gear swap ?

I'm planning on swapping my 3.73's to 4.30's on my 2001. What I'm wondering is should/do I need to, reprogram the computer? I was also thinking of getting a tuner from 5 Star. Can I change it with that or can they change it when they program it? Headers and freer flowing exhaust are on the list too.

I had a gear swap to 4:30 in mine by the dealer service dept and said they did a re-flash. I do have 5 Star tunes and did inform them of the gear swap when they customized my tow tune.

Forscan should be able to adjust for the gear ratio.

You don't need to adjust for speedometer to read correctly as it reads off the tone ring in the rear end and the front speed sensors, you do have to adjust if going bigger tires though.

Gears are around 250-300 for the set, master install kit with bearings and shims is around 150, so figure ~1000 to regear yourself. Obviously you can find deals and try and chisel that down a bit. I'd recommend Ron's machining if you want to do it yourself. https://www.ronsmachiningservice.net/new-category-142/

Re-gear at the dealer with gears, master rebuild kits and labor for both diff was $2800.
