### ⭐⭐⭐⭐⭐ Review
*by T***H on 11 August 2025*

High quality and seem super strong. I did not feel like I had to worry about breaking a bolt while torquing them with odd ratchet and wrench setups due to difficulty in reaching them. I did do a re-torque after a few heat cycles and a few of the bolts did need to be snugged back down. Unsure if that was a result of not enough torque during initial install or if they backed out, but no issues since then. Overall happy with these.
