Daystar 1.5 rear install - bumpstop clearance?

So I was looking at the installation instructions for the Daystar rear 1.5 install, and was wondering about the clearance between the axle and the bumpstop after the install (I'm talking about the conical bumpstop inside the spring).

With the 1.5 spacer that comes in the 2.5/1.5 kit, or by itself for the 4runner (KT09118BK), from what I can tell the spacer is installed over the bumpstop, in the following order: frame > bumpstop > spacer > coil. What this means is that there is now an additional 1.5" of clearance between the axle and the bumpstop after the install. Couldn't this be a problem? Could it cause the shocks to bottom out too soon, or other suspension issues?

Now, with the 1.5 spacer for the FJ, but which should also work for the 4runner (KT09127BK), the spacer is installed above the bumpstop: frame > spacer > bumpstop > coil. This moves the bumpstop down, so it would have the same clearance to the axle as before the lift. Wouldn't this be a better design?

I believe the Cornfed rear spacer also sits above the bumpstop, so the clearances would be maintained.

Opinions, thoughts??

I installed it to maintain the factory bump stop height, under the spacer so that the spacer touches the frame.
 
This is the difference between the 4runner and FJ rear spacers. The 4runner spacer is designed for the bump stop to go above the spacer, but the FJ spacer is designed for it to go below the spacer. I believe you'll be fine since there are still the bumpstops further out on the axle which will limit your up-travel and keep you from damaging the shocks.

Are you certain? The instructions, as I read them, called for the bump stop to go inside the spacer and logically I think it makes sense to maintain factory bump stop height?

Are you positive you received the 4runner kit? Here are the part numbers for the rear spacers and the instructions from Daystar's site:
4runner: KT09118BK
FJ: KT09127BK

From the 4runner doc: "Install the coil spring in between the coil spring spacer and the axle."
From the FJ doc (the pics in the doc make this one more clear): "Put the stop bump-stop on the spacer and install the spacer , bump-stop and spring"

My interpretation is 4runner = bumpstop over spacer and FJ = spacer over bumpstop. I've also seen where folks ordered the FJ spacer, but followed write-ups on here for the 4runner spacer, and the rear wouldn't work because the bump stop won't fit in from the top of the FJ spacer. Here's an example: http://www.toyota-4runner.org/4th-gen-t4rs/112562-quick-rear-spacer-install-help.html
 
I installed the 4runner part number Daystar 2.5/1.5 on another member's 4runner. Following the directions included with the kit, which said bump stop on top of the coil. Had no issues. I happen to have the bump stops and FJ Daystar rear spacer laying around. I just snapped these pics. This one is upside down, but you can see the bump stop will not fit all the way in from the top (same as the link I posted, that guy had the FJ spacer and not 4runner, which caused the confusion. I didn't figure this out until after the fact).


But it fits fine in the bottom side of the spacer (so spacer --> bumpstop --> coil).

Yeah, this is the way that I have mine too.

I checked the p/n on amazon and it looks like I do have the FJ spacer... :confused:

Should I swap it out/will that cause any problems? I remember the directions being ridiculously unclear and we had some debate about it while installing the lift.

So I'm a little confused, does that mean that I have the FJ kit? /is that OK?

I have not confirmed if it is possible to install bump stop below the spacer with the 4runner kit. I know instructions say above, but it may be possible to install below (like the FJ kit). Without knowing that, I can't say 100% you have the FJ spacer, but I'd say most likely you do. The front spacers are the same part number, it's only the rear that is different. I have no clue why they make both, but either should be fine. If I had my choice I'd use the FJ spacer (mainly because they are much cheaper).

Yeah, i paid 130 for the kit on amazon with free shipping. It's definitely an FJ kit.

It's been riding just fine and I would imagine that it's probably better to have the factory bump stop height maintained while I'm using the stock shocks, yeah?

IMO, yes, but I don't think there's anything "wrong" with the 4runner version. There are other bump stops outside the coils that will prevent things from compressing too much.

And I'd imagine the sway bar would limit the axle's ability to travel too assuming that the OP still has it attached?
 
I bought the FJ spacers for mine. They work great and the bumpstop is indeed exactly like it was stock. However, I posted a thread about this last month because to me it seems like the bumpstop is way too close to the coil perch in stock form. I don't see how in the world you can get decent downtravel with the bumpstop this close to touching. I might shave some of mine off.

WXman, What did you end up doing? I posted about this too after loading up to go camping and was riding on the bumpstops. I know they have give, but I agree with you that it doesn't seem to have enough room to allow for down travel. Like I posted in my thread I have gained 1.5" in height but not in travel and was thinking about cutting mine down aswell.
 
Haven't done anything yet...but will probably shave off that bottom section of the stops. They are ribbed in three or four segments and the bottom segments on mine are going to disappear.

couldn't you just move it on top of the spacer instead??

No as Ark explained, the FJ spacers go above the bumpstop isolator and the 4Runner ones install between the bumpstop and coils.

I know - I have the FJ kit and it fit in both locations.
I chose to maintain factory height but for those who want more travel, instead of cutting it it could be worth it to move the bump stop n top of the space. though i suppose it's easier to cut than it is to drop the axle and blah blah blah
 
When I was installing mine, it was obvious that they were designed to only fit one way, so for safety reasons I didn't try it otherwise. I'm not sure how you got that to work.

In any case, a sawsall will take care of this issue in 10 seconds.

Yeah, me either :confused:

That's what I would do. You can always save the little bit and reattach it with epoxy if need be.
