DIAMOND PISTONS · SPECIAL ORDER
Volkswagen Golf R32 VR6 forged piston kit
Build a Volkswagen Golf R32 VR6 rotating assembly around a Diamond six-piston kit. The -22.00 cc crown is offered in two finished bore sizes, with standard or upgraded H13 gudgeon pins included at the selected price.
Made to order. Allow approximately 5–6 weeks for delivery, pending Australian customs processing time.
Precision in the details
- 2618 forged aluminium with a full-round forging profile.
- Oil-ring-fed pin lubrication and fitted gudgeon pins.
- Side gas ports and moly-coated skirts.
- 3D-machined crown and valve-pocket profiles.
- The specified ring set, pins and retainers are included in the kit price.
Choose your specification
Choose an 84.00 mm bore with a 9.00:1 nominal ratio or an 84.50 mm bore with a 9.10:1 nominal ratio. Both use a -22.00 cc crown. Select standard G-series or H13 gudgeon pins; the displayed price includes the selected pin kit.

Fitment and engine preparation
For Volkswagen Golf Mk5 R32 VR6 engine builds using a 95.90 mm crank stroke, 6.457 in connecting rods and 1.364 in piston compression height. Confirm the engine code, cylinder-head geometry and measured rotating assembly. These dimensions do not establish fitment to other VR6 capacities or crank-and-rod combinations.
Catalogue bores are finished cylinder-bore sizes. Nominal compression ratios depend on the measured chamber volume, deck clearance and compressed head-gasket thickness. Use the instructions supplied with your exact kit for piston-to-wall clearance, ring end gaps and pin fit; confirm all machining and assembly dimensions with your engine builder.
