3″ ProFlow Boost Tube & boot


Brand: ProFab Performance
Availability: In Stock

SKU: dmlly-lmmsbt Categories: , ,


This 3″ boost tube is for use ONLY with our LLY- LBZ – LMM shorty bridge.

It runs over the alternator and in front of the motor making it ideal for use with twins and big singles.

It gives a significant flow increase and comes powder coated black & includes the upper hose and clamps. The LLY install requires some tweaking on the coolant and trans lines in front of the motor. It also requires the 90b-300 x 10 lower elbow and 2 clamps and can be added below.

NEW Product!! We now have these for the LBZ – LMM that go behind and beside the alternator in a more stock location. Make that selection below.
