trailing arm question
 
Hi ..
I was wondering if anyone here has ever tried to make a "kick up" on an stock trailing arm instead of lowering with blocks?
does it work or is it completely unreasonable??

Re: trailing arm question
 
Welcome to the forum BirchRidge. Are you talking about cutting a stock T/A and raising it up to create a drop? Seems like the torsional fatigue would be a concern.

Re: trailing arm question
 
okay .. any other tips on how I can lower the rear without drop coils,
they are very expensive in sweden when the dealers put on high prices ..
I may be a greedy dumb ass swede but if you donīt ask, you get no answer :)

Re: trailing arm question
 
leave the Swedish dealer out of the picture and order directly from one of our board vendors ...

What is the exact issue w/lowering it using blocks & drop springs?

BirchRidge 10-14-2010 05:52 PM

Re: trailing arm question
 
there is no problem with using drop springs & blocks more than it costs me half month's payment to buy drop springs over here, how many inch can I lower by using just blocks?

Shane 10-14-2010 06:31 PM

Re: trailing arm question
 
again, why can't you buy them HERE and have them shipped there?

wouldn't that save you some money?

With a 15" wheel diameter, you can run up to 1.5" lowering blocks w/o scrub-line issues. With 17" wheel diameters, you can go to 2" blocks w/o issues; 18+" wheels you could go 3" blocks but the truck arms will become very visible.

Try these......

Shane, who should I contact for prices and info on a lowering kit over there?

Re: trailing arm question
 
BirchRidge, don't you have companies that make springs locally? This would have to be much cheaper than importing them from the US.

Hey Ray, I think there is only one spring manufacturer in sweden and they are not cheap, and produces only springs to modern sports cars. a set of springs for my pickup costs about 10000 sek here which is about $ 1500.

Scotti when u you mean scrub line issues i assume your talking about the trailing arm now sitting lower due to the blocks, and the arm possibly rubbing on the ground.

My question is what in the world does wheel diameter have to due with it. Don't u mean overall tire diameter?

Example; I run 16 inch rims w/ 235/85 tires ....31.7 inches in diameter!!!!

Most 18 inch wheels w/low profile tires (35-40 series) are now where near that
tall ....It all has to do with aspect ratio of the tire. Even a 70 series 15 inch wheel tire would be close if not taller than lets say a 40 series 18 inch wheel

Wheels are solid material so the OD of the wheel does not change in the event of a flat. A 29" tall tire on the other hand can go flat winding up much shorter thus making that wheel diameter the one thing that keeps you above the scrub-line.

Got it Scoti ....wasn't taking in the account of the flat tire scenario ........

"if it aint broken ....break it ....then you have an excuse to mess with it"

I made a set, I haven't been able to install them yet but it is doable.

^Holy cow!

You guys have jeeps over there? Slap a set of TJ springs on it! 5" Rear drop 0 load capacity though.

Those are still awesome in my book...... even if they haven't seen real use yet.
