Frequently Asked Questions About International LoneStar Frame Steps & Accessories

What gauge steel are these frame steps made from, and will they rust or corrode over time?

Most International LoneStar frame steps are constructed from heavy-duty 16-gauge steel with either a chrome-plated or powder-coated finish. Chrome options provide excellent corrosion resistance but require regular cleaning to maintain their shine, especially in winter climates with road salt. Powder-coated steps offer superior chip and scratch resistance but may show wear at mounting points after several years. For maximum longevity, we recommend applying a rust preventative to mounting hardware during installation and performing seasonal inspections of the finish.

Will these frame steps fit my specific International LoneStar model year, and are there differences between standard and extended cab versions?

Frame steps are typically compatible with International LoneStar models from 2008 to present, but there are important distinctions. Standard cab models use 3-step configurations measuring approximately 36-40 inches, while extended cab versions require 4-step units measuring 48-52 inches. The mounting bracket spacing also varies between pre-2015 and post-2015 models due to frame rail updates. Always verify your exact cab configuration and model year before ordering, as returns on incorrectly ordered steps often incur restocking fees.

How difficult is the installation process, and what tools or modifications are required?

Installation typically takes 2-3 hours per side for experienced mechanics and 4-5 hours for DIY installers. You'll need a drill with metal bits (typically 3/8" and 1/2"), a torque wrench, and basic hand tools. Most frame steps require drilling 4-6 holes per side into the frame rails. Pre-2015 models may need minor bracket modifications for proper alignment. Professional installation runs $200-400 depending on your location. Common challenges include accessing tight spaces behind the fuel tanks and ensuring proper ground clearance.

What's the actual weight capacity of these steps, and will they support heavy daily use?

Quality International LoneStar frame steps are tested to support 300-500 pounds per step, depending on the manufacturer. However, the effective weight capacity depends heavily on proper installation and frame mounting. Steps mounted with all recommended bolts and reinforcement plates maintain their rated capacity, while those with missing or loose hardware may fail at lower weights. For drivers over 250 pounds or those wearing heavy work boots, we recommend checking mounting bolt torque monthly and choosing steps with reinforced gussets at stress points.

What's the difference between the various finishes available, and which holds up best in different climates?

Chrome-plated steps offer the traditional semi-truck appearance but require monthly polishing in humid climates and weekly cleaning during winter salt exposure. Powder-coated black steps hide dirt better and resist chips but may fade in extreme sun exposure after 3-4 years. Stainless steel options cost 40-60% more but provide the best all-weather durability with minimal maintenance. For northern climates with heavy salt use, we recommend stainless or powder-coated options. For southern states, any finish works well with basic maintenance.
