The Hellwig Pro Series is a versatile, effective helper spring designed for professionals and Do-It-Yourselfers alike. It installs using common hand tools and includes all the hardware instructions you need to install it right in your driveway or professionally. Once installed, the Pro Series assists your vehicle in keeping its stability even when hauling or towing massive loads. With the Pro Series you will find much better load assistance, better sway control and easier handling even when hauling the heaviest loads. This kit increases your vehicle's level load carrying limit all the way up to the manufacturer's GrossVehicle Weight Rating*.

The Pro Series Helper Spring is manufactured in Hellwig's California facility from heat-treated ASTM 5150 alloy steel. Its progressive rate design helps the Pro Series Spring automatically increase its resistance rate as your load increases. This more dynamically accurate load resistance better prevents your vehicle from sagging and dragging when hauling major loads. Better yet, you can fine tune your Pro Series Helper Springs as your towing and hauling needs change. By simply adjusting the provided heavy-duty U-bolts with household tools you can tune your suspension to your specific hauling habits.

>The Pro Series Helper Spring "Silent Ride" feature improves your overall driving experience. This feature includes a block made of polyurethane located between the main and helper springs. The block helps to silence the spring, making your ride more comfortable.

Hellwig makes your Pro Series Helper Spring in the USA with the highest quality components, and backs it with a Million-Mile Warranty.

*Note: Never load your vehicle beyond the manufacturer's GVWR.

Great kit, and great pricing by Auto Accessories Garage. Install wasn't too bad, but be prepared because depending on your application there could be some deviation to the instructions. Hellwig has 6 star customer service, so if you hit a small snag give them call.

The springs are high quality and I think will do what I got them for. They are being used on an old trailer made from an old Ranger PU of unknown vintage that I use to haul water (300 gal.) for stock. I am, overall, very satisfied with my purchase. That being said, there was a bit of problem with some of the parts. The instructions call for certain of the "U bolts" to be straight "U bolts" and some of them to "off set". What I received was two more "off set" ones and two under sized "U bolts. That became a problem when I attempted to install the polyurathane silencers. I was able to get the springs installed after some jurying but the whole process would have gone better with the correct parts. I may try to contact the Hellwig company to see if I can get the right parts.

I think the box they came in should be stronger. I think you should tell people what to adjust and what it does. I also think you should put lock nuts in with them.

Easy to install and great appearance. Finish on springs seems as though it should be resistant to weather and rusting. Received several comments from friends as to how good they look and the use of the bushings to dampen the noise.

Product works good. Directions could have been more clear on how much to clamp down on front and back bushings/isolators. Other than that pretty easy, hand tools with a jack in your driveway.
