    Who's using the Poly Performance rear chromo axle? Any problems with the install? Overall opinion of them?

    I'll be moving up to 38's soon with longfields in the front and want a stronger rear axle also.

    Thanks

    Install is VERY easy -- It's just an axle change. You do need new studs. I re-used my old ones.

    IMO, while I think the chromo rears are nice insurance, I've never broken a stock FJ40 rear axle shaft or the minitruck ones I have installed now....

    I've busted LOTS of other stuff tho, including a short side Poly Performance Gen2 front inner axle...cryo'd pinions, t-case shafts, welded Longs, and more....just never a rear shaft....

    I have broken stock rear shafts and seen others break them as well. On 38's..

    They are a good idea IMHO
