Piston ring compressors for British Twins

Regular price $37.16 $0.00

Piston rings have a hard enough time without getting beat up during installation. If you have a 2 or 3 piece oil ring you MUST use ring compressors to prevent damage to the ring. It also makes putting your cylinder on easier and almost effortless.

Don't break a ring during installation! Most rings are only sold in sets!

For 650 Triumph twins use the 70-75mm ring compressors.

For 750 Triumph twins and big bore kits use the 75-80mm ring compressors.

For unit 500 pistons use 65-70mm ring compressors.

For Pre Unit 500 use 60-65mm ring compressors.

60mm - 65mm = 2.36" - 2.55"

65mm - 70mm = 2.55" - 2.75"

70mm - 75mm = 2.75" - 2.95"

75mm - 80mm = 2.95" - 3.14"

These are sold in pairs, and were imported from England.
