It Doesn’t Get Any Better than Mega
Your Turbo S is one heck of a rig. With its extra-wide suspension, you can keep the pedal floored around more often than not. But when you upgrade to bigger tires, you need ball joints that can handle it. With Keller’s Mega Ball Joints installed on your Polaris RZR XP Turbo S, you’ll be able to take your machine to its limits and beyond without busting a ball joint. They use oversized components and a two-piece design for unbeatable strength.
Unbeatable Mega Strength
Bigger is better, that’s why Mega ball joints use bigger housings and studs. The bigger housings are made with durable tool steel and make room for massive studs. The studs don’t neck down as much as the competition and use a massive ball for extreme strength. These ball joints are so big, they require you to modify your A-arms to make them fit. They’re for folks that need reliable strength above all else.
The Most Durable Ball Joint Around
Keller Ball Joints aren’t just the first threaded ball joints on the market—they’re also the most durable. Once you press the joint into your modified A-arm and thread the housing on the back like a nut and bolt, there’s nothing that’s gonna get it out. Plus, they’re made with hardened chromoly from top to bottom so they can take the heat. And since they’re easily adjustable and greaseable, you can keep them running smooth for years.
Ride However You Want
When you upgrade to Mega Keller Ball Joints, you can upgrade the rest of your machine without worry. Get wild with bigger lifts and meaner tires—with massive components and a two-piece design, you can push the limits and forget about bringing spare ball joints on your next ride.

Good value
Model: NewSLS50_52, Model: NewSLS50_52
Working perfectly. Install of stereo equipment and carpet left me wanting some heat and sound resistant materials.

BUY THIS ONE!
Model: NewSLS50_52
This is one of the good ones. There are other brands just as good, and manny brands are worse, but this handles well, rolls down easily, doesn't come off at all easily, and adapts to dips and curves like a champ.
Appropriately heavy and dead, I'm happy with the way it smothers panel resonances and even at muffling direct sound, like a big hand over my Uncle Harry's eternally noisy mouth. You can rip the foil but you have to work hard at doing that.
Remember to buy a brayer; you can roll overlaps nice and thin. Also remember to pre-wipe the sheet metal with a decent solvent like acetone or Stoddard/Varsol. It should last forever.

Good stuff, but watch the temp
Model: NewSLS50_52
I used this in my single cab pickup truck (89 ford.) It only took half the box (10 sheets or 25 square feet) to do the floors, but I bought the big box because I plan to do the doors, back wall, and maybe the roof as well. One thing I learned is that the temperature matters when you’re doing the installation. It was around 55F when I started in the evening, and when it dipped down into the 40s the sheets would not stick to the metal, and were hard to compress with the roller. That’s why I ended up only doing the floors and not any vertical surfaces; i will have to wait for a nice hot day. The other thing is that the foil layer on top is razor sharp at the edges, definitely wear gloves! I didn’t notice until after but I have little papercuts all over my fingers. Aside from those things, the install was easy and straightforward. The sheets cut easily with scissors, and any goo that ends up on your hands or scissors can be cleaned up with acetone (nail polish remover), or lacquer thinner. I would use this stuff again.
