The B&M SuperCoolers combine improved protection against lube system failure while keeping the required levels of optimal heat transfer.
Do you want to add fluid capacity to your transmission? Check out LMPerformance's offering of B&M Deep Pans. Being able to hold extra fluid means more cooling. More cooling means better efficiency and performance. Increase your transmission's life with a B&M Deep Pan from LMPerformance. B&M parts at the best price.
If you follow the history of B & M you will soon see why their reputation in the automotive aftermarket industry is secure and impressive. B & M’s founders have a background in racing and as such knew where to start when it came to identifying areas that needed improvement. They are responsible for impressive new ideas in the performance world, ideas like HYDRAMATIC for racing applications and shifters to go along with that, then race converters, shift and transmission improving kits and the list goes on. If you follow the racing circuit then we are sure you are familiar with B & M and its contributions to not only the racing industry but to the performance car industry as well.
