Regear? Or look at another platform?

[03envoy]

After getting my 265-70-17's put on I was to excited to notice the substantial lack of power with my 3.42's. I was using my landscaping trailer and had about 3,000lbs in it and I struggled. Even without the trailer it's rough getting up to speed. Is swapping to 4.10's worth it? Or should I be looking for something in the gmt800 range....? I'm leaning toward a 2500 but if I can save some money and make it work without spending to much id like too. What's your thoughts?

Regear, your truck has all the power it needs, you just have to help it get to the ground. Plus it's cheaper than buying a new truck.

Gears make a pretty dramatic difference. Regear it and call it a day.

4.56

4.56

Why

[HARDTRAILZ]

Due to pulling 3000 lbs plus another 500-1000 lbs for trailer itself. 4.10 is a stock gearing and with the bigger 32 inch tires and towing...lower than stock is easily preferable.

I would still like 4.56.

[ErikSS]

Did I read somewhere that it is actually less expensive to go 4.56 than 4.10?

[HARDTRAILZ]

I really don't see how unless you do the gear setups yourself.

[ErikSS]

What I remember is that the front is getting stupid expensive for 4.10's... And there is no cost difference in the rear, you just choose 4.10 or 4.56. So the front is the only difference. I dunno, seems like MikeKey said something. I should just ask him.

Of coarse, this is assuming someone is choosing to change front and rear gears anyway.

[HARDTRAILZ]

I bought 4.10 to avoid the $500 in setup costs... No way to avoid that fee with 4.56 but you can buy front and rear with 4.10.

Fronts w 4.10s were just posted on here for about 300...some place with a bunch of them.

Figure under 1000 for 4.10 completes with no setup or 4.56 plus install kits and setups and you are there and if you have a standard WB I6 you have to buy a rear axle. Easily over $1000, likely $1500.

[mikekey]

$500 setup is if you can't do it yourself. And even then, that seems extremely steep.

I bought my front 4.10 for $250 off a forum member and then sold it to Chris for $220, they're pretty reasonable.

Getting a 4.10 axle in 8.6 is expensive according to car-part and if you want an SS rear end that's $1000 in itself most of the time. I have seen some really good prices though in a few places, patience probably helps if replacing the rear axle at a reasonable cost. Comes down to how good of a price/deal hunter you are.

It is cheaper to buy the 8.6 in 3.42 and swap in 4.56 and rear-gear the front IMO than to buy a 4.10 rear axle for $800 and then another $300 for the front diff (still $1100) and later decide you want 4.56.

If you can set it up yourself, then I honestly think 4.56 could be done for cheaper than getting a 4.10 axle. Gearing isn't that difficult if you can handle setting the backlash. But you can F*** it up bad if you don't have a clue.

Unless you just want to upgrade your standard axle with 4.10's. That's probably cheapest. I dunno. I think I'm rambling now. Been low on sleep.

Just getting your idea on 456's. I already have the 4.56 gears to do my change just waiting for a call from a friends shop to get them done, but I have been second guessing thinking 4:10. My goal is to go 35's but it may take some time do to the cost of some unexpected repairs. So with the H3 wheels 285/75 are it.

This is one site I was looking at with their tire/gear chart http://www.superlift.com/library/gears.asp

With the Yukon gears:

• Rear gears-$260
• Pinion install kit- $93
• Non Slip-$435
• Front gears-$198
• I'm still trying to piece together an install kit for the front. The Yukon GM 7.2 IFS kit is $279
• A friends setting up my rear axle for $200 (he has a lift and heated shop)
• I have a spare front differential so I'll be setting up the front myself and using his shop to install it?

Just got mine here. Said he had 6 more 4.10's on the shelf. $265 otd. Said he could ship too.

[HARDTRAILZ]

$500 SS rear are fairly common around here. I got under $1000 in 4.10 swap including locker and carrier n such. I did shop for long time to get what I wanted at good prices but $1000 buys SS front and rear fairly often from what I see.

$500 for front and rear diff setup is cheap not steep actually. I regularly see 250-500 per setup. Having setup a couple myself now...I would definitely charge that in labor. Its not difficult per se but is tedious and takes some special tools and skill.

[03envoy]

That's the easier choice for me but then again I worry about other problems that a normal voy isn't use to taking you know? I love the truck but I don't want to put a couple grand in and have something else fail. Not sure what to do.

Honestly...if I were you, I would buy a 3/4 ton.

[ErikSS]

What about putting stock tires back on while you save some money?

[03envoy]

Funny you say that my BFG's are sitting in the garage and the voy is on stock trailblazer 16's lmao

I'm leaning toward that route or buying a 7.3l f350..... Mainly for gas mileage (diesel) and longevity...
My buddy that I work with is picking up a 5.9 cummins for the same work. While my other buddy in construction has a 6.4 powerstroke... Then there's me...lol The worst part is deciding if I go back to stock for the summer and sell my lift and wheel spacers.... That will be dreadful.
