Do you work on trailers as well as trucks?

Yes. We repair trailers alongside trucks and RVs, including trailer brakes, suspension, lighting, body, and DOT inspections, all in one shop at I-70 Exit 28.

Can you fix trailer ABS and lighting faults?

Yes. We scan trailer ABS modules and trace lighting circuits, including bad grounds and chafed wiring that cause flickering or dead lights.

Do you do trailer DOT inspections?

Yes. We perform DOT-level inspections that catch out-of-service trailer items — brake stroke, lining, lights, and frame — before the scale does.

Can a tractor and trailer be fixed in the same trip?

Often, yes. Because we handle truck and trailer work under one roof, a combination that needs both can usually be done in one stop.

Do you repair trailer body and frame work?

Yes. We handle doors, floors, landing gear, and structural frame and cross-member work in the same shop as the mechanical repairs.

What is Trailer Repair?

Trailer repair is the service and structural work on the towed part of a combination — dry vans, reefers, flatbeds, and equipment trailers. The work spans the air brake system (chambers, slack adjusters, valves, lines), suspension (leaf springs, air ride, bushings, hubs), lighting and wiring, landing gear, doors and floors, and the frame and cross-members. A trailer has its own brake, ABS, and lighting systems that a truck-only shop can miss, and worn trailer parts are a top DOT out-of-service category.

Signs You Need It

Trailer brakes pull, grab, or fail the push-pull test
Air leaks that drop pressure overnight at the trailer
ABS or trailer brake warning light on the dash
Lights out, flickering, or a bad ground causing odd faults
Landing gear that won't crank or drops under load
Sagging suspension, cracked springs, or a leaning trailer
Doors that won't seal, a soft floor, or visible frame cracks

What Causes It?

Normal wear on brake friction, drums, and air system seals
Corrosion from road salt on frame, cross-members, and wiring
Air system moisture and oil from a failing dryer or compressor
Overloading or unbalanced loads stressing springs and frame
Chafed wiring and corroded connectors causing lighting faults
Impact damage from docks, curbs, and road debris

How We Perform Trailer Repair

Full trailer inspection: brakes, suspension, lights, frame, and floor

Air system leak-down and stroke check at every wheel end

ABS scan and lighting circuit test to find the real fault

Written estimate by axle and component before any work

Replace friction, drums, chambers, springs, and wiring as needed

Set brake stroke and verify all lights, then road test the combination

Can It Be Prevented?

Yes. Drain the trailer air tanks and keep the dryer serviced, check stroke at every PM, fix chafed wiring before it takes out a whole circuit, and wash salt off the frame and underbody. A trailer inspected on schedule rarely gets parked at the scale.

What Our Customers Say

"I went in there needing a break repair on my school bus that my wife and I had converted into a skoolie! After calling 5 other shops and getting either no response or getting told no, I called them and within 2 rings they answered the phone and got me the help I needed! If you have a semi or big engine needing repair I recommend this team! They're great at what they do, actually answer the phone, and will walk you through anything you may not understand without charging an unreasonable price!"

Local Guide

"There service dept. was fast and very courteous throughout the whole repair. They got my truck in and started right away with repairs. As a fleet owner this does not happen often to get service same day!!! When truck was not going to be completed on the same day, they allowed the driver to take the truck down to truck stop and come back the next morning to complete repairs. The biggest thing overall was, I was kept informed throughout the repair and that is my biggest complaint with most shops."
