Hockey Pucks for rear...

Uttles · **Posted:** Sun May 18, 2008 4:50 pm

So I used two pucks per side in the rear. I have OME HD lift. Did I use the correct number of hockey pucks?

Just need confirmation before the construction adhesive sets!

Thanks

Well, I used 3 hockey pucks per side. I used 2 at first and I got rub from my rear when I had it stuffed in the fender well. Now I have three and no rub. I took it out yesterday to test it and the 3 pucks worked great. I have the long travel OME rear shock so my rear end can articulate pretty good. tjkj2002 was the guy who told me to use 3" bumpstops and he was right. He uses 3" stops that he got with his skyjacker coils. Here is the link that we have been discussing the rub and proper bumpstop size.

The tire may look like it rubs, but there is a couple of mm of clearance between the tire and the fender all round. I run 31X10.5X15 tires btw.

Hope this info helps. BTW I run a Frankenlift Premium II kit with full OME.

OK cool.

Sounds like I did it right for my lift as I don't have he frankenlift, just the OME springs etc. But when I look at it, it looks like there will be hardly any flex. Well, at least the tires shouldn't tear off the fenders.

We'll see next week how it performs off road.

Font stops are on the way from Terraflex.

Cool, post some pics of the bumpstops being put to use.

I am not being a smart stupid but does any one know of an online supplier where I can buy hockey pucks from?
I live in south Louisiana and we just dont have a need for any thing other than footballs and basketballs

maybe ill get 2 more hockey pucks, i have 2 per side right now, but only have 245-70 tires, but the rear flexes so much from the RSX17004 that the bumpstops dont touch 100%, so ill add another one on each side

Just so add a question

I have a OME HD lift w/ standard length OME Shocks. I've yet to install bigger tires or bumpstops, to see I ramped up the jeep on opposite ends (front left, rear right), at max extension of the shock the stock bumpstops are touching and the coils are no where near stacking. This may all change by up'ing tire size I suppose but at this time I see the need for no more than 1" of bumpstop (which I'd add only to make sure the shock never reached full extension).

I can see adding the stops to reduce a rub yes but to prevent flex well before the point of max shock extension/ stacking the coils I don't understand and an explanation of their need in the situation would be great.

The most important reason for bump stop spacing is to prevent your shocks from bottoming out on them selves
they can hold the weight of the axle that is part of their job but they can not hold up the weight of the jeep and will bend
or fail if the are over compressed
Then there is the other stuff rubbing and spring stacking

Well then in my case, adding 1 " bumpstop would contact the stock bumpstop well before max compression of the shock and would therefore be safe to run w/o reducing suspension movement another 1-2 inches by adding another 1-2 pucks? This again may all change after bigger tires , but I do not believe it should.

Next comes issues with spring stack and rubbing?

Sooo..

This is with one hockey puck on each side:

I drove the jeep up on an angle up a steep hill. It flexed the rear as much as possible.

1. The tire stuffed fine with room to go (so no rubbing on flare or wheel well liner)

2. The springs were not stacked, still had about an inch or so left (maybe a little less)

Sooo...

How do I know if the shocks are not over compressing? Is there a way to tell? Visually? ???

Help would be appreciated...if I need another puck I have to add it soon.

Thanks

I say ad the extra puck. No harm in it, just a little extra work. Better safe than sorry. Say for example you weren't really maxed out when you tested. Without the extra protection you could really mess things up. And for a few extra bucks and some effort it can all be prevented. "An ounce of prevention is worth a pound of cure" as the saying goes.

What I plan on doing is to take the shock off, compress it, draw a line. Flex till it lifts a rear wheel. If there is a gap between the Upper portion of the shock and the line, I'm good. If they meet, it needs more bumpstop.

OME shocks are good with OE bump stop spacing
the ones that end with L need more spacer

Simon says .............right Nick :wink:

The Old rule of thumb is for every inch of lift , one inch of added bumpstop is needed.

Take the shock out and compress it as far as it will go. Mark, with a sharpie, around the shock then put it back on the Jeep. Flex the rear again and see if its fully compressed or not.

That will work to a point but its somewhat different sitting in the driveway flexing than out on a trail dropping off ledges, steps etc.

oh well :roll:

JK, I'm just bitter because your KJ is higher than mine now........ :evil:

Anyone have pics of where they are installing these pucks?

True. Guess it all depends on how the given person flexes it to test it.

:roll:

like those rolls.

here you go JL:

Edit: So according to rock lizard you need to add an extra inch of bumpstop once its fully flexed.
