POWER HOUSE 6 SPEED TRANSMISSION CONVERSION BUILDERS KIT FOR HARLEY BIG TWIN
Part # 72731
IN STOCK & READY TO SHIP
Fits 90-06 Big Twin models
Instructions included w/purchase & available online on the Ultima website
The Ultima Six Speed Builders kit was designed to provide a simple, low cost, 6 speed overdrive solution for 1990-2006 Big twin owners.
These kits work in most 1990-1999 models with little or no modification. A speedometer recalibration unit is required on some 1996-2000 and all 2001-Later models. These kits will work in 5 spd type 2000-Later models with additional minor modifications. The trap door is thicker than stock so any brackets used that are trap door mounted may need modification. All Touring FLT and FLH Models 1993-Later require an oil filler spacer #89-14, sold separately.

Great but hard to see when playing!
Style: 6 - Pack, Color: Purple
The balls are great but when playing with them, if you wear glasses the ball is a little hard to see. We played with the orange, yellow and green balls, which are easier on the eyes. Otherwise, the balls are great! 😍

Great value
Style: 6 - Pack, Color: Purple
Although pickle ball snobs have told me these are NOT proper outdoor balls, I love them! Not only are they a fantastic color but I like the weight of them and they are great for outdoor play. As a bonus, they are well-priced, so I feel I got bang for my buck.

Bright color easy to see but not a great bounce on the outdoor court
Style: 6 - Pack, Color: Pink
I liked the fact that these balls were a bright color and easy to see but the bounce on them was not as good as other name brands. They were OK as a back-up and performed better outside then on the indoor courts which are made of a different surface. We are using them , but would most likely not repurchase.

Price was best I found for quantity anywhere
Style: 6 - Pack, Color: Purple
I am a beginner and by no means an expert, but these balls appear to be as any other. The couple at the next court had a Franklin ball that came our way, and I bounced it and popped it back - I couldn't tell any difference in that instance. Sports stores had just one color - yellow (maybe one had chartreuse) amazon has single colors multiple - I thought it was worth this purchase. The purple may be harder to see on cloudy days - as I had on sunglasses and I could see it, but the fence at the court has a "privacy" net, it kinda bleneded in for a very brief moment until the sound was heard of the return, then no problem.
