I know this gets post regularly, but I didn’t find a current post. I am looking for a set of the old hijackers that actually raised your car. I believe they were #15130.
The new version hijackers add load capability, but don’t raise the car.
So, as far as my research shows, need to find a set of the original hijackers for a 57.
Appreciate you help.
The new style did not raise mine much at all, two different sets, just got hard. Just as an fyi, here is the issue that I ran into. I found a set of never used hijackers for a trifive. They were perfect, raised the car up to where I wanted. Then i discovered that while they were new, one of them would not hold air longer then a couple of days. the bellow was leaking a little bit of air. Age got the better of them. The other issue is finding a real Gabriel air hose kit. I have one or two nos sets so if you find a set of hijackers, and you cant find a air hose set, let me know and we can work something out for the hose kit.
Otherwise, you might just swap in the 3 inch lift springs that are on the market and use some traditional shocks.
Thanks for the thread. I bought a couple sets off ebay awhile back and after installing they did little to nothing for lift. Disappointed , I set them aside feeling I got taken on the buy. Now that it has come up I should do some investigating and find out more. I actually thought maybe there was a plug at the shock between the line and shock that I may have overlooked.....sometimes the easy or simple problem can be overlooked .......at least for me....lol. Since the replies reflect yay and nay on lift are there two different shock numbers to look for?

Frame-mount cross bar is a necessity with air shocks
When you get your hi-jackers, if you don't have one already, it will pay to get one of the frame-mount shock cross-bars to mount them on. About 35 years ago, before they made cross-bars, I had a hi-jacker over-extend; when they do, the piston goes straight up to it's highest point; Where the shocks are mounted from the factory, it ripped out the spot welds fastening the trunk pan to the floor pan very easily. I think the original placement was engineering done while on the toilet seat (-:
