Brought my S10 to life again!!Front, Driver And Passenger Side Shock - Front Spring Assist, Set Of 2
5.0/5
⭐⭐⭐⭐⭐ Completely Cured the "S10 Sag" – A Total Game Changer!
If you own a Chevy S10, you probably already know about the dreaded rear-end sag. After years of hauling, my leaf springs were looking pretty tired, and the truck was bottoming out over speed bumps even with an empty bed. I decided to give these spring-loaded shocks a try instead of replacing the entire leaf spring pack, and I am absolutely thrilled with the results.
The Install: Installation was a breeze. They were an exact, direct-fit replacement for the stock shocks. If you have basic hand tools and a floor jack, you can get both sides done in about an hour.
The Ride Height: As soon as I dropped the jack, I noticed the difference. The coil springs on these shocks gave the rear end just the right amount of boost, bringing the truck perfectly back to level.
The Performance: Unloaded, the ride is slightly firmer than stock but feels incredibly planted and secure—no more body roll around corners. But where these really shine is under a load. I threw a few hundred pounds of gear in the bed this weekend, and the truck barely squatted.
If you use your S10 for hauling, towing, or just want to revive an old, tired suspension, buy these right now. Best money I’ve spent on my truck in years!
⭐⭐⭐⭐⭐ Essential upgrade if you use your S10 for work!
I use my Chevy S10 as a daily workhorse, and the factory shocks just weren't cutting it anymore whenever I loaded up the bed or hitched up my small utility trailer. I swapped them out for these load-adjusting spring shocks, and it transformed the truck.
Pros:
Eliminates squat: Handles heavy loads of mulch, gravel, and tools without burying the tires in the wheel wells.
Easy swap: Bolted right into the factory mounts.
Great value: Much cheaper and easier than adding add-a-leafs or swapping the whole spring pack.
Cons:
None so far! Just keep in mind it will stiffen up your unloaded ride slightly, which is exactly what a real truck needs anyway.
Five stars. Don't hesitate if your S10 needs some extra backbone!

Look to be a good quality part, haven’t installed yet but they feel premium. Packaging wasn’t the best, but I didn’t pay for the box. I paid for the shocks so still 5 stars. Once installed I’ll update.

Question: I have a question; are all the parts and pieces included in this kit? I don’t see the Schrader valve, nor a way to mount it. Are all the hoses complete with all its connections ?

Hi Joe, I'm glad to be of assistance to you. These have adjustable air pressure to custom-tune each individual load weight which must not exceed vehicle GVWR (Gross Vehicle Weight Rating). These products do not increase payload. If interested in this set, use the link below to order at 4% off the regular price today while supplies last. I hope this is helpful.
