The solid steel construction and zinc plating of the Stabilizer System ensure a life long performance and includes all Grade-8 hardware. The stabilizer system boasts three thread locations, providing ultimate adjustability for the distance of the rack from the vehicle.

  • The Internal Stabilizer block installs inside of the hitch, and utilizes an included 5/8-inch bolt and locking washer, effectively stopping all horizontal movements.
  • The External Stabilizer installs outside of the hitch and receiver, and prevents all vertical movement, featuring a low profile and easy assembly with a single 3/8-inch bolt

This combined system provides the most secure stabilization for a worry-free and movement-free rack experience.

    Had to get a replacement because my first one bent. Is strong but unfortunately when you’re applying it to a 6k+ lbs vehicle and the road, it can take a beating and become deformed. Overall, good product.

  11. Timothy P. (verified owner)

    This is fantastic, huge improvement on the original stabilizer. Our OG Alta Rack is now rock solid, even with two e-bikes. Great design!

    External Stabilizer
    Pros: works as intended – does stabilize the hitch; single bolt design (others use two bolts); price is on-par with other systems
    Cons: the bolt cuts into the hitch (chipping paint and increasing the rust factor of the hitch); bolt does work loose and needs to be tightened every so often;

    • altaracks (store manager)

      Thanks for your review mark, we do use tension for tightening the external, the bolt can be pressed against the receiver as well. Depending on the sturdiness of the vehicle receiver the external stabilizer can come loose if the receiver is flexing.

    These things are great, keeps the receiver from moving. That is key when it’s on the back of he camper.

* On an HD Basket w/ E-Bike Straps 

Bike Straps – Each Rack comes with 2 custom straps per included basket, one to secure the front wheel to the basket, and one to secure the back wheel to the bottom bar

OSP (Outer Safety Pin) – The OSP adds an extra measure of safety to secure the system in place, and allows for the rack to tilt away from the hitch when removed for easy loading and unloading

Tensioner – The adjustable tensioner bolt allows for more or less space for the rack to tilt back. Higher tension equals slower tilt, and lower tension equals faster tilt. We recommend adjusting toward the tighter side for heavier loads

Hitch – Each Alta Rack comes with a hitch to attach to your vehicle. Non-Superior Racks come with a General Hitch and Superior Racks come with an XL Hitch by default. However, you can switch these hitches out depending on your clearance needs

Baskets – Every Alta Rack includes a set number of baskets that cradle the front wheel of your bikes. They can be switched out for different sizes and moved around for more or less space by loosening or tightening the basket knobs below

E-Bike Straps – E-Bike straps are not included in most racks, but are highly recommended for all bike types (especially heavier E-bikes) for a higher weight capacity per basket. They strap on to your bike pedals to put less weight in the basket and more on the top bar

Retractable Straps – Two Retractable Straps come with every Superior Rack for added stability and security for your bikes. We recommend tying down the straps directly to your vehicle (not to the hitch) placed high or low (top or bottom of your vehicle), and angled wide

Low Bar – The Low Bar is an integral part of each rack system, providing limitless positioning for rear bike wheels. The straps on the low bar allow for any wheel size to fit snugly during transport

Gussets – Unique to the Alta Superior Rack, the Gussets extend from the bottom of the vertical post to the ends of the top bar, providing greater support, rigidity, and weight capacity

Gear Hanger – This accessory lets you hang helmets, water bottles, camel backs, and other gear directly on the rack. It is purchased separately and is a great addition for storage on your Alta Rack system

Brake Engagers – Two brake engagers are included with each basket and are generally stored on the basket knobs. These attach directly to your bike brakes to engage them and prevent your bike wheels from moving, creating less movement during transport

Main Beam – The main beam is the core of each Alta Rack. Even after switching out top and bottom bars, baskets, or hitches, it is the part that stays with you to the very end. Comes in awesome colors, too

Top Bar – The long bar that extends from the main beam at the top. It carries all your baskets and is a big player in how we customize our racks. The simple, yet robust design allows for limitless modularity with baskets, accessories, and mounts
