Product Details

The ARP 134-7401 thermostat housing bolt kit provides a reliable solution for preventing coolant leaks at your thermostat housing connection. These premium-grade fasteners are precision-engineered to properly engage manifold threads and resist loosening under thermal cycling and vibration.

Key Features:

  • Application-specific design ensures proper thread engagement and sealing
  • 12-point head design allows easier access in tight engine compartments
  • Manufactured from high-strength chrome moly steel with black oxide finish
  • Superior clamping force compared to OEM fasteners prevents loosening
  • Includes washers for complete installation

Extremely fast shipping and delivery! I received my item within 24 hours of ordering.

Grŕrrrrrrrrrrrrrrrtttteeeeeeeeeeeeeereeraaaaaaaaattttttttttttt

Great site to order from

Site use was easy, and product shipped promptly after ordering. Price was the best I could find, would use this business again.

Your check out process through amazon showed error. I have NEVER had a problem checking out with amazon!!!

Lowest price on EBC brakes for my Subaru. Good speed on processing.

First I found Autoplicity through The Find, they already had the item discounted, other than all the other online stores where you needed to search for coupon codes. Then the transaction was very simple, they accepted PayPal which was the payment method I wanted to use.<br>I'm very happy with my purchase and the service I got from Autoplicity.

Ordered a CAI kit and Autoplicity had the lowest price. They're website didn't correctly match my vehicle to the product and it took a few days to ship. They're support was friendly and quick when I emailed them about the delay.
