If the drivetrain is all original, then its not a synchro. As already mentioned, every 1980 4wd got a 205. Auto hubs didn't come out till 81 IIRC, and that is when the synchro 205 came out. Take a pic of the back aluminum cover. Make sure it's clean so we can see lol..
I almost bought a 92 Blazer that was SAS'd, had a Vortec 350, but was auto 4L80. He took the entire dash, wiring, ECM, engine and trans n swapped it in. Dash n door panels didn't match, but looking back now wouldn't be a big deal.
i've never notice that!! But i'd say it's OK. Other than lack of crossmembers, the spring hanger is still there, and the spring is still bolted to the axle, so, it aint going anywhere.
Let us know how they work. According to Skyjacker should give total of 4" or so. Be interesting to see how they work with the weight of the big block/3/4 ton burb!!!
The drivetrain in these trucks are shifted to the pass side, wanna say couple inches but not 100%. They did this to tuck everything in closer for better fitment for the front diff being so close to the engine and high in the frame.
Looking good! Actually had nice weather and was out working on mine. Swapping the 44 out for a 60, and the 44 will be going in the Yukon. Gonna be getting a complete SAS hopefully soon for my black 99. Getting tired of looking at em and not able to work on em. Gonna have to check out the plasma...
I thought this too, and in some cases it will make a difference. But I had a 4runner with 20' wheels, and 245/60 mall terrains. When I first saw it I thought it was gonna ride like crap. It actually rode pretty nice. Now if you have like 2" of rubber between the road and wheel, then might notice...
I'm pretty sure springs are all the same size. Length and width. Even the squares had the same size, just 52" or 56" long. 3/4 or 1 ton will have more springs, and each leaf will be thicker.
