Twin Cam Tire Shredder Kit - 103CI to 110CI is rated 4.2 out of 5 by 9.
Rated 3 out of 5 by from Wouldn't do it again I had this kit installed on an 09 road king. It came out at 112 hp and 116 torque. I was hoping for a lil more since the price seemed to go up more as they got into the build. It's definitely more fun then stock. But for what I ended up spending I could have gotten more going to a custom cycle shop. Nothing was ever said to me about bringing it back in for a final tune after 1000 miles though.

Rated 4 out of 5 by from Good bang for the buck! I had this installed on my 09 Ultra. I am really happy with the added performance. It is like adding another cylinder. After reading the other reviews, I need to redyno. My 09 came out with 110 ft. lbs of torque, and 109hp. I was also pleased there weren't lot of hidden costs. Great addition to my favorite toy.

Rated 5 out of 5 by from Tire Shredder I installed this on my 15' FLTRXS. It was worth every buck. I also am using the SE Race Tuner and the Elite Breather air filter set up.. After about 500 miles I dyno'd it and it is on a conservative map until the motor is completely broken in. 115.1 hp and 121.9 torque at about 5600 rpms! Once broken in I will remap it and give it a little more. Roll out of the hole and knuckle it and it spins the tire and lifts the front end off the ground shifting into second gear. This kit also changes the exhaust tone to a deep thumping. I am running with S&S head pipes with Rinehart slip ons. The only negative is the range dropped about 40 miles to a tank of fuel but with 115 horse it makes up for the loss in range.

Rated 5 out of 5 by from power and compression The power and compression on the bike now is refreshing. I was coming off a 113ci. I missed some of that power. Now it feels really nice. I'm much happier with my bike. I'm still at break-in miles, so I can't even really get on it aggressively. But I'm telling you its already a large improvement from the HO103. My exhaust sounds tons throatier. too. I will have to check my mpg over time. I'm sure it will have gone down some. But worth it to me to have the torque and horsepower I was accustomed to.

Throttle Body that comes with kit.

Part list says this kit is using (58 mm ETC throttle body kit 27713-08) Are we sure this is the correct part number? Fitment for the above listed part number is Fits ’16-later Softail and ’11-later CVO Softail and ’08-’13 Touring models. but this kit says it should fit my 2016 Touring. I am a bit confused. Can you clarify. Thank you

110 tire shredder kit.

I got a 16 road glide. Had a few problems so the guy at the he shop said I needed a few things so figured I’d mine as while upgrade the bike and put the 110 tire shrewder kit on my 103. Was woundein when it’s all done is there going to be a screaming eagle 110 badge on the heads like the CVO have? Or there’s no badging? Nothing will say 110? Thanks.

If i put the 110 ttire shredder kit on my 2015 Are the heads still going to be water cooled STILL


Will this kit fit a 2016 FXSB Breakout

The fitment suggests not, but having looked at the actual components between this and other big bore kits that do officials say they support the breakout (i.e. 92500011), I can't understand why they won't work. The parts list are almost identical except that this tire shredder kit includes; CNC ported heads and no ACR larger throttle body / injectors different exhaust port gasket different perfect pushrods different head gasket Having spoken to my UK dealer, they are saying as the online shop doesn't say it fits, they won't supply and fit it and they won't ask the question of you guys. They response doesn't make sense as they will happily supply and fit SE 259E cams even though your online site doesn't show them as fitment for the breakout - despite the deal fitting them to many other breakouts in the past. So, accepting that your shop isn't always accurate on what bikes parts will fit, could you let me know if this kit will fit the FXSB breakout and if not, what part is the reason it won't fit. cheers Gary
Asked by: GaryP

Will this fit earlier 103?

I have a 2011 FLHTP- will this kit go on it too? If not, what is different?
Asked by: TheFasterGun
According to the application it will. Check with your local dealer to make sure.
