Gear-X components are absolutely the best of the best, in their line of products. The value is incredible and the materials, machining and quality of these gears and final drives is unsurpassed. You won't find a better quality product for the price anywhere. Manufactured from the finest forged chromoly steel and machined to exact tolerances, these gears will out perform and outlast any competing brands on the market. Designed for racing, tested and sold by racers!

The Gear-X Close Ratio Gear Set for the K-Series engine is designed as a drop-in replacement kit for up to 500hp.

Suitable for street and race K20 or K24 where very close ratio applications are required, such sprints, hill climbs, road race and drag race. Works well with a factory final drive, but is a spectacular performer when used with a 5.08 final drive. When a 5.46 final drive is used with this gear set, it is designed for very short-course racing or fast, short, autocross courses. It is not suggested using the 5.84 or 6.33 final drives with this close-ratio gearset.

      Beloved But Beware Microplastic Chip-Offs
      Color: Bacon
      My doodle adores this thing and gnaws on it constantly. He has not been able to harm it, which is great. That’s the best part. Things to be aware of: 1. This is mostly molded plastic; it is a bit heavy and very hard. My dog tosses it into the air and if it lands on him, it HURTS. A lot. 2. While it’s sturdy, sharp teeth eventually gnaw pieces and little shavings off the toy. These are microplastics and could be harmful if your dog swallows them.

      Long lasting and safer alternative to sticks
      Color: Dogwood & Calming, Size: Medium
      These are great, very durable, and have lasted a very long time. Much safer for my dogs than the random sticks they find in the yard. They do get shorter with chewing eventually, but they don't break off in little chunks like I've seen with some nylon chews, and they don't splinter like wood. Medium size works well for both my 16 lb Cavalier and my 60 lb Pyrenees/Golden mix. They're both moderate-to-aggressive chewers, though size obviously affects how much damage they can do. I wish you could buy the hemp chew separately because that one is very much a favorite in my house, so after 2 years and 2 purchases, I have barely any left of the remaining hemp chew, but still 2 of the dogwood chews that neither dog is as interested in anymore. I'd love to buy a couple more of just the hemp one.

      Your dog will thank you.
      Color: Dogwood & Fresh Breath, Size: Large
      My dogs loves to chew on these. They make a small mess but not as bad as other chews. They are food for keeping teeth clean.

      Nice chew toy
      Color: Dogwood Mushroom, Size: Medium, Color: Dogwood Mushroom, Size: Medium
      Super durable and puppy loves it. It was a bit hard for her at first but now at 5 months it’s one of her favorite things to gnaw on! It is heavy for the size but seems to be great quality and has given many hours of chew time with minimal wear.
