Helper Spring, Set Of 2

Helper Spring, Set Of 2
best helper springs on the market
This was the second set of these springs I ordered for my welding truck because the rear leafs are old and worn out with the big weldin machine and bottles my truck bed was sinking way down when all loaded up. After adding these springs and tensioning them all the way down, the truck drives much better. There is 95 percent less body roll around corners. The braking feels more responsive. Theres no feeling of axle wrap. Some other driveline sounds went away. These springs are very easy to install and takes only about 5 or 10 minutes a side with a 17mm wrench. What I did notice is that these springs were most effective when they were clamped all the way down with u-bolts. I love these helper springs, they are simply the best hands down and If i ever have another work truck with serious weight or loading in the bed, I will add these first before even thinking about loading the weight. thank you and god bless.

Great product
These leaf springs did exactly as promised. My truck rides much smoother with the weight of my tools in the bed and does not hit the bump stops when I hit a speed bump or a large pothole
