DP Racing Universal Rear Bumper Bolt Assembly Kit - DP-391 - Oval & Dirt Track

When sourcing components from a premium kart store, securing your rear bumper with the DP-391 bolt assembly is critical for maintaining structural integrity during high-impact oval and dirt track racing. This complete hardware kit delivers race-proven shock absorption, preventing the loosening that compromises rear-end protection. Engineered to reduce frame stress, the included grommets and plastic inserts cushion the chassis against aggressive rear contacts. Whether you are dialing in your setup with new go kart axle kits or fine-tuning your chassis balance, a rigid and reliable bumper mount ensures your focus remains on performance rather than trackside repairs.

Precision Mounting for High-Vibration Racing

Every component in the DP-391 assembly—from the high-tensile bolt to the vibration-damping grommets—is selected to withstand the extreme harmonics of competitive karting. Just as you would meticulously bleed a kart brake kit or calibrate carb parts for optimal engine output, securing your rear loop bumper demands exact tolerances. This kit provides a comprehensive solution, sold individually per side, allowing racers to replace damaged hardware quickly and keep their karts race-ready.

Seamless Integration with Your Go Kart Steering Wheel Upgrade

Chassis feedback is everything. A loose rear bumper translates to unpredictable vibrations that can mask the precise tactile feedback you expect after installing a go kart steering wheel upgrade. By locking down the rear loop bumper, this bolt assembly ensures that the energy transferred through the frame is pure, giving you the confidence to push the limits on dirt or asphalt ovals. It is an indispensable addition to your pit box, streamlining installation and maximizing your time on the track.

Frequently Asked Questions

Q: Does this kit include everything needed to mount one side of my rear bumper?

A: Yes, the DP-391 is a complete assembly. Each kit includes the high-tensile bolt, nuts, washers, vibration-damping grommets, and the plastic insert required to secure one side of your rear loop bumper.

Q: How many kits do I need to purchase for a full rear bumper installation?

A: Since these are sold individually, you will need to purchase two kits to secure both the left and right sides of your rear bumper.

Q: Why are the grommets and plastic inserts important for my kart's chassis?

A: These components provide essential vibration damping and prevent metal-on-metal contact. By cushioning the bumper against the frame, they reduce stress on your chassis rails and prevent premature wear caused by the high-frequency vibrations common in dirt and oval track racing.

Q: Is this hardware compatible with all go kart rear bumpers?

A: This kit features universal fitment designed for standard rear loop bumpers commonly used in oval and dirt track racing. It is engineered to provide a secure, high-tolerance fit for most competitive racing chassis.

Q: Should I use thread locker on these bolts?

A: While the assembly is designed for a secure fit, many racers choose to use a light-strength thread locker as a precaution against the extreme vibrations encountered during high-impact racing sessions.
