Metalcloak lock-n-load vs Game changer

...Given the angle of the rears you lose about 20% vs front straight travel...

That is a good point, which I had not considered when I made the post.

Thank you.

This made me curious, so I approximated the dimensions by using an assumed 45 degree angle, which is probably a bit slacker than the actual angle of the shocks, but does illustrate the point you are making about the angles.

Then I realized I could easily go out and measure the resting angle of the rear shocks on my Jeep. I measured 63.8 degrees, so I made a second illustration that approximates the dimensions by using an assumed 64 degree angle.

Thanks again for mentioning the need to acknowledge the angle.

FYI per AnnDee's data, the length of shock at full metal-metal stock (non XR) bump is 17".

It looks like that figure is referenced from a thread where @Trill was raising the axles, without a spring in place, until the upper and lower spring mounts were pressed against each other.

This is really just a close enough number... almost all Jeeps are +/- 1"

Here's what I've been using:

A = Suspension Height (actually vertical distance to top of shock)
B = 11"
C = Shock Length

The reason I considered my post an approximation is that the angle of the hypotenuse or the length of the "B" leg of the triangle varies as the axle complies with the arc of the Control arms.

Good point... Doing some quick math (and using Metalcloak's standard arm lengths) A fully drooped stock Rubicon moves the axle forward less than 1/2". Obviously more droop would make this worse. Strangely, even though the pinion angle change is bad for the drivetrain (it will point further down with more droop due to the shorter upper arm lengths) this rotates the stock shock brackets up allowing for slightly more droop than if the pinion stayed consistent. It's not enough to counter the axle moving, but technically exists.

72.5" wide axles and 3.5" of backspace would really spice things up.

Hey!

Corious.. why choose 3.5" of backspace with 72.5" axles? and not, let's say 4.5" ? I am just curious..

Good catch! Thanks for bringing that to light! I actually just went back and changed that sentence from 3.5" to 4.5" of backspace. That's what I get for typing a few words at a time in between the buckets of material I'm feeding into a trommel. That post you quoted probably took me over an hour to finish. ?

The point I had intended was that 3.5" of backspace is necessary to push the limits of total suspension travel with the factory 68.5" wide Rubicon axles. Downside, of course, is the extreme scrub radius. The best setup, in my opinion is 72.5" (or there abouts) axles and 4.5" backspace. That allows plenty of large tire stuffing clearance, while keeping scrub radius at a more moderate level.

Ohh ok.. you had me concerned for a second there.. LOL...

I'm concerned for myself all the time, so I can spare that second. ?

Determine the lift height you desire for your vehicle. Different kits offer varying degrees of lift, allowing you to choose the one that suits your needs. However, keep in mind that extreme lifts can affect the vehicle's handling and may require additional modifications.

I searched but could not find much information or reviews on the lock-n-load lift kit. Is there a benefit to lock-n-load over Game changer or vice versa?

My off roading will be mainly rocks, Johnson Valley/ Cougar Buttes.

Lots of owners report great flex and road manners with Game Changer: one Redditor said “I have a 3.5 Game Changer on my JLU … flex is awesome, last year … there were several times where my rig was the only one that didn’t lift a tire.
