Slammed Sierra Rear End Swap for the Upcoming LS Swap

It does take me longer than others

Absolutely

[@aag6499]

Awesome job Mr, TWA i just changed the pulley for the steering pump and so a new rack and pinion on my TA. And capped the oem cooler , but i installed an external steering cooler behind the plastic dam under the radiator. Hope i get to drive it next week

[@utahcountypicazospage5412]

This diff is better then the spring loaded diffs the block style for lock up is better for longevity and before you worry about differential transmission needs to be built first before anything the 4L60 Is super weak and doesn’t like anything over 6000 rpm shifts so if you plan on a camshaft or stall converter the transmission needs building or don’t shift past 5900

[@TWAMotorsports]

Yeah I know the transmission will be on borrowed time

I would be interested in hearing about what you do about correcting the speedometer after tire and or gear swaps. I put 20s on my tahoe and the speedo is off about 5 mph.

That will be done with hp tuners when the motor goes in.

Not sure

That looks awesome Travis! I did this to my 04 rear with spray paint products and so far so good. U want to use por15 on my Duramax chassis and frame though. I thought of buying the TA diff cover for my Trans Am to preserve that rear end lol. As always enjoy the videos!

Nice video bro what year was that truck you took rear ended out. And what were those numbers again that you look in glove box

[@TWAMotorsports]

Think it was a 2001

[@jjohnson479]

You could have put the gear oil in before you put the cover on, since you had it opening facing up. That way when your sealant dries, all you have to do is put the rear in back in. This will also test whether your front seal is good or not.

[@TWAMotorsports]

I could have. I put the gear oil in a few days later

[@Trebor-gw8lt]

In the 10 bolts with the fill plug high up on the pinion snout like this one, I put in ~2.5qts of lube.

[@TWAMotorsports]

Good info. Thank you

[@ZackNakazora1]

are we doing warm over mods first or v8 in truck then we warm it over? G80 isnt bad for a street truck. i think the other is the G86 is the LSD which I think is a helical gear style? Im still a fan of 4.8 pistons 706 heads and a hot truck v2 cam with TBSS intake. pick your headers and some side exit exhaust

[@TWAMotorsports]

Several things to do honestly. Just a cam and headers for now.

G86 is a Eaton clutch plate LSD.

Perfect timing on this video. Was thinking about doing one of those covers for my LT1 Camaro. Probably worth the $150 for a little bit of protection on these rather weak rear ends, no?

[@TWAMotorsports]

Absolutely worth it for added strength

[@emilenorton7347]

What added Strength it just holds fluid if you want strength and protection better gears and axles will get you right a diff cover WILL NOT this guy is delusional it’s still a GM stock rear end.

[@brandon.buchanan81]

Travis, did you have the computer flashed for the different gear ratio? I assume you used your HP Tuners to make the change. Talked to my guy that does tunes and he said its a simple change in the computer. I was just wondering if the trans felt ok before you flashed it. I bought a G80 rear end that I am going to go through before I do the swap on my sons truck

[@TWAMotorsports]

Yes I did make those changes with hp tuners but before changing it all felt good.

[@brandon.buchanan81]

I was just wondering if it would be ok to drive about 35 miles or so to get it flashed or if I would need to trailer it. Thats why I asked if the trans was ok if you drove it before the reflash @@TWAMotorsports

[@TWAMotorsports]

@brandon.buchanan81 you can drive it

[@brians.8554]

I know this video is old but Im hoping you get a chance to respond , did you have to get any type of tune to be able to run this swap?

No but shift points and speedo will be off if not.

Should work

[@thundermountainatv]

Do you have a list of possible donor disc brake rear ends that work on the 94 and older trucks? and how did you determine the gear ratio on the disc brake rear end?

[@TWAMotorsports]

I don't. Have to open the case to be sure on ratio unless original to the vehicle. Rpo codes in glove box should tell gear ratio if it hasn't been messed with.

Travis, is there a benefit to do the rear end swap on the V6 if i don't want to do the v8 swap? Like I said on your last video I just got an 03 silverado v6 but I've noticed it has rear disk brakes. I thought only the 4x4 models had rear disk. Am I wrong? The thing sits up way to high and I'm assuming the previous owners did a complete 4x4 suspension swap.

[@Mrstroubleloves]

Its only a 2wd. Im aiming on doing an SS clone thats why i got the 2003.
