View Full Version : Revolvers, yes I already searched???
With a stock drivetrain Grand Wag with a four inch lift, will I need to notch the crossmember and put longer brake lines in the front? Need definate answers.

Revolvers are supposed to give you a max drop of 9-10" over your current set up and will also give you close to an inch of lift.... that puts you up about 5"s over stock and now the axle will also be dropping close to 10"s.
Longer break lines will be needed for sure.
Whether or not you acutally get 9-10"s more drop will depend in part on the travel limited by your shocks.
Jack up the frame, run a straight edge down the underside of your front driveline from the upper joint to the lower joint and then drop the lower end another 10-11 inches and see if you lost clearance at the cross member... you might be ok since you are not SOA.
Disconnect the lower end of one shock and see if it will even drop another 10-11"s from where it hangs... probably not, but from where it stops you will know, roughly, how much the revolvers will actually drop and you can recheck the drive line drop and clearance using that information.

You will need a high angle front CV shaft.... new shocks and prolly reroute your exhaust unless you have duals already...
X-member may need to notched.. wont know untill you get the high angle CV in there and test it...
Mine didn't need notching...
That blows!
I thougth for 150 I could get away with more droop and articualtion, but as it turns out it requires way more dough than you expect.

I take it you didnt see my other post on the gen board with all the pics... ;)
This is not all the flex either...

Oh I did. Its awesome!!!!
I am in ther process of doing a new y-pipe, old one is shot. Need to buy all new front end parts and have aligned. Just too much $$$$ right now. Thought I could get away with just revolvers and not all the other associated crap that goes with it (high angle CV mainly).

Explorer ProComp ES3000 extended travel shocks (Summit has 'em) will give you 15" of shock travel and measure 21"/36"... gotta be sure they don't bind up in the mounts with all the drop on those revolvers though.
Still working out my system and was planning to keep my stock 3/4 ton springs until Todd started talking about all the flex in his 63" rear 3/4ton Suburban springs... gives me more to figure on as I wanted the carrying capacity and didn't know I could have the rear flex also.
Todd,
What do you have your front axle shimmed at or do you?

D60 is not shimmed at all...

Here's some shots of my jeep with the front running revolvers.. Probably could have got some more but I was about to make contact in the rear...
I have a 1310 High Angle LONG SPLINE front shaft
SUPER long SS front brakes
Homemade crossmember for clearence
and SOA...
IN this picture you can see that my revolver is not close to fully opening... I also need a bumpstop on the other side since my springs are so flat they are compressing and hitting the Zerk Grease fitting on the revolver

Lots of droop with my factory flat springs in the back...

Donovan...
Dont try to save the grease zerk... it's futile...
take it off and use a flushmount and grease it with a needle point... ;)

well im almost done w/ my suspension mods, and im running revolvers front and rear, high angle front d-shaft and ridiculously long brake lines. i also just picked up a set of those procomp 15" travel shocks, hopefully they’ll be long enough.
but ya theyre is a bunch of little crap that youll have to get. not sure about your x-member though. i just made a new one, but my old one had enough clearance.

I have seen them on soild small grease guns but not just the fitting. I have one that is ACTUALLY a needle for greasing sealed bearing applications but it's not really functional for these types... thanks guys...

The part I don't understand about revolvers is that they just allow the axle to drop, but there is almost no load on the tires touching the ground once the revolver starts opening, so any traction gains (IMO) would be tiny. Can someone please explain this to me?

Don: got my needle grease fitting at car quest. Cost like 3 bucks. I need one for my rear drive line.

Can someone please explain this to me?Somebody can probably explain it better, but don't think any traction improvement equates to being "tiny" if it exists at all. I used to be a rock climber in my youth (as in my physical body applied to a rock face... not my truck) and what I can tell you from scaling rock is that the slightest amount of friction you can apply across the most points possible overcomes what gravity would really like to do with you.
Being able to drop that wheel another 9-10 inches can make a big difference in being able to find a 3rd or 4th point to momemtarily balance and move to better footing and you can catch and pick up traction from binding up your sidewall also. Being locked at both ends won't overcome your inability to balance on two wheels and isn't going to neccessarily get that hanging wheel or two into the next crack as easily or as surely as if the friction was spread more evenly.
Hope that makes some kind of sense.
If you imagine crossing a fairly deep water bar on a logging road at an angle... without something like the revolver your suspension is going to be more rigid and your transition to the opposite side of the water bar is going to be much rougher if you plow into it rather then have your forward tire drop into the bar and begin to catch the opposite side while your trailing front tire just begins to drop into the bottom of the bar.... you're actually picking up traction on the leading side before the trailing side loses it.

Donovan did that flex pict and he has no lockers, and he didnt spin at all. Without the revolvers he would have spun, and maybe had a tire off the ground. He also climbed some hills well because he was better able to keep all 4 tires on the ground. So if you dont have lockers, revolvers can aid more then you think.

Mikel,
I know what you're getting at, as the spring is no longer pressing the tire down once the revolvers come into play.
Nevertheless, there is the weight of the tire and the axle, which is not insubstantial. I just mounted my XML's on my D60 to move it around, and it feels every-bit of the 700lbs that it is. So that would provide at least a bit of traction, enough that, combined with the traction on the other-side, can probably move the truck rather than spin the wheels if the driver uses a feather-foot.

Leverage also comes into play. While the one side is being compressed, that spring is also acting as a fulcrum point, with the axle being a lever. So if one side is pressed up, the other is being forced down. So its not just the weight of the axle.
