
What should the gap between A-Arm and bump stop be?

2.) What is the best tire size for this setup? Will the I-5 Base pull a set of 35's?

Thanks

 

Gap should be less than 1/4", touching is OK. They are not bumpstops, they are dampeners and meant to be part of the suspension system.

Thousands of people run 35's with an I5, even without leveling, and YES they may rub slightly on the swaybar when at FULL turn.

 

285's are my favorite size, some like larger. Stock bumpstops are best for off-road crawling. If on-road performance is more important for your useage, go with the 1/4" recommendation.

Don't forget to get an alignment done every time you adjust your torsion bars!!!

 

A lot of people are running 35s on trucks with i5s, but I personally would do some upgrades to the motor if you want to run 35s all the time. I do run 35s with an i5, and I have done a lot of motor upgrades and I can run down the highway pretty well except for big, long hills
