what are the best brand if chromos for sierra? andwhere do i get them from?
thanks

[monley]

Lowrange.com is where you can get them...they sell rock assaul cv/axles...can't comment on quality tho

[suzi-fan-22]

yer i knew that but i seen some double tough cromos for the same price and made me wonder what is better quality

[Joshyboy26]

Im pretty sure the trail tough ones are better but dont quote me.

Actually the Spidertrax ones are the best you can get for sierras, but at $500USD, most people go for the cheaper rock assaults, and trail toughs.

Material, design, manufacturing process, post treating.....

Most people won't ( and don't) have an issue with the R/A's ot T/T CRMO gear, so paying double for seemingly no gain is not the chosen path for most sierra owners.

I honestly havent seen a chromo cv dead. ive seen a few axles twisted off though.

I will be running custom hytuff inner shafts with rock assaults to avoid this

I'm currently on my second set of chromos... My first set was a set of the Trail Tough's and they broke, so for my second set i ordered the rock assults from lowrange. Partly because they were 50% off at the time and combined with a strong Ozzy dollar meant they were pretty cheap...

They havn't been in for long and i havn't really given them a good workout yet, so i can't really comment on any differences... But if you can afford it, I would just spend the extra and invest in the Spidertrax ones. I'm pretty sure Gwagensteve is running the spidertrax ones and hasn't had any dramas yet...

What did you break RPM? The CV or the axle?

[rpmwrx]

The long side axle splines sheared off inside the airlocker. I was very lucky the airlocker was ok...

[monley]

Didn't steak_knife break break a r/a CV?

[suzi-fan-22]

I knew he broke a CroMo on 30's
I just don't know what brand

[tanshi]

nope he rung off an axle shaft
and by the looks of it in a similar place to all the others ive seen.
end of the spline on the diff end of the shaft.

31" treps as I recall. Fun guy to wheel with, shame he ran off and joined a commune...HIPPIE.

[Gwagensteve]

Just to clarify, regardless of brand, all US sourced cro-mo CV's are exactly the same, and as far as I know, they are manufactured by EMPI.

The difference between the manufacturers is all in the inner axles. Trail tough, for instance, have sold 5 different versions of the inner axle, with various changes in material and design.

I have, I think, the 4th gen inners, which were made by CTM, but the trolley tug runs the 1st gen inners, which others have broken. Michael's had no problem with his though.

I have fitted a pair of spidertrax cv's, but they haven't been wheeled. They were very nicely made axles for sure. I don't think spidertrax list them anymore though.
