1.5” BDL Primaries for 4 speeds

I’ve been using 1.5” BDL primaries on my builds for over a decade. 
These units are the best size and combination for all around riding and dependability.

The shaved and polished clutch basket paired with our heavy duty billet 4 speed primary kits make for a unique and stylish primary that functions better than it looks. 

Available as a complete primary (primary, hub, plates, springs), with or without our 4 speed kit, as well as on their own so you can use your stock hub, plates, and springs.  

Or send us your clutch basket to have it shaved and polished.

*These units come direct from BDL before we work our magic in house and require a 2-3 week leadtime
