drop spindles or springs?

Post by Cdub74 on Thu Jan 06, 2011 11:53 am

still searching for a way to lower my front end. Im going to end up (in the long run) replacing the whole suspension with Air Ride, but in the mean time my front end has HD springs which makes the front end tip up. So heres my question, ive seen 2" drop spindles, also -2" springs from Eaton Springs (which are HD). What will BEST help the front end drop for a nice stance without having my 454 slam to the ground when I go over a bump. Exclamation Question

If you will be doing air bags later, just chop the springs for a harsher ride. If not, go with the spindles and for a really serious drop put the springs in also. personally, I can not go shopping anywhere they have those stupid speed bumps because I drag and I have stock springs and spindles. JB

If you decide to cut your springs, only take one full coil out. Before I installed the coil-overs, I cut two full coils out of the springs, and regretted it. It looked cool, but rode like $hit. It was awful.

It would not be at all good on the strip, but it would do wonders for your cornering ability. JB

A drop spindel sounds safer, doesn't it? There only like $150 a pair, plus I can keep the spindels in when I get Air Ride.

Have you checked out the factory spring rates?

http://www.g3gm.com/t2376-front-spring-rates

Even with the best factory HD springs the rate is only 460. Compare that to the aftermarket lowering springs with closer to 650-700 lbs spring rate. Cutting one coil is going to raise your spring rate, but it's effects would be negligible. Probably raise you up to aftermarket spring rates if anything. OTOH you need to be careful & not get the springs too hot when cutting them. A cutoff saw or sawzall should do the trick while applying oil to the spring. DO NOT USE A TORCH & don't even think about heating the springs to compress them! This is where some people get the bad vibes about tampering with springs due to them becoming brittle after the heat is applied. Another thing to remember with lowering springs is that an alignment is gonna be necessary.

Drop spindles would be the way to go if it's a more permanent solution, but be cautious of no name spindles. They could be made by 7 year old foreign slave laborers & won't hold up under rigorous driving. Where did you find some that cheap? I think McGaughy's is the cheapest I have seen & they are around $250-$300 depending on where you find them.

Got a link? I just scanned the website & only came up with these for $234.95
http://www.summitracing.com/parts/CLP-7078DS/

Here's the McGaughy's ones that I mentioned.
http://grunionfabrication.com/drop-spindles-7078-chevy-camaro-7377-monti-carlo-camin-p-1949.html

Yes, the 70-81 F Body & also the 77-96 B Body uses the same spindle, so don't limit your search to 73-77 A Body. Then you can open yourself up to PST, BellTech, & probably more companies. The only thing that concerns me about drop spindles besides quality is clearance. Will your wheels rub the lower A arm after installing drop spindles? Most people shouldn't have to worry about it, but for anyone that wants ultra wide front wheels, it might be something to consider.

Look again. The highest spring rate is 500 lbs/in. 1973 Buick w/455 had them.

Thats what mine looks like sitting on level ground, a 4x4! Well just the front end, I have lowering springs in the back. So Ill take off ONE coil (without a torch) and see how she looks, anything will be better then it is now.

I stand corrected. Still not up to aftermarket rates, but definitely something to consider for the restoration guy that wants to improve handling.
