Isuzu D-Max Underseal & Chassis Repair
Farmers and tradesmen across Ireland rely on the Isuzu D-Max for its toughness, but the ladder chassis and rear leaf spring mounts still suffer in wet fields and salted roads. We strip back corrosion, weld where the chassis is compromised, then apply premium heavy-duty underseal with up to a 7 year warranty.
Common Isuzu D-Max rust hotspots we treat
Years on Irish roads, salt and damp wear down even the toughest Isuzu D-Max chassis. These are the areas we strip, weld and re-seal every week.
- Rear chassis rails behind the cab
- Rear leaf spring hangers and shackle mounts
- Front chassis crossmember behind the bumper
- Sills and cab floor edges
- Rear crossmember and tow hitch mount
- Load bay floor and tailgate hinge mounts
