DETAILS

Tackle the trails with confidence! Let SuperATV's RackBoss rack and pinion system steer you in the right direction. Designed to withstand extreme abuse from massive tires, monster whoops, and the toughest of terrains. Riding can wreak havoc on your steering system. Forget dealing with sloppy steering and upgrade to the industry's leading steering assembly - RackBoss.

SuperATV spared no details with RackBoss and worked tie rod end to tie rod end to engineer not only the strongest, but the longest-lasting rack and pinion on the market. You want bullet proof? Try a housing that has 40% more material giving you added strength where it's needed most - no more cracked housings! You want longevity? Utilizing a 15% bigger rack gear and a wear-resistant Teflon bushing, RackBoss showed no sign or wear or fatigue after 50,000 strokes compared to competition showing obvious wear at 30,000 strokes.

At SuperATV, we understand the need for bulletproof strength and unmatched durability. To ensure an exceptional product, we've increased the size of our tie rod ends, added misalignment bushings, and finished it with the optimal blend of materials and heat treating. Our high strength 4130 Chromoly end is oversized allowing for an increased bearing surface area, leaving you with all-out strength, durability and reliability.

Z-Bend Heavy-Duty Rack and Pinion
Select Z-Bend Tie Rods for your big lift kit and stay in control. Our Z-bend tie rods are specially designed with steel gussets that give you the strength you need with 6" or more of lift. The solid Z-bend tube is made with 4140 steel. The bend is the only way to reach the spindle on a big lift kit without overextending your joints, and it comes with the same high strength 4130 Chromoly tie rod ends that make sure your wheels turn where you want them too no matter how big they are.

Nice wipers
Size: 26"+16"+12"D(U/J Hook)
I got the right ones. Checked and checked again. For my husband's subaru crosstrek. The front ones fit perfect. Installed super easy. Work nicely. Had alot of rain to check them out recently. Now the back one. Does not fit. Not sure what is wrong with it, but 2 out of 3 is good.

Finally, no more streaking and squeaking.
Size: 26"+16"(Top Lock)
Bought these a few months ago for my boyfriend’s car. It was for the purpose of replacing the OEM model that initially came with the car, as the squeaking was driving me nuts. Matching the pair to his car’s make and model here on Amazon was easy. The installation was easy as well, as they simply lock in with no difficulty for me. And they look fine as well. They’ve held up the last few months in the bitter winter here in the northeastern seaboard with no issues. No squeaking, streaking, or scraping. The material seems sturdy and of good stability, not flimsy. Definitely directing him to buy this brand again when they eventually need changed out.

Great price and perfect fit.
Size: 26"+20"+12"B(U/J Hook)
All three blades worked great for my 2023 Grand Cherokee. Well worth the money! Make sure you know how to take the old blades off! I had issues with the rear blade, but finally worked it out. The rear blade is 12 inches long, but the factory blade was 10 inches, presumably to clear the roof camera. FYI the 12 inch blade works fine.

Easy Install and Skip Free
Size: 19"+18"+10"(U/J Hook)
This is a good kit - the second one I bought for a different car. Wipers seem to wipe ok. That is if you first remove the little blade guards that come with each wiper, just like the ice skaters use for their Olympic level blades. And having all three blades (two front and one back) ordered specifically to fit the car, I didn't have to guess and take multiple trips to AutoZone or Advance or O'Riellys. Sometimes the reviewer bot likes to know about some specifics as well. So . . . these fight a great battle to resist rain. And with a lever inside the car, these wipers are easy to use once installed. They are really fast when they slide out of the box. Having had some cars where the wipers fell off, I can attest to the safety that any wiper gives the driver, regardless of it's durability or speed. So I look forward to the safety these wipers will afford over having metal arms scratching across the windshield like fingernails on a chalk board.

Quality Wipers
Size: Combo Pack (23" & 19"), Style: Top Lock Narrow
These Bosch Aerotwin wipers are a perfect fit for my 2020 Audi Q5 and work exactly as expected. Installation was quick and straightforward, and they snapped right into place with no issues. They wipe smoothly and quietly, leaving the windshield crystal clear even during heavy rain. Performance feels very close to OEM quality—no streaking, no skipping, just consistent and reliable cleaning. They also hold up well at highway speeds without lifting or making noise. Overall, a great upgrade or replacement for the Q5. Highly recommend if you want dependable, factory-style performance without paying dealership prices.
