Downtown Chino is one of Chino's most active areas for truck owners, with 35,000 residents near Chino Airport and Central Ave. Downtown Chino has a strong working-truck culture with many contractors and tradespeople who rely on their vehicles daily. We specialize in LINE-X spray-on bed liners and protective coatings, along with a full range of truck accessories, including bed covers, side steps, running boards, toolboxes, contractor racks, and more. We proudly offer LINE-X and other top-name brands, all backed by manufacturer warranties. Our 10,000 sq. ft. facility at 9261 Bally Ct in Rancho Cucamonga is about 15 minutes from Downtown Chino — close enough for a same-day appointment on most quality drivetrain & differential service jobs.
Pricing for drivetrain & differential service in Chino typically runs $250–$3,500 depending on your vehicle make, model, and selected options. We provide a free, no-obligation quote before any work begins.
Chino sits between Chino Airport, SR-71, and the Chino Hills State Park corridor — a mix of aviation industry workers, warehouse operators, and tradespeople who depend on trucks daily. The BNSF intermodal network and distribution centers along the I-60 corridor mean Chino residents disproportionately own work trucks subject to pallet damage, gravel loads, and repeated cargo cycles that destroy unprotected beds within months.
Chino falls within the South Coast Air Quality Management District, where spray-applied bed coatings must meet strict VOC limits under SCAQMD Rule 1107. LINE-X polyurea formulations are engineered for California compliance — a meaningful differentiator when choosing an authorized installer over an unpermitted shop. Combined with 105°F+ summer heat and extreme UV, professional spray-on protection is the practical choice for long-term bed durability.
Many Chino truck owners split time between weekday job sites and weekend runs toward Chino Hills State Park. That dual-use pattern — tools and lumber Monday through Friday, bikes and camping gear on Saturday — is exactly why a permanent LINE-X liner outperforms drop-in alternatives that shift under load.

Do I need to re-gear after installing larger tires?
Going up two or more tire sizes typically requires re-gearing to restore performance. We'll check your current ratio and recommend the right gear for your tire size and driving style. Our shop at 9261 Bally Ct, Rancho Cucamonga is about 8 miles from Chino — most customers are in and out the same day.
What's the difference between a locker and a limited-slip?
A limited-slip transfers some power to the wheel with traction. A locker fully locks both wheels together for maximum traction. Lockers are stronger off-road; limited-slips are easier on pavement.
How long does a gear change take?
A full re-gear of front and rear axles takes a full day. We do the work, set up the gear pattern, and put break-in oil in. You drive carefully for the first 500 miles, then return for an oil change.
We serve these nearby locations for drivetrain & differential service:
“Floyd re-geared my Jeep from 3.73s to 4.88s after going to 37-inch tires. The pattern setup was spot on — quiet at highway speed and no backlash. He walked me through the break-in procedure before I left. These guys know diffs.”
“Had an ARB Air Locker installed in the rear axle of my 4Runner. Jake did the work and tested the locker at pressure before I drove off. It engages and disengages perfectly. Excellent technical work.”
“Empire diagnosed a clunk in my driveshaft as a worn slip yoke and had it sorted same day. Fair pricing and they caught the issue instead of upselling me on a full drivetrain rebuild. Honest shop.”
