Lowering Blocks

[nivvy]

Im thinking of lowering the challenger 2" in the rear... I just love the tucked look! Will this affect the performance of the car???  I am running SS springs ....

[Chryco Psycho]

no problem go for it

We had traction problems with the Valiant when we tried that   

[Chryco Psycho]

I wonder why that would be ??

[Travis72]

Because wouldn't lowering it with blocks change the pinion angle?    

If you decide to run blocks, be sure and only buy billet aluminum ones.  Not the cast junk ones from Autozone or someplace like that.  Trust me, it won't take long to crack the cast ones (I had lowering blocks on my Dakota and the cast ones cracked).  You can get billet ones from All Star performance or most online places that cater to circle track racers.

Shouldn't be a problem.

I've got 2" blocks in my drag car. Extruded aluminum from Speedway Motors out of Nebraska. I did angle cut them to get my pinion angle where I wanted it. I've had them in for about 8 years without any trouble.

[nivvy]

Yes HP2 I got the 2"ones from speedway...the aluminum ones.......the only thing is if I lower the car I wont be able to put the 28*13.5'sMT tires in there! Oh Well I guess the the 28*12.5 will have to do ... 

I will have the block cut for pinion angle...

[Chryco Psycho]

the pinion angle shouldn`t change but it is a good way to correct the pinion angle if it si off

[nivvy]

When using the blocks will the springs at stand still wanna arc up / flatten out or stay them same which is what I am thinking

[Chryco Psycho]

the spring will stay the same , it will have the same weight on it 

[Hopalong]

Wouldn't they cause a lever effect on the springs?

[HP2]

They do provide greater leverage than having no blocks, but SS springs are so stout in the front segment that it isn't a problem.  The also alter the rear roll center location by raising it half the height of the installed block, which also isn't a huge detriment. It isn't the ideal set up for a handling application, but for a street/strip combo is it still highly livable.
