We designed the General-Purpose Rack (GPR) to be versatile, adaptable, and able to grow with your needs. The Alta GPR – 4 Pack has the same structure as the 5 pack and the 6 pack, making it super easy to grow the rack by just adding baskets. The only difference is the amount of baskets included. The GPR can accommodate 4, 5, and 6 baskets, and allows for infinite tie positions on the low bar so you can perfectly place your bikes every time, for every excursion. Every Alta Rack comes with black hardware and top/bottom bar with multiple color options for the Vertical Post. As a versatile and reliable rack that will meet all of your bike rack and storage needs, the GPR will get the job done. The Alta GPR – 4 Pack includes a total of 4 baskets, but additional baskets can be added in the selection below.

Safety & General Info:
For Alta GPR:
There is a max capacity of two E-bikes on a single GPR rack. If mounted, they must be loaded near the Vertical Post, close to the middle of the Top Bar.
Not ideal for Class-C RVs, Superior Rack models are much more suited for RVs, as they provide more rigidity for these types of vehicles
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.
Vehicle Requirements & Info:
All rack systems require a Class-3 hitch receiver with a minimum tongue weight of 500lbs.
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
