K-Tuned released their original B/D shifter back in 2012. Since then they have released three different versions. They have also made some small changes to update the design over the years. Now, in 2019 K-Tuned has overhauled the three designs.

Starting at the bottom they have replaced the white plastic cage that holds the ball with a Delrin bushing. Delrin is used as it is one of the strongest plastics available, it is resistant to chemicals which is great for automotive applications. Delrin also has high abrasive resistance and low coefficient of friction which basically means it will shift smoothly when you first get it and for a long time. This will give you a tighter feel than the original accordion style plastic housing used on OEM shifters. The Delrin bushing is covered with a TPV bushing to keep it clean and anything from inside the bearing. K-Tuned has replaced the stamped steel base plate with a 0.35" aluminum plate which will be sturdier and not rust over time. This aluminum plate will also add to the rigidity and feel of the shifter. Since this is what holds the bearing assembly they have found the stock plate to have play, be rotted, or not even there if using new aftermarket linkage. K-Tuned has also added one more threaded hole to increase the rigidity further and triangulate the assembly. Now, this all wrapped around the redesigned lower shaft. K-Tuned has maintained the adjustable throw from their original shifter but made it adjustable from inside the car. The 6061 aluminum black anodized lower adjustment shaft is machined with notched section to make it easy to spin up or down to adjust the throw. They have machined a sight hole to make adjustment clear and easily measured using the numbered steel internal shaft.

The rest of the shifter will look familiar to K-Tuned's older designs they are sure you are familiar with. K-Tuned has anodized the elbows black and then machined logo and some edges for a clean and uniform look. All shifters are independently height and throw adjustable.

This Circuit X version carries over the extended height elbow from K-Tuned's  B/D pro circuit shifter model.

B/D-series Vehicle applications: 88-91 Civic/CRX, 92-00 Civic, 94-01 Integra

Fabrics Great, Size a little Big, Overall Pretty Good
Size: Medium, Color: Dark Navy
This suit was truly great, the size for the pants and the vest were pretty on point, maybe a little long for the pants. The jacket was way too big though compared to the rest. Overall pretty good suit for the price, very surprised at the build quality and faabrics.

Perfect Suit!
Size: 10, Color: Navy Blue-bowtie, Size: 10, Color: Navy Blue-bowtie
So cute! This slim suit fit my 9 yo son great! He’s 4’7 and 73lbs. He wore it to perform in his school’s talent show and again at Easter. We got tons of compliments both times! It’s a good quality, not cheap materials, and he said it was comfortable (he wore it for hours each time). Love, love, love this cute suit!
