Mastodon Rocker Arm Studs 351-302 Windsor

Crafted from certified aircraft-quality, heat-treated aluminum, they're matched to massive, precision-ground trunnions for superior durability, and optimized rocker arm geometry evenly distributes the load for maximum strength.

Mastodon rocker arms also utilize oversized needle roller bearings for better load distribution and longer service life. Finally, they're black anodized; you'll want to leave your valve covers off!
