Now you can keep your stock arm just like it is and when you decide to go racing just bolt these on. Thats right! These bolt on to your stock arm and allow you to adjust your wheelbase lenght from 2" to 7" over stock for the hard launch you need to go fast at the dragstrip with out a big wheelie. When your done dragracing just remove these and your back to carving up the twisties. Made from T-6 6061 CNC aluminum billet block these are the strongest on the market. A extra feature that sets these apart form the others is these have the chain adjustments marks milled into them @ 1/4" adjustments...no more guessing...unlike the other copys cats on the market. The most note worthy feature that these have, that NONE of the others have is....the bolt in the picture... stays with the bolt on extension. The others on the market require that the bolt be shorter or longer when you move the axle. This means you have to remove and replace the bolt with different sizes. NOT THESE!!!! The bolt stays and allows the axle to move the complete lenght. Picture 1A shows how the is possible, the extra lenght of threads are hidden in the extension,inside the hole. Picture 2A shows the shape & taper of the block is kept to the factory look of the stock swing arm.
