Service Questions & Answers

Are body height and length modifications kept within RTO limits?

Yes. We advise and fabricate strictly within permissible chassis overhang and height norms so you avoid highway compliance issues.

Can you convert or adapt an open pickup body with extra side height and roof carrier?

Yes, LCV/pickup height extensions, overhead carrier racks, and side-gate conversions are regularly done at our workshop.

Will extending a body weaken the existing frame?

No. We reinforce the extension points with matching channel sections and gusset plates so load distribution stays balanced.
