View Full Version : XJ/MJ rock slider questions

07-07-2011, 02:33 PM
I'm going to be building a set of sliders for an MJ soon. After doing some research I discovered that most designs incorporate a bar (generally angle iron) which rests against the pinch weld and bolts through the pinch weld to another strip of steel thereby sandwiching the weld itself.

My questions are;

Do you guys running sliders have the afformentioned pinch weld dealy?

If so, did you build the sliders yourself and do you have any design tips for me?

If not, have you had any issues with your pinch weld sepparating from the shear forces created against the cheesy sub-frame by the sliders?

Thanks in advance for the help [cheers]

Yea u should incorperate the pinch weld by doing so it disperses the shovk load through the entire body not just the unibody frame rails.

I run aj's superrails, with the pinch weld mounting. I dont think they would be that strong without the extra mounting points. I saw a cross section picture of the "framerail" on another jeep site, it scared me enought to run weld on framerail stiffeners even before I bolted on the rock sliders http://www.hdoffroadengineering.com/

I got tboned slow speed by another jerk off in an xj hit my directly in the rock rail and lr tire, hard enough to bend the axle, and nothing else budged.... I have also winched my heep off its side and onto all fours using them as an anchor. So yes opt for pinch weld mounts
