I picked up a set of Hall shocks, pre-owned but basically unused. These are the Aldan bodies with Hall Pantera stamped 4.5” ID springs. The two pairs are different as follows;

1 pair extended length 15.5”; compressed length 12.5”: Springs; Orange 10” length, 0.588” wire size.

1 pair extended length 14.5”; compressed length 11.5”: Springs; Black 10” length, 0.688” wire size.

On researching past posts here on the forum, I installed my original rubber spring seats and installed the front pair today assuming the orange lighter spring (although longer?) set are meant for the front. Based upon a previous post I installed them upside down so the height adjuster ring and dampener valve set are actually accessible. But I was surprised how high the car sits even at the lowest thread I can go (where the spring have basically zero preload). Admittedly it is slightly lower than the stock shocks were previously, but I was hoping for a still lower front stance, there is certainly room to go lower looking at the tire to fender gap.

Is anyone on this forum running these shocks and if so how have you found them for ride height adjustment, handling and performance?

Does anyone also know the spring ratings that Hall sold them with? Aldan’s go by color code but don’t have any orange or black listed on their site and the springs have a Hall Pantera motif.

Thanks
Julian

Julian I do not have these shocks and know nothing for certain, however I would think that the larger spring wire diameter would go on the back of the car since that is where the most weight is. I have heard spring rates in the rear should be five to six hundred pounds while in fron three to four hundred. I have also heard that Hall made shaocks that would allow for an overall one inch reduction in ride height. That may not sound like much but it cab dramaticaly improve handling. Also it looks to me like you would want a forward rake to help keep air from under the car.
DeTom,

Thanks, I too am convinced that the lighter wire (orange springs are for the front), however I'm confused why the front shock body would be longer than the rear? I'm actually wondering whether at some point they have been assembled with the wrong springs on each pair of bodies. For front down rake it would seem more appropriate that the 1" shorter shocks went with the lighter springs.

I'll give Hall a call during the week to try and verify, failing that I may actually take the springs to work and use a hydraulic press to compress them 1" and see what the load ratings are.

I have this set up on my car. Slight difference is that I have the newer dual adjustable shock but the same body shock. I forgot what Gary told me the spring ratings are but I believe that De Tom is correct. I run 335 35ZR 17 on the rear and 225 45ZR 17. Gary told me there was no need to run the insulators on the spring so I do not have them installed with no issues. Front the top of the rear tire I have 1 1/2" between the top and fender lip. The fronts have 1" on the same measurement. Looking at the rear shock on the threaded part, I have 1 1/8" from the top of the threads to the top of the lock down ring. From the orginal Konis that were on my car, it lowered it over 1 inch. With my tires, if I go lower, it interfers with the fender lips on normal bumps. And black spring is the rear and orange is the fronts.
Julian,
Did you go for a ride?
I put on a rebuilt set of Koni's with the Hall springs and got sceared as hell when I got HyprDrv back on the ground. Car sat with about 3 inches between the tire and the fender! I took it out for a ride and low and behold I dropped down to where I was suppose to be. Sometimes it's the simple things....

Okay, got the info direct from Hall, apparently the springs are the only ones they use with aluminum shocks as follows;

Orange front springs at 400#
Black rear springs at 680#

They also said I must install the OEM rubber insulators/spring locators into these shocks (which I had done anyway).

Thanks for all the replies.
Julian
