What We
Do

01

Fleet Maintenance

Scheduled servicing that keeps trucks road-ready — oil, filters, greasing, fluids and wear checks across your whole fleet.

02

Truck & Trailer Repairs

Engine, driveline, brake, suspension and body work on trucks and trailers of every make.

03

ABS

ABS and trailer-light diagnostics, wheel-speed sensors, harness repairs and fault clearing.

04

Farm Equipment & Forklifts

If it's heavy and it's broken, bring it in — tractors, loaders, forklifts, yard trucks and other farm equipment.

05

Paint & Restoration

Rust repair, bodywork, primer and paint, chrome and trim refresh, and bringing older trucks and trailers back to clean road condition.

06

Trouble Code Diagnosis

We pull the fault codes, trace what is actually causing them and fix the root problem — not just clear the code and send you down the road.

07

Custom Light Bars & LED Lighting

Light bars and LED upgrades for trucks, trailers and equipment — headlight conversions, marker and work lighting, mounted and wired properly.

08

Welding

Custom metal fabrication on site — protection bars, cattle guards, light bars, headache racks, aluminum and stainless, MIG, TIG or arc.
