Customer photo review of Tirecockz Prank Dick Shaped Valve Stem Caps

I secretly put these in my husband’s truck. He has not noticed yet. To be continued! Well crap! He totaled his truck last night. Never saw my addition!

Customer photo review of Tirecockz Prank Dick Shaped Valve Stem Caps

I bought these to put on my buddies truck thinking it would take a month or so till he noticed. Boy was i wrong. The day I put them on his truck is the same day he randomly wanted to trade his truck in. He didn't notice them till after they had looked at his truck and given him a price. 10/10 the best thing to happen. Now they have moved on to the next soul. And I have a feeling random people's stems are going to be rock hard as they make their way around. If your think about buy this do. The quality is amazing. Just know they are a little bigger then you think.

Customer photo review of Tirecockz Prank Dick Shaped Valve Stem Caps

NOT FOR MOTOR CYCLES. (Or at least Harley, FATBOB) Let me explain.. they are made with quality & hilarious. However, the length and weight of the cox on a spinning wheel literally bend the valves to their braking point. The cox plus the centrifugal force from the wheel sliced the valves. Causing the air to escape. One actually flew off. I had to push the bike off the highway, a tow truck pick me up & have the valves replaced. A very sucky, very very Expensive experience. I would stay away for Harley use. I cant speak on other bikes or cars.

Not sure if this company is up and running. I placed an order on 15 Feb and I’ve still haven’t received it. I’ve emailed and reached out on instant messaging with no response. They will take your money but not send out their product. Please be aware!!!
