HERE is the article.
Yep it's an alternative. Has it's pluses and minuses.
great info. and if you want to build one of these with chevy power it will help ya out.
Where did you get that pic? That 2 1/2 is great. That would definately be fun.
Upside, cheaper than an NV4500
Downside, no adaptors available and the OD isn't that great IMO. 0.85:1 isn't really enough of an overdrive to make a meaningful difference.
My old SM465, 4.56's with 37's...2690 rpm @ 65 mph
3053A, 4.56's and 37's...2287 rpm @ 65 mph
NV4500, 4.56's and 37's...1961 rpm @ 65 mph
I did look into the Spicer before committing to rebuilding the NV4500 though.
The cruise rpm difference was the deciding factor for me, seeing as both were going to be a fair amount of work.
1 truck. 1 trailer for same truck. 1 extra set of frt hangers shackles and springs. then remove all rear parts. cut frame to length. install all other parts. and 1 set of 52" tires. bam you have 4x4 2.5 ton.
I stole some pics of a truck just like that 2.5 ton with trailer that just sold on ebay-- only difference was it didn't have a winch and it was on 12.50X20 XL's. Ya reckon there's two of them out there? I love the idea, and would like to build one with a cummins 5.9.
thats the one i just saw and was very tempted to go grab it. as i am close to there. just didnt have a drop deck lowboy semi to get it.
