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.

Best socks for work or working out.
Size: One Size, Color: (015) Tetra Gray / Gray Matter / White Quartz
Great socks. They stay on your heel! Love the material; breathable and not thick. Love the neutral tone colors.

Perfect thickness and soft feel.
Size: 6-10, Color: Halo Gray/Assorted
Why did you pick this product vs others?:
Love theses socks. It's hard to find socks which won't get pulled down by athletic shoes. These stay put.

Comfy, great quality
Size: 6-10, Color: White
I’ve had these for quite a while now. They are holding up very well as i wear them a lot for work (coaching). They are very cushiony and most importantly, they do not slip!
I would compare these to Bombas but at a significantly better price point.

My favorite socks now!
Size: Medium, Color: Deep Sea/Breaker Blue/Electro Pink
I love socks! And these are quickly becoming my favorites! They do not slide down into your shoe no matter if you are working out or just wearing them for normal everyday use. The price is a little higher than I would normally pay for 3 pair of socks, but after wearing these for a few weeks, I think the quality and comfortability of these socks is well worth the money.
