well for the full time aburn lsd with 4/10 gears installed.... they want $1,142.62????? does that sound like a good deal?


any other ideas... also what kind of 4/10's should i get.. i drive this truck daily... and want awesome accleration but with good top end.. do you think 4.10's are the way to go... or are 3.73's better for what i want.

I have paid 1500.00 installed before. Check with Nelson Performance of TRT they might be cheaper. If you are close to them.

do it yourself.... all you need is patience and a good memory

[05chevyguy]

yeah but dont you have to measure backlash or something like that?

[txarkitekt]

There is a few more things in addition to the backlash...pinion depth, pinion bearing preload, and carrier bearing preload. Shims are used for correct spacing, but each rear end is slightly different, so you have to use a micrometer or dial indicator to get specific depths. It's a pretty intense install unless you know exactly what to do...

That's maybe $75 in tools, cheap.

I don't think the 4.10s are going to help you any with topend.. I might be wrong but the higher the gear, the more you lose topend

You want to be at the top of the RPM in your chosen gear when you trap.

Do you even know what kind of times you'd pull to run a 130mph trap? Many 12 sec rides only trap mid 100 teens.

Then how would a 4.10:1 limit you to 80mph? This does not make sense.

The 130mph was with a 6000rpm limit, 30" tires.
