1. Do I need to get an allignment with a straight axle?
2. How much does it cost to go to a dealership to get everything recalibrated?
3. How much will it kill my MPG's with 37's?
4. I noticed on the 6 inch lifts with 37's that the rear tires sit super close to the outside of the wheel wells. If you tow a lot will the tires rub in the rear?
5. And lastly...once I take off my stock rims and tires how much could I sell them for? If anyone is interested in the stock running boards or the rims and tires hit me up on my email at oomcneilranger@aol.com |
1. Toe is unaffected by the lift and the castor is set by the radius arm drop brackets included in the kit. Typically the only adjustment required is centering of the steering wheel via the adjuster at the lower end of the drag link. The Rize 4-link systems are more complex and do required alignment in order to achieve proper castor.
2. Your local dealer can recalibrate for tire size and for the air pressure sensors but pricing will vary. ($25-$150 est.)
3. Fuel mileage will not be drastically affected. Most people exaggerate the change because they do not compensate for the inaccuracy of their odometer versus the true distance traveled if they did not recalibrate for the increased tire size.
4. The Rize radius arm system includes offset blocks which center the axle within the wheelwell. The oe rear springs are very flat so there is also little rearward deflection under compression. The amount of weight you tow will obviously have an effect on this but I have not had any customer comment on a rear rubbing issue. Here is an example:
5. The stock 20s with tires bring $1200-$1500 in my area. Expect less for 17s and 18s.
Let me know if you have any further questions.
