Pretty sure keith cuts them down enough for a stock Panhard now.
Dunno, but this is from his site.

Thinking of the QT as a diff slider is really going down the wrong road. that rock you are sliding over should be under your right tire or left of the diff. Thats why the diffs are both off set to the right. Once you start sliding your diffs over rocks you face the fact that at some point you will end up stopping and sliding back and now that rock is on the rear u-joint or driveshaft.

I'm with you 100%... when you can see the rocks. The problem comes with chocolate chip cookie dough roads, and water. You can't always see what's under there. I do not aim to slid the diff off rocks, but sometimes it happens because you can't see the rocks.

keep your tires on the high spots accept the off camber position it puts you in and protect your drivetrain from damage...words to live by:D

Good point. Simply calling it a slider implies that you intend to use it in that manner. When driving, you shouldn't base your plan of attack on sliding over something. The goal should be to keep everything away from the rocks and plan a line to do that. IMHO, the slider diff guard is a crutch.

It's True!!!! I cut them down so you can use the stock panhard, it is a bit of a chore to put them on as you need to remove the entire factory cover. To be honest the best cover out there that is not a sewer cap is the Mantek weld on.

So why have *any* diff guard? ;)

Seriously, though, I keep my diffs clear of from rocks, but sometimes in long grass, water, mud (or from just a lapse of concentration or judgement), one comes up and bites me. Other things being equal, I'd like it to slide under rather than ********** up against an unforgiving surface.

I see rock sliders and bumpers the same way, btw - not as things to be actively used, but to protect the truck if I make a mistake.

I have the QT diff guards fitted to both front and back on my DII.

I think of their label as "sliders" not as something that I am going to intentionaly use to slide over an obstacle, rock or log, but rather a description of what they are capable of doing.

Having any design of diff guard is no replacement for driving the high points and keeping obstacles left of center. I can't imagine anyone with a QT approaching an obstacle and saying "ok, I have diff sliders so I'm gonna hit that with my diff and slide on over"

For me I look at its design capablitlities as extra insurance. If I slide off my chosen line, if a rock or log moves under me, if I'm in a water crossing and can't see everything on the bottom.... if something contacts either of my diffs I know the intended design capabilities of the diff guards will help.

You mean Mantec? LOL They don't seem to be on the web site.. So sewer cap it is! :elkgrin:

Yes, exactly. Usually I'm the smallest tired guy in the group, and usually somebody more experienced runs through first. Often water is "scouted" by the leader who knows the trail, and goes through first while the rest of us watch the depth and any obvious obstacles underneath. It all works out fine, except for when he passes over things on the bottom due to more clearance. Then I go through, and find all the things he didn't. Given this is usually the time I *don't* want to get stopped dead, I like having something under there that will help me keep moving, rather than stopping me dead.

I looked everywhere for the mantec contour ones. I couldn't find them anywhere.

That's a good point. Maybe it's salt which makes the difference. I just saw a lot of corrosion testing with ZDC plated bolts, and they still rust. But that's under heavy attack from salt spray. Also on my own cars up here, I know they still rust, due to the salt. In fact, I think my rear diff guard may already have some rust on it, after only one winter.

That makes sense. I don't think mine have ever seen road salt.

The QT does integrate a pinion skid, but does not seem to go far back enough to protect the ujoint.

I will look into those a little more.

I found the QT diff guard to cause leaks where the third member bolts on. I think it is due to the QT flexing when hit in the front transfering the energy to the 3rd where the rear mounting points are located.

This happened on my truck and one other on which I have first hand information.
