Hellwig 815 LP-15 Helper Spring Kit

I used these on a 07 Nissan Frontier. They worked perfectly and were a fraction of the cost of the kit made for my truck. Also I bought them in the used section on Amazon and had no problems, everything was there and looked like new.. My old worn springs used to sag a lot under load. These have greatly improved my ride quality under load and when not.

2003 Astro cargo used as a service van. With rear Adrian Steel tradesmen box, rear end always sagged. After adding another 300lb air compressor, you can imagine the sag! My technician has reported that the van now rides better than it ever did after spring kit install

Zero lift & rough ride!

My 99 Ford Explorer had about 4" of rear end sag. after installing these helper springs, it raised my Explorer and left me with only about 1" of rear end sag. It has also greatly improved the ride of my Ford.I was going to replace my entire rear suspension, but now that I have installed these springs I can rest easy and put the money into something more important.

Since original purchase I have transferred these helper springs from truck to truck. Original fit was on a 2000 Tacoma 4X4 and currently installed in a 2006 Tacoma 4X4 Double cab. I tow a small travel trailer and these helper help correct the slight tail drag that I experience when the rig is loaded in tow. I plused these up with some Firestone Air Springs as well and now have zero drop when the trailer is attached. Good first step to solving drop problem. Very easy to install with hand tools.

Put them on a Durango to help the trailer load, maybe took 15mins for both sides

Update. Lowered to three stars. While they appear to help a bit with an unloaded Durango they did absolutely nothings when i dropped my travel trailer in the ball. The Durango sunk as much as it did with these not on. Plan returning these and replacing the OEM spectrum shocks with higher load rated shocks.

Just finished installing these, took about 20mins, went for a small test drive and immediately noticed the difference, every time i brake, corner or hit a bump the rear of my 2000 explorer feels how it should. Definitely worth the investment if you dont want to install new leaf springs
