Speedfactory 4140 Head Stud Kit for Honda B/K-Series

If you're looking for a way to boost the performance of your Honda/Acura B & K series engine, consider the SpeedFactory Racing 4140 Head Stud Kit. This kit is designed for forced induction applications requiring up to 800+HP. One of the critical features of this kit is the large forged nuts and washers, which help to distribute the load more evenly across the surface of the engine block. This can help to prevent damage and improve overall performance.

Another benefit of the SpeedFactory Racing 4140 Head Stud Kit is the hex broach on the top of the stud. This makes installation much easier, as you can use a wrench or socket to tighten the stud. The kit also has a dog point end, which helps seat the stud in the block and preload the fastener for more consistent and accurate torquing. All of these features work together to create a more reliable and high-performing engine that can handle the demands of forced induction.

Features:

• 210,000 psi tensile rating
• Hex broach on the top of the stud for ease of installation
• Dog point design for superior preload
• Oversized forged 9/16” 12-point nuts and hardened parallel-ground washers for superior load distribution compared to the smaller 1/2” nuts and washers most used.
