From time to time I have a customer ask me if installing a leveling kit on the front of his truck is going to cause problems. I tell them as long as they don’t go over 2.5 inches there won’t be a problem.
There are leveling kits on the market that go to 3 inches, I don’t recommend installing them. My reason for this is any kit over 2.5 inches will usually cause the tie rod linkage to run at extreme angles compared to the the factory geometry. Same goes for balljoint angles. If you like rebuilding the frontend of your truck annually, then by all means go ahead.
When balljoints and tierods operate out of their normal range of motion it tends to wear them out at an accelerated rate. Not to mention the potential for bump-steer.
Like I said earlier, up to 2.5 inches you won’t have any problems with steering linkage angles, but you will need to have the front end realigned and the steering wheel straightened after installing a leveling kit. If you really need more that 2.5 inches, you really should be shopping for a lift kit instead.
