Product Details

The Percy's High Performance 21010 Exhaust Manifold Bolt and Spring Kit is designed to provide a reliable, leak-free seal for high-performance exhaust manifold installations. This kit combines specially engineered bolts with high-tension springs to maintain consistent clamping pressure on exhaust manifold flanges, even under extreme thermal cycling conditions.

Key Features:

  • High-strength bolts designed to withstand extreme exhaust temperatures
  • Heavy-duty springs maintain constant pressure to prevent gasket leaks
  • Compensates for thermal expansion and contraction during heat cycles
  • Prevents common exhaust manifold bolt failures and blown gaskets
  • Ideal for racing and high-performance street applications
  • Professional-grade hardware for reliable installation

Percy's High Performance exhaust hardware is engineered to address the unique challenges of high-temperature exhaust systems, where conventional bolts can loosen or fail due to repeated heating and cooling. The spring-loaded design ensures continuous pressure on the manifold gasket, reducing the risk of exhaust leaks that can affect performance and cause damage.

GREAT WEBSITE. LIGHTNING FAST

Quick easy and hassle free check out. Item looks great on the truck!

I paid for 2nd day shipping and 5 days later they were shipped out. So, I should receive my rotors in a full week from when I paid for 2 day shipping. I called customer service and they discounted the shipping rate to ground service. At least they were polite and helpful in the phone.

Autoplicity won my loyalty as a customer on two separate counts. Firstly, I am always researching the web for the lowest possible price on an item even while I am in the process of actually ordering it. I had filled in all of my info on their order page and had competed almost everything required concerning making this order. All that was left to do was my clicking of the final 'link' actually confirming the order. At this point I totally stopped and looked elsewhere on the web. A couple of hours later I came back to my computer and was surprised to see an email from Autoplicity asking me why I hadn't fully completed my order and offering me 3% off the purchase price if I would complete it. I immediately finished and submitted the order without hesitation. Secondly, a day or so after I had made the order, I received another email from Autoplicity offering me an additional $5.00 rebate if I wrote a review of my experience with them. Do you think they really want me as a customer? YOU BET!! I like companies that do business like this. They know how to make and keep loyal customers.

excellent...smooth transaction
