Valvetrain precision drives victory—enter this push rod (SKU: 555531, superseded by 693517) for Briggs Animal setups.

• Hardened steel construction for flex-free operation.
• Exact length maintains optimal timing.
• Reduces valve float at peak RPMs.

As the link between cam and rocker, it translates lobe action into power pulses, enhancing combustion efficiency for faster straights. Track engineers use it to fine-tune, organizing parts for repeatable performance. Without it, timing slips lead to sluggish revs; with it, your kart surges ahead.

Compatible across Animal variants, this rod helps you dominate by keeping the top end synchronized and reliable.

Frequently Asked Questions

Q: Why was the original 555531 push rod superseded by 693517?

A: Briggs & Stratton periodically updates part numbers to reflect manufacturing improvements or inventory consolidation. The 693517 is the current, direct replacement for the 555531 and maintains the exact specifications required for your Animal or LO206 valvetrain.

Q: How do I know if my push rod needs to be replaced?

A: You should inspect your push rod for any signs of bending, pitting, or wear at the contact points. If you notice sluggish revs, inconsistent valve timing, or increased valve float at high RPMs, the push rod may be compromised and should be replaced to restore engine performance.

Q: Does this push rod require any special break-in or setup?

A: While no specific break-in is required, it is critical to ensure your valve lash is properly adjusted after installation. Always verify that the rod is seated correctly in the lifter and rocker arm cup before tightening your rocker arm assembly.

Q: Can I use this push rod in both the Briggs Animal and LO206 engines?

A: Yes, this push rod is designed for compatibility across the Briggs Animal platform, which includes the LO206 and World Formula variants. It is an essential component for maintaining the precise valve timing required for these engines.
