1994 1LE Shock Valving?
Hi,
I need to replace my shocks on the vehicle, but not sure about the springs. They're different with specific loading that came with this package. I'm trying to find close to the 1LE OEM shock replacement for the rear, which I can do myself, and also for the front. I'll have to have a shop perform the swap on the front, cause I don't have a coil over spring compressor.
I pulled this from the webs that has some details on the components of this variant where it discusses specific shock valving:
With 360# linear springs in the front and 160# in the rear I'm not sure what would be a similar replacement shock for the 1LE.

1993 brought the LT1, 6 speed and stiffer fourth gen chassis into the 1LE history. Unlike the thirdgen 1LE, the fourthgen had the same brakes as the other V8 F-bodies. The suspension was the main attraction in '93. Featuring stiffer springs at 360# linear springs up front and 130-160# progressive springs in the rear. Also included was a 21mm rear sway bar, 32mm hollow front sway bar, higher durometer control arm & panhard bushings and a solid rubber transmission mount. All '93 F-bodies with a V6 received the 275 hp LT1. Performance was the sole purpose of the 1993 1LE. These cars were sold without power accessories, T-tops or air conditioning, and aluminum drive shaft that was part of the thirdgen 1LE package is mysteriously gone in '93. Shock absorbers were DeCarbon with 1LE specific valving. 19 Camaro Z28's & only 3 Firebird Formula's were equipped with this option in 1993.
1994 & 1995 are the same as 1993 with a couple exceptions. The LT1 was converted to sequential mass air fuel injection from the batch fire speed density system used in 1993 and the rear sway bar was reduced to the 19mm bar used on all V8 F-bodies. 1995 cars sold in California were equipped with dual cats and power increased to 285 hp. In 1994 135 Camaro Z28's and no Firebird 1LE's are built! In 1995 106 Camaro Z28's and 2 Firebird 1LE's are built.

Re: 1994 1LE Shock Valving?
I found this also from back in 2005
Here's a great write-up from the F-Body.org FAQ section:
Q: What's included in the 1LE performance package??
A: The package required these options (Z28/Formula, respectively):
Basic option group (FZAB/1SA)
A/C delete (until 1996 when A/C became standard)
6-speed tranny or performance rear axle with the automatic (GU5/G92)
Z-rated tires w/ 150 speedo (QLC/QLC)
Base stereo
and it consisted of:
Higher rate front springs (360 lbs/in for mid-1994 and after)
Variable rate rear springs (130-180 lbs/in for mid-1994 and after)
Stiffer front and rear shocks (Koni double adjustable for 1996 and after)
Harder bushings (front upper/lower and rear control arms)
Larger diameter anti-sway bars (32mm front, 21mm/19mm rear)
Increased cooling (for 1995 and after)
Engine oil cooler (1993 - 1995)
The 1993 1LE cars had the same springs and deCarbon shocks (but with much stiffer valving) as on the stock Z28s and Formulas. Initial 1994 1LE cars received the same set-up, but sometime during model year (between Dec 94 and Mar 95), the 1LEs received stiffer (higher/variable rate) springs and the shock valving was slightly reduced (but still considerably stiffer than the stock deCarbon valving). Due to the stiffer springs and modified valving, the 21mm rear sway bar was dropped in favor of the 19mm bar (which was the same as on the stock Z28s and Formulas). In 1996, the Koni double adjustable shocks became standard on the 1LE cars. Increased cooling on 1995 and after models was accomplished by the addition of an air conditioning radiator baffle even though no AC was available in 1995. Also, after 1995, in order to get the 1LE on the Firebird or Trans Am you had to order the WS6 package.
Here's a list of suspension parts and prices for 1994 models:
