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.

Kids?
Size: Medium, Color: (025) Castlerock / Castlerock / Anthracite
I didn’t realize these were kids socks, until after I got them, but the fit is amazing and they stay put, without coming off my heels. I wear an 8.5-9 in women’s shoes.

Favorite Socks Ever
Size: Medium, Color: Black/Assorted, Size: Medium, Color: Black/Assorted
I absolutely love these socks, they compress in the middle which is my favorite thing about them! Keeps them from slipping off my feet and also adds support, love love love how they feel and how long they last! This is my second pack that I’ve purchased, I had the multi colored ones before and they’ve lasted me two years before finally starting to wear out and fade and get holes. Definitely going to be routinely buying these every year. Good to wear with my work out shoes...winter boots, Nike sandals, and my everyday adidas sneakers. These are so worth it!

Great ankle socks that stay put at a great price!!
Size: 6-9, Color: Assorted
These are great! I have been looking for a low profile ankle sock that is thinner but doesn’t ride down. (Picky, right?) I try to walk 5-7 miles on my days off. So it’s very important for me to not have to stop every couple of hundred yards, bend down, fix socks, then continue on my way while grumbling about NOT GREAT socks. These are not those socks. They really do stay put!!! And enough cushion to be comfortable also. So definitely a repeat!!
