Curious if there's a way to raise the bump stops to prevent rubbing with 32's. I had a rat chew through the transmission temp sensor wires leaving me with no suspension, and had to borrow a friends car to get parts and don't to risk any random events like that leaving me stranded. I've seen a video where someone added their own airlines and cut into the factory air system to manually inflate/deflate the bags, but with my lack of air experience (wonder how I'm alive!) is pointing me to a mechanical solution. Also wondering if the raised bump stops affect off-road articulation?

On another note, would the GAP ID tool allow me to bypass codes and or limp mode? I want to make this as trail fixable as possible, without spending too much money. I've seen the GAP tool on lucky8 for about ~$550, is there any other place that has it for less? There is 2 LR3's in the family and ideally having the 2 car option would be nice, is there a way to jailbreak/modify it to allow it to access a second vehicle? or am I messing with too many things for my own good? Any ideas or advice/general advice I'd love to hear.

 

The bump stops are located inside the shocks on these, so you aren’t changing those outright. A common mod is to add 2” spacers in the strut towers (effectively a body lift) and some limiting straps —look up the “SYA kit”. I think it means “save your a**”. There may be a location on the frame you could add an aftermarket bump stop, I’ve never looked myself nor read of it being done.

Larger bump stops do impact your articulation. They limit up travel.

You can add a 2nd VIN to the GAP tool for $50 or so. Look on the GAP website. If you want a cheapo tool so there is one in each car, get an Autel AP200 (white one). It does a lot that the GAP can do, but not everything.

 

I love the acronym, and it seems like that is a good alternative to manually raising the air bags. I noticed it reduces/eliminates access height, which means no more airport or garage parking for me! but anyways I'm going to look into the Autel, as currently I have a $30 AutoZone code reader.

Has anyone driven with the spacers? I have the 2.5 inch lift kit and usually don't drive with them on for gas and stability reasons, does it behave similarly/how does it drive? I lost the D2 when a friend flipped it so stability is a big one for me.

 

Spacers are are pretty much a "real" lift kit when installed with sensors recalibrated. Sensor rods leave you stranded, especially if you end up on bump stops since the rods push the sensors out of range and the system will 100% fault out - unless you jack up the front and rear to get the sensors back in range so the system can operate. In either case, the GAP tool can recalibrate the heights you want and the rods can be tossed. You will have some reduced stability but not really any different than you have now since you said you have the 2.5" rods, so you know how it handles with those. Either way, you MUST get an alignment after making all these changes. In fact you are kinda messing with the truck if you are taking your lift rods on and off, it should be property aligned and set to the height you want. Or for that matter, ALL suspension bolts should be loosened, height set, truck settled then bolts torqued down - all to prevent bushing twist and failure.

 

I've had the truck run on the bump stops at least 2 dozen times for about 300ish miles with 32's from random faults and some electrical issues all with so far, all with no issues with sensor ranges. I travel often to and from long distances with a roof top tent, so I like to keep the lift rods out for fuel and stability. When I go on trails (about 1-2 times a month) I put them on for the day/weekend. I don't have access to a cheap shop that can do alignments near me, but when I go home, I usually get alignments (about 6ish months). How high/low can the GAP tool make the suspension? can I override limp mode? another thing a bit off topic, is there an official repair manual for the car (something like the RAVE for D2s)?

 

With the GAP tool, you don't need the rods. You can go up as far as the EAS will let you.

 

Then you were not on bump stops, probably just "suspension lowered" which is basically access height. It is well known if you drop too far and have sensor extension rods installed, the sensors go our of range. And that SUCKS if you are on the trail and are not aware of the issue the suspension rods cause.

Not sure what you mean by override limp mode? With the suspension or overall truck? The GAP can certainly clear codes and you can, in fact, force the suspension to air up manual strut by strut. I do this when camping, I use "guided calibration" which lets one adjust each corner. But I also found out that guided calibration ignore faults and will, for all intents, "force" the compressor to run. There is a RAVE workshop for the LR3. I don't have a good link for it, might be on the forums somewhere. But it should not be too hard to find a copy. Maybe even a simple Google search can bring it up.

I will say this though, if your truck is maintained you should never have an issue on the trail. I take my truck out into some sketchy situations and overland thousands of miles cross county. I only had an issue once with a dying compressor, which I knew before I left. But I used the GAP to cheat my way home and keep the truck aired up. Other than that, I dont get random faults or any issues mudding, climbing or jumping the thing.

 

Yeah I know its a rare case, and I tend to follow "prepare for the worst, hope for the best". I meant like overriding the suspension, thank you for the answers! I'm guessing it was (Correct me if I'm wrong)it was on the bump stops as I the front left speed sensor wire went out, I had 6 people in the car, and gear on top and a hitch storage rack making the vehicle weigh a good 900ish pounds extra.. So far this truck has been fairly reliable but after a rat chewed through a temp wire making me miss a trip I'd like to have the ability to.

 

I have recently acquired an 06 RRS and yes I did install the 2.5 Proud Rhino lift rods, and when I get time I will finish installing the SYA kit. I like the idea of the spacer to act as a bump stop, and with the straps I don't think I'll have to worry about over-extending the CV's.
