What is the height of the poly locks in this set?
Verified Reply - Solomon
Hi Mark, I'm glad to help you! This Proform Rocker Poly-Locks (Part # 66935) has a height of 1"- inches.
Will this proform roller rocker fit the roller arm on a 350 Chevy engine?
Verified Reply - Solomon
Hi Teneka, I'm glad to help you! We can only look up by the vehicle. Since you didn't mention the specific vehicle, it's hard to tell for sure. To give you the correct information I would need the year, make, model and engine size of the vehicle.
Are they for standard rocker arms or will they work with roller rocker arms?
Verified Reply - Steve
Hi Freddie, I'm glad to assist you! This Proform Rocker Poly-Lock - Part # 66935 is for roller rocker arms. This is designed to fit most extruded aluminum rocker arms.
Is this a set of 16
Verified Reply - Solomo
Yes, Ken! This Proform Rocker Poly-Lock - Part # 66935 is sold as a set of 16.
