The 2020 BRP 900T uses the same clutching as the 2019 900T with the exception of the secondary spring. The 2020 uses a compression spring instead of a torsional spring like the 2019 ACE. The Hurricane Torsional Upgrade kit includes an easy to use jig to drill the stock 2020 helix to fit the quality Dalton torsional spring.
