What's actually new in the 'Mark V' version versus older LHR15 models?

RUPES's own product page credits the update to POLYSYNTHEC composite gears (lighter, less lubrication-dependent than the metal gears in earlier LHR15 generations), which the company says reduces vibration and noise and improves motor efficiency. The backing pad size (125mm) and 15mm orbit carry over from prior generations.

Does the tool-only listing include a backing pad?

Yes, the ASIN we verified includes one PrecisionPro backing plate, per both the Amazon listing title and RUPES's own kit breakdown. It does not include polishing pads or compound.

RUPES's BigFoot line is the machine professional detailers reach for, and the Mark V update trims noise and vibration without changing what made the LHR15 a category benchmark.

RUPES BigFoot LHR15 Mark V: What to Know

The LHR15 Mark V is a corded random-orbital polisher built around a 15mm orbit and a 125mm (5-inch) PrecisionPro backing plate, a bigger throw than any other machine in this lineup, which is what lets it remove moderate swirls and light oxidation faster than a typical beginner DA tool. RUPES rates the Mark V's update around POLYSYNTHEC composite gears in place of metal ones, which the company says cuts vibration and noise versus the prior Mark III/ES generation while needing less lubrication over the tool's life. Third-party detailing retailers list a working speed range of roughly 3,000-5,200 RPM and a bare weight around 5.7 lb, figures RUPES itself doesn't spell out on its own product page, we're flagging that gap rather than guessing at a number RUPES hasn't published directly.

The Amazon listing we verified (ASIN B0DQC4MMPD) is the tool-only configuration, which ships with the polisher and a PrecisionPro backing plate but no pads or compound; RUPES and various detailing shops also sell it in Starter and Complete kit bundles under different ASINs if you'd rather not buy pads separately. At $500+ list, this is priced well above the other four machines here, and that premium buys you a heavier-duty motor and the anti-spinning ring RUPES added specifically to keep the pad from free-spinning against a panel edge, a small but real safety-relevant feature for anyone working around trim and body lines.

Because it's still a random-orbital (not rotary) tool, the LHR15 Mark V carries the same forgiving-to-beginners behavior as the other polishers in this guide, the pad won't burn through clear coat from dwelling in one spot the way a rotary buffer can. That said, its larger 15mm orbit and stronger motor mean it removes material faster than a lighter DA polisher, so it rewards (rather than requires) some prior polishing experience.
