Cranking up IFS torsion bars to increase fenderwell clearance for taller tires is an old trick. Unfortunately, this "free" lift limits suspension travel and compromises ride quality. A better solution for leveling the vehicle's front and clearing taller tires is to replace the OE torsion-bar "porkchops" with reindexed ones. Although this method isn't free, the reclocked porkchops allow more liftability and additional suspension articulation compared to cranking up the OE adjusters. Many suspension companies now offer reindexed torsion-bar adjuster-key kits. In fact, several even get the keys from the same factory. Truck owners should check to see if the aftermarket adjusters are cast or forged. The OE keys are cast steel, but quality aftermarket forged replacements are 25 percent stronger. They cost more but are worth it - hanging larger, heavier tires on the knuckles adds stress to the rest of the front suspension.
