2015-2022 Subaru WRX/STI Master Cylinder by Clutch Masters x WilwoodWhen upgrading your clutch, don't overlook upgrading your clutch master cylinder as well. Typically the OEM master cylinder will work just fine, but sometimes that master cylinder is getting old and tired and possibly might be leaking. Or maybe you want just a little bit of a crisper pedal feel when operating your clutch. Upgrading to the Clutch Masters X Wilwood Clutch Master Cylinder will make sure your clutch hydraulic system is up to snuff and able to handle more aggressive driving. The other notable upgrade this kit will do for you eliminates the clutch delay valve that is built into the factory master cylinder. The delay valve is a one-way regulating valve that slows the fluid returning from the slave cylinder after you let off the clutch. This delay is especially noticeable in quick 1-2 gear shifts where you get back on the gas before the clutch is fully engaged. By getting rid of the delay valve you can shift quickly and the clutch is immediately engaging. On high-powered cars where you want to still enable a little bit of delay or slip of the clutch to prevent the drivetrain from getting a shock, check out our tuneable Flow Control Valve.
This is a complete plug-and-play kit and includes everything you need to install this system. Will work with OEM slave cylinders.
Kit includes Wilwood Master Cylinder, (.750" Bore) 3an stainless steel line, fittings, hardware, billet aluminum master cylinder adapter, billet aluminum reservoir cap, and billet clevis.

Perfect All-in-One Pet Enrichment Set!
Color: All-Around Dog Puzzle Toys
This puzzle dog toy set is amazing! It’s the most thoughtful and efficient enrichment set I’ve ever used for my crew.
The lick mats are high-quality, durable, and the included cleaning brush makes cleanup effortless by reaching every groove. The spatula is perfectly designed to spread treats like peanut butter or yogurt evenly, saving time and preventing messes. These small details really set this set apart from others.
Beyond the lick mats, the set includes a puzzle feeder and three puzzle balls that keep my furry babies mentally stimulated and entertained. Each toy is durable, easy to use, and provides a great challenge for everyone. The variety in this set ensures there’s always something to engage my critters and meet their varying challenge level needs.
It’s clear this set was designed with both dogs and owners in mind, addressing common pain points like cleaning and mess-free prep. It’s perfect for smart dogs (and other critters!) and delivers great value for the price.
If you’re looking for interactive, mentally stimulating toys for your pet, this all-around set is a must-have. My crew love it, and so do I. Five stars!

Great set!
Color: All-Around Dog Puzzle Toys
This is a great set to entertain and beat your dog or puppies boredom! The material is natural so safe there! It’s also very durable ! The mats have suctions on bottom which is very smart ! The treat balls make a good toy even without treats in my experience. You also get a couple free gifts which was a nice surprise.

Great set of dog toys. Lots of variety!
Color: All-Around Dog Puzzle Toys
Great variety of different dog toys. Keeps my dog entertained for a while! She loves the round one with sliding doors. The rubber balls are well made and provide a longer time of play.

Great package of toys
Color: Curated Dog Puzzle Toys
We have a new rescue dog and she eats too fast so we got these to help slow her meals down, and to give her something to do during downtime. The balls are so fun for her, the puzzle one is cool but she knows how to get the food out now so it doesn't take her long to finish it. The lick pads are nice but I have to place them on a cookie sheet so it doesn't get our hardwood floors oily with peanut butter. I think thos whole bundle is a great value. Side note: do not leave your dog alone with these toys because they will chew them up easily. I take them away once the treats and food are gone.

Not made to last..
Color: All-Around Dog Puzzle Toys
I got this kit to help entertain our litter of Golden Retrievers as they got bigger, waiting to go to their forever homes. The quality was pretty good. It worked great when they were small, but as they got bigger and stronger, they were able to chew up and destroy the balls, especially the hollow ones. The balls that hold the treats in between the layers help up better, but after 3-4 months I took them away because they started showing teeth marks. The lick pads have lasted, we still have them 6 months later, and the puzzle thing was ok until about a month ago when the puppy we kept learned to pop the sliders off instead of push them to the side. All in all, I’d say it is ok to entertain very small puppies or dogs that don’t chew a lot, but definitely under supervision. Definitely not for aggressive chewers or larger dogs, as the balls are all very small.
