Welded Diff vs. $1200 Diff | HiLow

  • Published: 25 December 2019
  • $1200 Limited Slip Differential vs a Free Welded Differential! Is saving the cash worth it? Let’s find out.

    Team Hi (James Pumphrey & Zach Jobe) and Team Low (Nolan Sykes & Aaron Parker) have installed coilovers, wheels, and big meaty tires in order to make their cars faster, but we’re not just building these 350zs to be race cars, we’re building them to be fun cars. And what’s more fun than doing some sweet drifties on the skid pad.

    To do that, we’re going to be swapping out our differentials... well Team Hi is. Nolan will be doing the time honored option of welding his.

    With an open differential, the power from your engine takes the path of least resistance to the wheels. That’s good for allowing the inside and outside wheels to spin at different speeds when taking a turn —which is the reason diffs were invented in the first place. But, if one wheel totally loses traction the open diff just keeps directing more power to it and that one wheel will keep spinning til kingdom come. This is what we call a one-tire fire.

    One way to limit that wheel from slipping is with a limited slip differential, or LSD. Team Hi bought a KAAZ SuperQ 2-way clutch-type Limited slip differential! 2 way means that the LSD engages the same amount during acceleration and deceleration. 2 way is generally the choice of drifters, because it keeps your lsd engaged pretty much all the time, which is good for skids.

    Another way to prevent that one tire fire slippage and not spend $1200, is to weld the spider gears together leaving your back wheels permanently locked together all the time. This is great in a straight lines and when drifting, but when you go around corners and the wheels need to go different speeds, the diff can’t do its job anymore and the wheels end up constantly scrubbing and breaking traction in small jumps. But sometimes breaking traction is exactly what you want :)

    I can't believe a sports car like a 350Z wouldn't come with some type of limited slip from the factory. Disappointing

          He said "Mines in a box". I highly doubt that creatures thing has ever been in a box, except for his buddie's buttbox. How did they find two such beastly looking guys? Is the ugliness supposed to draw in viewers or maybe just morbidly draw the eye like a corpse laying on the side of the road? Maybe it's like staring at an accident as you drive by. It must be. God that is a lot of ugly. You ever notice though that many TV people, like news anchors and such, are very weird looking? Like Jay Leno and Conan or that other red-eyed, rat-like albino freak. It's like people with weirdly shaped or oversized heads do well on TV, especially guys with unspeakably ugly faces. I wish I could invest in the guys in this video. They are going somewhere for sure!

                          I've had both on the same car. I prefer my 2 way. Just have to watch out sometimes decelerating too quick the rear end will lock up, If I were to buy a diff now I would go for a 1.5 way just because i'm not into drifting as much as I used to be. Problem with a welded on a daily is you definitely eat up your rear tires a lot faster and its very hard on your rear suspension or axles on every small turn. Also a welded diff your car wants to go forward, can be more prone to understeer if you don't want to break traction and drift around a corner.

                                        As there is no slip to be limited....it's eliminated !
                                        There are alot of Dailey driving that well irritate you after a few weeks of diving .

                                          It's so weird the US 350Z did not come with LSD in the first place. Did your 350Z have Brembos? Or did the Brembos automatically come with LSDs and vice versa?

                                            Wouldn't getting the original Nissan LSD from someone who got an aftermarket LSD be the cheapest option that is also viable for the track?

                                            I feel like you guys keep going through a lot of trouble to never properly finishing your videos. "Cheap vs expensive diff!" And then proceed not to actually test the diffs other than some burnouts. "Cheap vs expensive cover!" Proceeds to use shit plastidip that in no way represents how it would normally looks instead if waiting a day or two for the ones you initially ordered.

                                            Just please go the extra foot and actually finish your videos please. I know it would delay them a day or two, but it would make them so much better. Your cheap vs expensive comparisons aren't worth anything if there's consistently no conclusion

You basically doubled the engineering load on everything including the housing of which may flex more than usual and allow the pinion to ride off the ring.....if the case dont break first.
