Trailer Lift Gate, Suspension, & Bodywork Services

Whether you need your lift gates serviced, your trailer's suspension rebuilt, or bodywork to make your trailer like new again, trust the professionals at Grand National Trailer for complete trailer services. We make sure to complete every project correctly the first time and provide you with competitive prices.

Preventative Maintenance For Lift Gates

Having the lift gates on your trailers serviced on a regular basis saves you money and time in the long run. We change the hydraulic fluid, check all the wiring for the hydraulic hoses to make sure there is no fraying, and grease the lift gate in the course of this one-hour service.

Suspension Checks & Rebuilds

Everything rides on your suspension, so it's critical that it is well-maintained and in good working order. Our team checks the airbags to ensure they are not rotten as well as performs suspension sub-frame rebuilds. If needed, we can fabricate a like-new sub-frame for you and slide it back in place under the trailer. Sub-frame rebuilds take 2 to 3 days.
