Hello all,

I have a base 2019 Sierra 5.3 4x4 and bought the front / rear shocks and rear blocks of a AT4 owner who upgraded his suspension

Does anyone know if it's necessary to replace the CV axle when installing the 2" lift?

Thanks

The kit that is available from GM includes longer shafts.

It is not necessary to change out the CV's, and 99% of people lifting their base 4x4's or Z71's by 2" don't.  If you go above 3" and actually off road your truck, I would start looking into getting the CV's.  But again, for a 2" lift it is absolutely not necessary, there is nothing to gain.

Funny, i have a AT4 and just installed bilstein shocks front and rear and removed the life kit. I installed base sierra cv axles in the front. The length is the same but the housing part that goes into the diff is slightly smaller.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      The truck is a 1995 Chevrolet S10 Blazer, 4.3 VIN "W" engine. :cracks knuckles:   On a whim - because I needed a headache - this truck was for sale so I stopped to take a look. Doesn't run. Well, it does, but barely. Long crank, choppy idle, bad misfire(s), it REEKS of fuel. I can DO this..I'm thinking. Diamond in the rough. One owner until last year. A young guy is selling it, he bought it 6 months ago. It stranded him more than once, he's got a newborn. It was in the shop 10 days ago and he "thinks" they said it needs a new fuel injection system. He can't put any more money into it, needs it gone. I was thinking of upgrading my Macbook, which is a total want, not a need. For less than the price of a new laptop I can have fun for months. I'm taking this truck home.   Some parts, a wash, maybe a set of tires, and I can have a few months of fun and then turn it for beer money (or the next project).   Sure enough, there's a work order from a shop last week in the INCHES of paperwork on this truck dating back to when the first owner bought it. They put a new distributor in it, fuel injection work describes basically opening the plenum and putting it back together. He said he couldn't afford any more work so he had them button it up and that's when he put it up for sale.   I'm not well versed in 4.3. I did discover 1995 uses the 1992-1995 SCPI "Spider" injector which is riddled with issues from splitting lines, clogged or cracked poppet valves and plastic spider legs that crumble over time. Cool. I'll just order me a ne---. Oh, the auto parts store doesn't have it? Rock Auto doesn't have it. eBay? $$$$$$ for used. These are UNAVAILABLE period end of story unless you know "a guy" who's still got one in a box somewhere.   Can't upgrade to the '96-'04 injector, it's a different plenum, wiring/pinout and sensor config.   There are a few kinda "know a guy" -guy rebuild services for these injectors out there for about $350. Okay, Okay... I'd like to know if anyone has used them? Anyone got a lead on these crappy 92-95 spiders?   I also don't want to send MY spider to Narnia and back without knowing if that's truly the problem. I guess I'll need to pull apart the plenum and do some digging.   I was also thrown for a loop. This 1995 model year truck has an OBD-II connector. The interface is decidedly not OBD-II. I can read and reset trouble codes and view live data, but there's not a lot of data. Like misfire count and on what cylinder, that's not there. It's OBD-1.5.   Nothing is ever easy. Now it makes sense why this guy wanted to disappear this thing for cheap. I'm guessing the shop told him the injector is toast, the part is unobtainable and they're not going to sort sending the thing to a rebuild service, and the kid likely can't be without a working car for 3 weeks even if they'd facilitate that.   Experience with these early SCPI's? Stories? Things to check? Sympathy? (..Nah...)   This can sit until I sort it. But I haven't had a problem with a vehicle I couldn't easily solve in a long time.

      I have four that read by the dash 8 to 10% better than miles/pump calculations and I have one that is spot on.

      Typically it is the Torque Converter, I have a 2.7L Trail Boss and between 25-65 MPH at 1300-1500 rpms under light throttle it has a shudder which I almost consider and bobble or a gargle sound. They replaced my TC but it did not help any, others say it has fixed their issues. It has been back twice now with no fix after.
