Q & A

What's in the Box

Plastic carburetor spacers reduce the fuel temperature inside the carburetor by insulating the carb from the hot intake manifold. This results in a denser air/fuel mixutre for more power. Four-hole design increases low-end torque compared to open style spacers.

  • Fits 4150 and 4160 series Holley carbs
  • 1-3/4" venturi bores
  • 4 barrel carburetors
  • Gaskets NOT included

(Part #5921050)
                        

When you get beat out of corners on slick tracks, it may not be the skill of the other driver that's doing that to you!  Many of these teams are now relying on Track Control spacers from R2C for a smooth application of power.

For the days when getting a grip on a dicey track presents problems for even the best Late Model and Modified teams, R2C Track-Control carburetor spacers help solve the problem by applying smooth and consistent power to get you to the front. Take the edge off when driving out of corners and plant the power rather than blowing the tires off!

Holley 4150 4 barrel Track-Control spacers are designed to limit power production and control torque by reducing bore size from 1.75" to 1.25". In Dirt Modified testing, Track-Control spacers provide a power reduction of 50-60 HP with a corresponding reduction in torque on 675-700 HP engines. Track-Control carburetor spacers are 1" tall and designed to maintain perfect A/F quality and booster signal. The venturi shaped profile also helps control reversion while the phenolic construction provides outstanding strength and helps control carburetor temperatures.
