North Fontana is one of Fontana's most active areas for truck owners, with 72,000 residents near Sierra Ave and I-15 Freeway.

We proudly offer LINE-X and other top-name brands, all backed by manufacturer warranties.

The I-10/I-15 interchange in Fontana is one of the highest-volume freight nexuses in the United States, with commercial trucks comprising 18–22% of daily traffic. BNSF's San Bernardino intermodal facility, Amazon and Skechers distribution centers, and Kaiser Steel's industrial legacy mean Fontana's 92335 zip has one of the highest concentrations of work trucks in San Bernardino County — trucks that need bed protection from daily abuse, not occasional use.
Fontana averages 284 sunny days per year with July and August highs of 105–112°F and UV index 10–11. Extreme heat accelerates bed degradation; asphalt and concrete dust from Fontana's industrial zones compound surface abrasion. LINE-X outlasts factory paint and plastic liners under these conditions.
North Fontana's motorsports culture — anchored by Auto Club Speedway and the Sierra Ave corridor — means truck owners here take builds seriously. Whether you're running tools to a job site or gear to the track, Fontana residents choose LINE-X for durability that matches the way they use their trucks.

We serve these nearby locations for suspension upgrade:
“Had Bilstein 5100s installed front and rear on my 4Runner. The difference in ride quality on the highway is night and day. Empire's guys know suspension — they explained exactly why they recommended the specific valving for my setup.”
“I came in with sagging rear springs on a heavily loaded work truck. Ryan diagnosed it in 5 minutes and had me sorted with new Rough Country add-a-leafs the same day. Back to riding level and hauling without bottoming out.”
“Jake did the Fox suspension build on my Tacoma and it's transformed the truck. Incredible off-road capability and way better on-road comfort. Worth every dollar.”
