    If the labor is 1k both axles I don't believe the gear sets are more than $500 each for the aam parts are they?

    Gotta get the master install kits as well, the gear and pinion sets are usually around $400 depending on brand. Then you need the fluids as well. It all adds up in the end.

    You need bearing and shim (installation) kits. You're looking at well over $1k in parts alone.

    Ok thanks guys...i always figured it'd be around 1500/axle so it looks like that's still in the ballpark.

    I remember way back getting 3.73 gears in an 86 mustang 5.0/5 speed. I think the entire job was $500 or something like that. Man those 73s made 1st gear like a creeper gear....it'd blow the tires off big time......if you really got after it (LOL)

    That is a great price man. How do you like the 88s? I think you gave one update since install. Are you still liking them? Worth the cost?

    Absolutely the best modification i have ever done to a vehicle in my life. I love the 4.88’s. A part if me wishes i went to 5.13’s with my 35’s but the 4.88’s make it a completely different truck in a great way.

    Cool man...thanks for the feedback. I think I'd go 4.56s with my stock tires... If i could get them for the price you paid id be tempted

    What did you do with your speedo...? Can it be corrected somehow?

    Man I actually think mine tows decent with 373s and 35s and I pull about 15k in NH... a hell of a lot better than our v10s did or the ford 6.2s all on stock tires...I would like to swap to 456 eventually but probably won’t bother

    Going from stock 33’s to 37’s will play hell on your torque converter. Do the gear swap
