ok i have a big lifted up 83 k5 blazer and im looking for some new axles, i have destroyed mine haha they were stock axles i believe, but with 4.10 gearing. but anyway i got 35 inch tires on it. i believe i have a 202 transfer case caseor 208 cant remember. i just need to know where would be best to find some axles id like to go a little bigger with maybe 8 lug. and change gearing to 4.56 or drop it to 3.73 or somethingwhat are your guy‘s takes on all this.?
Legends, whole crimpped oats, total control, u-7, elecrtolytes, hay
For my personal 5 horses 100 lbs of fresh ground local grain. 50 lbs dog food (that's not for the horses) 50 lbs chicken feed (neither is that) saddles, bridles, halters, tool box, garbage can. Oh yeah, I almost forgot-a 10 ft long garage door. (?)
Well mine is a tack/feed room. 3 bags of oats. 3 bags of sweet feed. 3 bags of beet pulp. 1 bag of alffelfa cubes. 4 bags of treats (the little bags) and 5 saddles and 13 bridles. plus about 20 halters. salt licks. supplements. and some other stuff for 3 horses :)
Check out yukon or superior axle. These seem to be the newest big names out right now. Good luck and love them k5s.
Any of the 73-87 truck axles will work, some with some more work than others. Believe 1 tons had different perches on the axles. Your two easy options for increased strength in the rear are the 14SF (semi-floater) and 14FF (full floater). The 14FF is as near bulletproof as you can get, but it weighs about 500lbs. The 14SF is very strong, it's axles, gears, and bearings are larger than the stock 10 bolts you blew up, and it is very unlikely you will break one. Also much lighter than the 14FF. 3.73, 4.10, and 4.56 are the three most common ratios for these. The 14FF is 8 lug only. The 14SF is both 8 lug and 6 lug. Outside of 1987 ('91 for suburban, crew cabs) the axles won't bolt in, but are the same thing. You'll need to move the perches. For the front you have very few options. The axle housing is the same 1/2 and 3/4 ton, the difference is only in the hub area. The other option is the Dana 60 out of the Chevy 1 tons. These are quite rare, and $900 for one is a decent deal. 8 lug only, so you'd be getting new wheels. If your rear axle was a gov-lock, they are more prone to failure with abuse than the open rear diffs. With that size tires and hard use, even an open diff 10 bolt is going to be stressed.
