A Must Have Product
Michael Wartenbee (Currituck, NC) 8/10/2016 6:28 AM
Order # 488885 This is a must have product with the Exhaust Brake. Control is at your fingertips and its extremely solid. All metal bracket split down the center so you don't have to take the shift knob off to install it. I didn't even instal the factory toggle switch that came with my Exhaust Brake, just this great product. My 2003 Dodge will engage the Exhaust Brake shortly after pushing in the clutch so as I'm rowing through the gears after take off, the Exhaust Brake will begin to engage five times (6 speed transmission). Now I just switch it off while taking off and as I slide it in 6th gear, I engage the switch. Can't get any easier than that. Trust me when I say, you will want this product.
