The SpeedFactory HD Detent Spring Kit fits all hydraulic DOHC B-Series (B16, B18, B20), cable (YS1 only), all K-Series, ONLY D16Y, F20B, F22A/B, H22A, and H23 transmissions.

We have been using these springs in our own transmission builds for years, and now you can too ! Add enjoyment to your driving experience with this simple to install and inexpensive upgrade that gives improved feel and shift action as you engage each gear.

The SpeedFactory HD Detent Spring Kit is a set of upgraded coil springs that increases the positive ratcheting feel of your transmission, with an over 80% increase in spring rate over the soft factory springs.

These spring kits are suitable for use in any car, street or track and are ideal for anyone desiring improved shifting feel.

Greatly improved tactile feedback/feel of each shift also helps ensure that the fork is fully in the desired gear position, and that it stays there.

Simple installation takes just minutes in the car:

1) Remove the OEM Spring Setting Bolts one at a time, taking care not to lose the OEM spring or ball.

2) Install the OEM ball, SpeedFactory HD Spring, and the OEM Spring Setting Bolt.

3) Torque Spring Setting Bolt to proper OEM specification (16 ft.- lb.)

4) Repeat this procedure to upgrade all detent springs in your transmission.

5) Enjoy crisper, more defined shifting!

Lifetime warranty against manufacturing defects.

Tough enough to take rough play.
Color: Multicolor A, Size: 2.0"(Small)-6 Pack
They are smaller than I thought. That’s on me because I didn’t see the size. My dog loves them anyway and they are sturdy

Lucy The Dog Approved!
It's really not for me to say, with exception of the orange-blue color, which is ideal for still life. But the best part is how unglued the Lucy Dog gets at the sound of the squeaky toy knowing the hall leading to my apartment is instantly converted into a Dog Run. And she gets equally excited at the sight of any grassy area when on bike rides. So a feature that is truly the dog's bollocks is it's the perfect size for both Lucy's petite mouth and the all important emergency spare that fits securely under my bike saddle. In short, sublime perfection in Lucy The Dog's expert opinion.

If you have dogs that like to play fetch, these are a must have!
Color: Orange - Pink, Size: 2.0"(Small)-4 Pack
My pups love these sp much, they won't play with any balls other than these. Not sure if it's the small size, or the fact that they squeek, but they def were a hit.

Fun balls for a small doggie
Our little Cockapoo loves these balls. When she can’t entice us to play, she has figured out how to bounce and chase a ball by herself - very cute!
