I've got the Revtek spacer w/top out spacer up and diff. drop up front and OME 890s in the rear. I really like this setup, and to date haven't had any troulbe with it.
My only real problem with my current setup is the back sits about .5 to .75 inches higher than the front. I know thats not much, but I really can't stand the raked front end look and was looking for a solution.
What I was thinking about doing was ordering some of Andy's topout spacers and stacking them on top of my Revtek topouts. I know that I've got enough thread on the three bolts to hold another spacer, but I was just making sure that it was alright to stack them (Has anyone else done that?).
Also, I wanted to make sure that I'm not going to ruin my CV joints if I do this. With the 285 MTRs, the front fender is about 38" and the fins of the CV joint barely touch in one spot. Do you guys think I'd be alright to go up another half inch in the front?? Thanks for the help guys!

 

so you have a 2" revtek topout spacer so far? the OME 890s sit at about 2.5 - 3" lift. Yes it is safe to stack top out spacres... atleast it's safe to stack Andy's top out spacers but I'm assumign ti wouldnt be any different stacking andy's on top of the revetek ones you have. If you have the diff drop, as long as you dont go over 3" of lift in the front your CVs will be OK.

 

My current setup is the complete Revtek front kit, which consist of a ~2.5" spacer in the coil pack and then a top out spacer for another .5". The lift is supposed to be 3", I probably got somewhere between 2.5 and 3. With another topout spacer my front lift would be over 3", but not much. My CVs look good with my current lift, so I'm hoping another .5" won't hurt too much, but I just wanted some opinions so I don't screw anything up.

 

Anybody ran this setup?

 

in general it isn't ideal to stack top out spacers. why not just get cornfed or toytec or some place (or andy, if he does this) to make just one top out spacer to replace the current one - that way you will avoid any problems that might come with stacking them ... and it shouldn't cost much more.

 

I've never heard anything bad about stacking top out spacers... ive got a friend who has andy's stacked and realy likes them. But r0cky's idea is good too if you can have someone custom fab you a 6/8" (or 3/4ths) inch top out spacer. Andy's page that talks about his spacers has a bit of info on stacking them too I believe.. or he mentions that it is do-able.

 

i have a pair stacked. the problem w/ making a single 3/4" thick spacer is the price. it would be nearly triple the investment in materials and about the same upcharge for the time to cut it on the CNC router. that would mean that instead of $75 for two pair, it would be about $110 for a single set of 3/4" spacers.

there is no disadvantage to stacking a double set as opposed to using a single spacer. there is no difference in strength or anything else since the greatest loads (tension, compression, and shear) are all forces on the bolts. the only load on the spacers is compression, and those loads are dispersed over a large surface area on both the upper and lower faces of the spacers - as much contact surface area for loading as the stock arrangement.

HDPE is some tough stuff... very tough.
