Ford ranger lift

Yes, Lift kits have an affect on ALL of your suspension and drive train parts. you are putting stress on everything that wasn't designed for it. It will also likely wear those tires rapidly also. expect more maintenance.

I do between 30 and 40 lifts a year. I have not had a single truck break or wear out prematurely. As long as you don't drive the truck like an animal.

I can say from experience that a lifted vehicle will have more wear on the drive train than a non lifted vehicle causing pre mature failure of many parts, Ujoints, cv joints, wheel bearings, cv boots, steering parts, rear end gears, and the list goes on. I have even seen where drive shafts have fallen out while driving because of these kits. No, won't happen right away, but stuff will wear sooner, much sooner in some cases, but at least you can have the benefit of poorer gas mileage to go along with it.

I would like for you to tell me how a lift kit affects gas mileage. 20 years ago lifted trucks were prone to failing u joints and driveshafts. The el cheapo kits from e bay are also good for breaking parts. Having your buddy install a kit in his backyard while downing a case of beer is not the greatest plan either. A professionally installed modern kit. Which has correction factors figured in for pinion angle, proper alignment geometry, and quality parts will give you many years of trouble free service. I have trucks on the road for better than five years now. Not a single driveshaft has fallen out.

Steve, I had no intention of insulting your profession. I have simply witnessed some problems due to lift kits. Perhaps they were cheap or not properly installed, but I have seen the problems none the less. I stand corrected, the lift itself may not affect fuel mileage, but the oversize tires with more aggressive tread will.

you may have to add some to your drive shaft if you lift it way high but thats the only reason i have ever seen a shaft fall out i've been 4 wheelin for 45 years now

Lifts will reduce fuel economy due to poorer aerodynamics. The biggest fuel economy factor is the larger tires.
