• Only the original "Bear Stop" is self compensating for wear, regardless of age.
• One piece aluminum casting prevents vacuum leaks, misalignment, distortion or loose parts commonly found in welded or bolted together throttle stops.
• Stainless steel butterflies are bolted to a ground stainless steel shaft.
• Actuating levers are TIG welded to the throttle shaft, preventing any possibility of loosening.
• We install a hard chromed plunger, brass solenoid bushings and nylon wear washers, and billet steel actuating mechanism.
• All electrical components are self contained inside the sealed, one piece solenoid.
• Indexed stop bolt makes setting easy, precise and simple to repeat.
• Opens and closes instantaneously, yet draws only 1 amp at wide open throttle.
• Packages complete with studs and detailed directions.
• Every part is either stainless steel or plated for corrosion resistance and professional appearance

The Bear Stop can be activated using a pushbutton shifter or
electric timer.

Use the provided pushbutton shifter switch that attaches behind the shift lever that is "on" (full throttle) in low gear, and "off" (closed throttle) in high gear.

Using an electronic timer (throttle stop controller) the controller replaces the shifter switch and the timer turns the throttle stop off and on as the car goes down the track.

In either method the throttle stop can be overidden allowing you to "run a guy down" on the top end by manually pushing an override switch.

 

The Bear Stop's electric solenoid opens and closes instantaneously, and draws only 1 amp at wide open throttle.

Nothing attaches to your throttle linkage, so the Bear Stop eliminates the dangerous possibilities of a stuck throttle. Dedenbear even installs plugs at the open shaft ends to prevent vacuum leaks.

As veteran racers, Dedenbear engineers understand that Holley carburetors like to run wide open.

The latest trend is to build mega-horsepower engines with Dominator carburetors to give high MPH top end charges. For maximum horsepower and consistency, Dedenbear has developed the "Big Bore" TS5 throttle stop.

MODEL TS5 - Fits Dominator Holley, King Demon

• Massive 2-1/8" throttle bores, 1:1 primary/secondary linkage, and an optional CO2 actuator that controls the butterfly opening and closing rates, this is the most advanced throttle stop ever made.
• The new CO2 actuator (p/n TS2/5R) is designed to prevent breaking the tires loose when the stop turns on and off and can even be used to retrofit existing TS2 throttle stops (Dominator stop with 2" bores).
• Optional primary butterfly kits allow shutting down all four holes.
• Each Bear Stop is packaged complete with studs, circuit breaker and detailed directions

All Dedenbear linkage style throttle stops come with a needle valve adjuster to control the opening rate of the throttle stop, quick disconnect fittings, stainless steel solenoid & cylinder, high temperature seals, and have all steel parts plated for corrosion resistance.

• TS-10 STANDARD LINKAGE STOP Economical general purpose in-line linkage stop for carbs or injectors. 3/4” bore, 2” stroke cylinder works well with single carbs and throttle body injectors. Includes Chrome moly adjustment bolts for maximum durability.
  
  
• TS-20 LONG STROKE BIG BORE LINKAGE STOP
  All the same features as the popular TS10 plus a larger 7/8” bore, 2 1/2” stroke cylinder. The bigger bore and longer stroke make this stop ideal for starting line control, dual carbs or bird catcher injectors.
  
  
• TS-15 EASY ADJUST LINKAGE STOP Just like the TS10 but inverted mounting allows easier access to the adjustment bolt. Great for racers who make frequent changes to their throttle stop position. 3/4” bore, 2” stroke cylinder.
  
  
• TS-25 LONG STROKE BIG BORE EASY ADJUST LINKAGE STOP
  Just like the TS20 but inverted mounting allows easier access to the adjustment bolt. Great for racers who make frequent changes to their throttle stop position. 7/8” bore, 2 1/2” stroke cylinder.
  
  
• TS-30 DOUBLE ACTING KNOB ADJUST LINKAGE STOP
  Air on / air off cylinder design makes this linkage stop super smooth. 7/8 bore, 2 1/4” stroke will operate any induction system and works great on high horsepower applications. Incredibly simple knob adjustment. Includes premium remote solenoid package.
  
  

Throttle stop kits including an AB10K Bottle Kit:

• MODEL TS10K
• MODEL TS15K Easy Adjust
• MODEL TS20K CO2, Long Stroke, Big Bore
• MODEL TS25K Long Stroke, Big Bore, Easy Adjust
• MODEL TS30K Double Acting, Knob Adjust

Since the Bear Stop uses its own set of secondary butterflies to regulate air/fuel flow, your carburetor operates at full throttle throughout the run. Fuel metering always remains correct, and weather changes can be compensated for predictably. (An optional Primary Butterfly Kit is available with a second set of butterflies and linkage.)

Adjusting the Bear Stop is simple.
An indexed stop bolt lets you easily make precise and repeatable settings. Using a throttle stop controller to activate the stop results in even more accurate E.T. adjustments.
