Important Information (Please Read):

Safety & General Info:
  • For all Alta Racks:
    • Do not exceed max weight capacity for both the rack and the baskets, not even by a pound. A good rule to follow is loading 10% below max weight capacity (see Alta Rack comparison table for weight capacity)
    • Off-road and rough-road driving places significant forces on the rack. Tying down the rack (with retractable straps or tie-downs) and utilizing the brake engagers on your bike brakes (included with each rack) are key to create a stable system, especially when off-roading and rough-roading
      • Tie Down Instructions: Tie down from the ends of the Top Bar to a high/low and wide location on the vehicle. Ensure the straps are taught and that the weight of the rack is pulled forward toward the vehicle. Do not attach the tie downs to the hitch. They must be attached directly to the body of the vehicle
    • Tie down system is 100% required for RVs, longer XL vehicles (Sprinters, and similar vehicles), and anything with stiff rear suspension. However, we highly recommend using tie downs on all vehicles to mitigate play and secure the system tightly to the vehicle
    • We do not recommend using an Alta Rack on any third-party swing out, as they may create significant play, and do not provide an effective way to tighten the rack. These issues will bend baskets, which is not covered by our lifetime warranty. Using swing outs that aren’t specifically engineered for our racks is predominately discouraged due to an insufficient transfer of force from the bike rack to the vehicle (which greatly increases play and wobble) as well as their lower weight capacity.
    • ALL E bikes must utilize E bike straps and the correct rated baskets. You will bend the basket if you dont use E bike straps, its ideal to remove the battery from the bike if possible for better carry experience.
Vehicle Requirements & Info:
  • All rack systems require a Class-3 hitch receiver with a minimum tongue weight of 500lbs.
  • For double-door vans, utilize tie down to door hinges. See off-roading videos for setup
  • For trucks, we recommend the XL Hitch for clearing tailgates, on new Ford, Dodge, Chevy Colorado, Ford Ranger, and Toyota Tundra trucks. The Toyota Tacoma will work with a regular hitch

    • Shipping is flat-rate and is based on country
    • Custom powder coat available for all parts September to April

  1. Philip (verified owner) –

    Solid construction . Works well on Ram Promaster 2500

  2. Chris Kasel –

    Selected this rack because of its capabilities to carry 4 e-bikes if necessary. Also the offset design works awesome on my Ram Promaster allowing the passenger side rear door to fully open when the rack is tilted back. Just got back from a 2400 mile road trip and the rack was very stable and the bikes didn’t rub on each other. Highly recommend it!

  3. Sam P. –

    This rack is amazing. I looked at all the options for a vertical rack, and when I did my homework, there was nothing that came close to the quality of the Alta. I would unequivocally recommend this rack to anyone who’s thinking about buying.

  5. Pete Whitehead (verified owner) –

    Extremely satisfied. Solid rack with no movement on our truck during our off-road adventures in Moab. Best rack on the market.

  6. Anonymous (verified owner) –

    Very well made rack strong and heavy. Goes together easy shipping was fast and berry well packed. I would like to see more options on the web site for colors on other parts of the rack beside the single post, baskets, bottom bracket, brace, etc. The “made in USA” sticker on the hitch was placed crooked. I would have thought with the price tag the attention to detail would be better. It would be nice to Provide locktight for the 4 bolts that do not have the nylocks and the large bolt with plastic wrapped around it as these cannot be over tight due to deflection and not everyone has a torque wrench.
    Overall a great rack

  7. john n. (verified owner) –

    Easy to assemble – arrived well ahead of promised. It is a great rack – works on the Earthcruiser – perfect fit.

  8. Micki Smith (verified owner) –

    Love the rack, but the ebike straps seems to be too long to work on my bikes. I have a large and a small. Maybe I’m not using them correctly, but I watched the video – – and think I understood. Any help would be appreciated. Thanks, Micki

  9. Will S. (verified owner) –

    Best way I have carried four bikes. Still having plenty of access to the trunk is a game changer!

* 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
