    Wow, great pics and writeup Chris! :dblthumb: Chris is in Harlan all weekend continuing his never lift tour so he may not see this. We try to offer our best pricing via the website, we include free shipping as well and that's pretty significant with such heavy parts. With Memorial Day...

    gm dana 60 ??

    Thanks for the shoutout. We do pride ourselves on being the best when it comes to quality. However, we don't offer a D60 spool at this time. The Dana 60 is already fairly limited when it comes to pinion size and R&P strength these days. The Yukon spool should be fine. If/when you ever want...

    Sold/Expired 300m & 4340 14 Bolt and Dana 60/70/80 floater shafts and flanges

    Bump, thanks for the orders Hardline! Since launching two years ago we have put rock bouncers on the podium, we've had racers in KOH, and even got a set of 4340 shafts behind a 900hp big block bouncer :****: Here's a picture of some 40 spline 300m gun drilled shafts we did for a customer out...

    Rock bouncer front axle beef???

    Rock bouncer front axle beef???

    For 500hp and 44s or 43 stickies you're honestly fine with a set of quality 35 spline shafts especially in a front axle. RCV or CTM would be my first choice. Once you get to 600hp or more and drive like Jwhit55 then you need to start thinking about upgrading. 40 spline is the sweet spot for...

    New Product feedback

    Re: Re: Re: New Product feedback I got nothing bad to say about WFO as a company but I have held one of those yokes in my hands and I did not think it would last very long under a serious rock rig. It looked like a cheap cast piece to me. U-bolt yokes are getting harder to find in general...

    New Product feedback

    Looking for feedback on a new product we've developed. 14 bolt 1410 yoke, forged out of 4340, 180 degree u-joint cap retaining shoulder (as opposed to the nub), and compatible with standard u-bolts but will also accept chromo u-joint girdles that we will sell as an option for full 360 degree...
