Selected User Reviews For ARP 251-2501 Bolt Kit
On a 1, this was actually used. Block of 8t 058 It fits perfectly after a few minor adjustments to the head. If the change was worthwhile, only time will tell.
It's a breeze to put together, and the bolts are a lot easier to torque than the OEM Mazdaspeed bolts.
This bolt was a perfect fit for my Mazda MZR 2. The engine is a 3L DISI.
Arp is the best, PERIOD. Excellent product at a reasonable price.
This bolt is a true work of art, and the attention to detail is evident when you hold it. FOR THUNDERBIRD SUPER COUPES HARMONIC BALANCERS, THIS IS THE APPROPRIATE SIZE BOLT.
The washer that came with it was too wide for what I needed (it wasn't designed for that purpose), but it worked out perfectly.
lbs). It was used on a 2. Duratec/MZR, 5 liters Excellent quality, smoothly torqued to specification (140 ft-lbs). lbs).
