I fully agree with RBryan's above statement. There is a thread I started a while back (Any Damage From Driving on Rough Roads?) in which there was quite a good discussion on various types of damage that Escape owners have incurred while travelling on rough roads. It is good to have adequate ground clearance such that you are not bottoming out on ruts and rocks, however, at some point the ability of the Escape trailer shell and its contents to withstand the rough roads becomes the limiting factor rather than the clearance between the road and the trailer.

Thanks Dave. I'm not planning any technical 4X jeep trails but like options and not sure where I'll be going. Would like to do BLM lands etc. and a friend has a cattle ranch, land locked, so 5 miles of dirt roads thru hills to get to. I'll check that thread. Thanks for the link

Jeff

So what did that trailer have? What arm angle, and did it have a spacer?

"A 22.5 degree lift" presumably means a suspension arm start angle of 22.5 degrees down. That suggests that the stock angle is less (so the trailer sits lower, probably 10 degrees), and that the 22.5 degree option is the "high lift axle". There are two more extreme angles (32 and 45 degrees), but that's generally not advisable for ride quality.

Dexter Axle's Axle Measurement sheet explains the idea of a "start angle" (as well as showing the low profile and high profile brackets).

The Dexter Axle catalog section for 2300 - 4000 pound capacity shows the Torflex model used by Escape (the #10), with the available angles, heights, and amount of travel when load is added.

Typical trailer suspensions - including Torflex - have very short travel. Adding the maximum allowed 3500 pound load to an unloaded 22.5 degree Torflex #10 only compresses it 2.3 inches, so adding several hundred pounds to the weight of the empty trailer to the weight of the loaded trailer might make half an inch of difference.

That's the point of this topic - to understand what "high lift axle" actually means. Until we know what it is, we don't know if you even can add spacers (a "lift kit") to it.

When we know what we're dealing with, it will be easier to interpret the responses from existing owners.

Of course, everyone will have encountered different conditions. What works fine for one owner may not for another, and vice versa. Some people may camp in entirely unserviced places with smooth and easy access, while others may use full-serviced campsites that almost need off-road vehicles to get into.

The spacer is apparently about 1.5".

The height difference at full load between (for example, guessing what might be appropriate) 10 degrees down and 22.5 degrees down is 1.3 inches.

I think Brian-BP mentioned this in a previous post, but a hi-lift axle doesn't change the axle, it only lifts the body. The tube for the axle is at the same distance from the tube to the ground. The only way to lift everything is to change the down angle on the axle.

I had a 45 degree down axle put on my Scamp and it lifted everything. Not just the body.

As Donna explained, a spacer (which apparently is currently available from Escape) lifts the frame and body leaving the axle tube at the same height, so if you're looking for under-centre clearance for rocks this is not the complete fix (although tanks and stabilizers are lifted).

Jeff said Dennis suggested that there is an arm angle choice. A further down arm angle does lift everything, as Donna did with her Scamp.

Either one raises the tongue and bumper, so if the clearance concern is dragging through dips, then either lift method will help.

Now, which one does or did one get with the "high lift axle" option? What is now standard equipment in a 21-foot?

For what it is worth , our original 2010 5.0 came with a lift kit. It consisted of a section of 1.5" square tube between the axle and the frame. This piece was welded in by people who build the Escape frames (Level Fabricators of Chilliwack) at the time the frame was built. It also came with larger tires than stock as of 2010. 2 years later we acquired a new vehicle that did not require the lift and we had it removed by Level Fabricators. Gerri found the lift made it very awkward for her to get into the trailer. A double step would have helped. When I was contemplating lowering the trailer Reace explained that I could remove the piece of tubing or I could purchase a new axle with a different down angle as Brian has explained.

Fast forward to this spring. The new owner off our 5.0 was interested in reinstalling the lift. I did some research and found that Dexter makes a lift kit for the #10 axle that supposedly raises the trailer 2 5/8". That's a lot. I asked Reace about the Dexter kit and he was not aware of it but suggested he was going to order one to test it. For those who are interested the kit from Dexter does two axles, so if you have a 17' er you can sell half of the kit to someone else.



Quantity:



#10 Torflex Lift Kit (K71-707-02)
Price: $170.94


#10 Torflex Lift Kit K71-707-02

Tandem #10 Torflex Lift Kit (K71-707-02)
The lift kit will raise the units frame height 2 5/8".
This kit will only work on a #10 Torflex axle that has been mounted using the side mounting axle system option. Will not work on top mounted Torflex axles.
The kit has enough parts to do a Tandem axle unit.To determine the bracket hole dimensions that the kit has click here.
Caution: This lift kit can't be used with 3" tall brackets.
(4) 003-377-02 Frame Spacer #10 (2 5/8" Tall)
(24) 005-111-00 Washer
(16) 006-126-00 5/8"-18 Hex Lock Nut
(16) 007-177-00 5/8"-18 Screw Hex Cap Bolt 1.50" Long



Hope this helps, Mark

PS the Dexter site has an installation guide for this kit that shows one installed.

Thanks Mark. That adds another interesting wrinkle: a spacer which is welded to the frame (the more obvious approach would be to bolt to the plates Escape uses as brackets, as the Dexter kit does). If you happen to know... in the raised configuration was the axle welded to the spacer? With a spacer only 1.5" wide, that seems like the only choice. The conventional approach would be to bolt it to the spacer with vertical bolts (which Dexter calls top-mounting), but the spacer would need to be wider; without the spacer, the standard Escape method is side-mounting (horizontal bolts through the plates which Escape has welded to the frame).

You inspired me to search that out:
Torflex Lift Kit instructions
This illustrates the Dexter kit, and the general idea of any bolt-in spacer, quite well.

I note, with a mix of disappointment and amusement, that the instructions provide a bolt tightening spec... then show the use of an air impact wrench without a torque limiting bar.
