Superior 18-1601 Rubber Coil Spring Booster, Small

bought them for my 2005 mazda6s wagon since the wider tires + wheel spacers = fender rob in the backat first i was thinking about getting stiffer springs at stock height. as i researched the springs I stumbled upon these rubber coil spacers.i got a set from local oreilly store and they worked well. i got another set from amazon (cheaper) to install between the first set just as a safety measure since they cost $5 shipped anyways.prior to the 18-1601, i've also tried:18-1901 (too low)18-1920 (too high)18-1601 is just perfect for my wagon

Installed on the front coils of my 68 mustang. Had to use a spreader to get them installed. Spring sag and a slightly taller tire was causing some tire rub on chrome trim in turns. Installation gained about 1/2” lift on front using shorter side of stiffener. No tire rub during test drive after. Drilled hole mid stiffener and installed zip tie to retain in case of pothole. So far, so good.

UPDATE:The wife's car started scraping again, so upon inspection we found that 5 of the 8 had fallen out at some point.We ordered another set. Only this time, I drilled holes through them, ran zip ties through them, and zip tied them to the springs. They shouldn't go anywhere now. I recommend doing the same. See attached pic.Original post:Used these to lift a 2012 civic hybrid that wouldn't get into the garage without scraping under the middle of the car. The spacers lifted it about 1.25", and didn't change the ride quality that much.THESE ARE DESIGNED TO USE 2 PER SPRING, OTHERWISE THERE WILL BE TOO MUCH PRESSURE ON ONE, AND THEY'LL SPLIT (like other people's complaints). If you use them correctly, they work fine. Order 2 sets.

First, they were easy to install. Did both fronts in about 15 minutes. Second, I installed long side to get the max 1.5" of lift on my Polaris Ranger 500. My tape measure showed only gained .5" not the 1.5" as advertised.Third, honestly, I don't think they are worth the money. Buy at your own risk

All good!

I purchased 2 sets of these. This first set I thought I may have installed wrong, the second set lasted less than a week, just like the first set. These were installed on a Honda min-van so they were not overloaded,. When I replaced the first set I discovered pieces of the first set inside the coil springs indicating that these had just broken in half. If they cannot hold up to a mini van powered by a 4-cylinder engine I cannot imagine them holding up in any other application.

Good product as advertised. Good price... reliable...

FRONT SPRINGS WERE WEAK ON TRUCK
