Anyone use lowering blocks? - 07/13/13 09:14 PM

I am thinking of putting the rear down some..are the aluminum ones ok? Ive seen cast aluminum and billet alum and steel. Any recommendations? Does it affect 60 ft times negatively? Pinion angle? .. might need the 2 inch, but possibly 1's. Thanks in advance..

I use 1-1/2" lowering blocks on my Dart. I went from a 29.5 tyre to a 31 and it started handling badly, so i fitted the blocks it dropped the rear end and was fine again. Use the billet ones though, not the cheap ones.

I'm using billet blocks on mine.

I used them to lower it AND improve the 60' by changing the pinion angle by milling them to the specified angle I wanted.

I have them on the Fury, I needed to get the stance right with superstock springs and 31" tires

find your local 4x4 shop they will get you the steel blocks square or tapered, u-bolts and *shims

I run 1" aluminum blocks from Caltracs with no problems ( their springs, perches, spring clamps ). Change to pinion angle is negligible.

I think cast iron would be acceptable, but prefer billet aluminum or steel.


DO NOT USE CAST ALUMINUM!!! I've read many internet reports of them crumbling to dust over time.

I have cast iron blocks on my truck now, but only been on there a year, so no real long term longevity reports yet, but I can say that the truck handles fine...about the same as without the blocks.

I would use some decent aluminium or steel ones. Make sure you regularly check your U bolts as they will tend to work loose.

My recommendation is to lower the rear using the hangers with the extra holes sold by companies like firm feel.

Leaf Spring Hangers
"to fit leaf springs with 20" or 22" front segments in your B-body."

From the website: These hangers are HD reproductions of the OEM hanger with the addition of an extra upper eyebolt hole so the car can be lowered 1.5 inches. The hangers are made from 0.188 steel, zinc plated for corrosion resistance and come complete with the OEM style hanger studs already pressed into place. Use the lower eyebolt hole location for stock ride height

I have news for you...
Lowering blocks are a compromise.

Going fast is dangerous and people get killed from hardware failures and bad choices. Try to make good choices.

From someone who does goes very fast doing road course 3.4 mile long hot laps for 45 minutes at time vs 1320 feet @ 10 seconds at a time.
