DALTON DALTON HELIX POLARIS TP21 56/42 PER TP21 56_42 PER

2021+ Polaris Large-Roller TSS-04 Team Secondary – TP21 Series

Helixes for 2021 and newer Polaris “large roller” Team secondary.

For the 2021 model year Polaris models have gone to a new “large roller” secondary.

The helixes we have for this secondary are designated “TP21” and these helixes are only for this clutch version. The helixes from previous model years cannot be used in this secondary with its larger diameter rollers.

It is important to realize what the helix numbers designate. We offer both "compound" and "progressive" style.

All of the TP21 models we cut are for Electronic Reverse 2-stroke engine models, and have the reverse notch (we do not build without the notch).

All Dalton helixes for this clutch use the “TP21” designation. Compound curves read as start angle / finish angle / transition length; “P” identifies a progressive curve and “ER” identifies electronic reverse, e.g. (TP21-46 / 42 / 36 ER) or (TP21-44 / 40 P ER).
