The RUPES BigFoot LHR21 Mark V is the ultimate long-throw random orbital polisher for detailers looking to maximize correction speed on large vehicles and expansive panels. Featuring a massive 21mm orbit, newly engineered POLYSYNTHEC gears, PrecisionPro backing plate technology, and improved ergonomics, the Mark V delivers faster correction, smoother operation, and exceptional finishing performance on all paint systems.

Key Features & Benefits

21mm Orbit for Maximum Efficiency The large 21mm throw covers more surface area with each pass, dramatically reducing correction time on hoods, roofs, doors, trucks, SUVs, RVs, and boats.

New POLYSYNTHEC Gear System Advanced composite gears reduce vibration and noise while improving efficiency and durability for a smoother polishing experience.

PrecisionPro Backing Plate Technology Provides improved balance, control, and safety while reducing the risk of accidental contact on sensitive surfaces.

Lower Center of Gravity Design The Mark V’s center of gravity is 13mm lower than previous generations, improving stability and precision during correction work.

47% Noise Reduction Compared to Previous Models One of the quietest professional polishers on the market, helping reduce operator fatigue during long polishing sessions.

Improved Ergonomics & Operator Comfort Redesigned grip zones, progressive trigger control, and reduced vibration make the Mark V more comfortable for all-day use.

Ideal for Large Vehicle Correction The preferred choice for professional detailers working on trucks, SUVs, RVs, boats, and large passenger vehicles.

How To Use

Step 1:

Wash, decontaminate, and dry the vehicle thoroughly.

Step 2:

Install the appropriate 6″ backing plate pad combination based on the level of correction required.

Step 3:

Apply compound or polish evenly to the pad.

Step 4:

Spread product at a lower speed setting before increasing speed for correction.

Step 5:

Use slow overlapping passes while maintaining pad rotation and consistent pressure.

Step 6:

Wipe away residue and inspect results before moving to a finishing step if needed.

Pro Tip:

The LHR21 Mark V excels on large flat panels. Pair it with RUPES D-A Coarse Compound and a Blue Wool Pad for rapid defect removal, then finish with D-A Fine Compound and a Yellow Foam Pad for incredible gloss and clarity.

Why We Love It

At Car Supplies Warehouse, we love the LHR21 Mark V because nothing covers ground faster while still delivering the smoothness and finish quality that made the BigFoot system famous. If you’re regularly correcting trucks, SUVs, boats, RVs, or larger vehicles, the 21mm orbit can dramatically reduce polishing time compared to smaller orbit machines. The Mark V improvements make this already legendary machine quieter, smoother, and more comfortable than ever before.

Frequently Asked Questions

What is the difference between the LHR15 Mark V and LHR21 Mark V?

The LHR21 Mark V uses a larger 21mm orbit that covers more surface area per pass, making it ideal for large vehicles and panels. The LHR15 Mark V offers slightly more versatility on tighter curves and smaller vehicles.

What size pads does the LHR21 Mark V use?

The machine features a 150mm (6″) backing plate and is designed to work with 6″ and 6.5″ polishing pads.

Is the LHR21 Mark V beginner-friendly?

Yes. Despite its large orbit, the random orbital movement makes it significantly safer and easier to use than a rotary polisher while delivering professional-level correction results.

What types of vehicles benefit most from a 21mm polisher?

Trucks, SUVs, RVs, boats, and larger passenger vehicles benefit the most because the larger orbit allows you to correct paint faster over expansive surfaces.
