B&M Performance and Off-Road introduces the new Rock/Race GM TH400 Automatic transmission specifically designed and built for Off-Road competition. The foundation starts with a tough and tested Reid Racing Super Hydra 400 Off-road race case and SFI 30.1 certification bellhousing that fits all Chevrolet 90 degree V8's including early and late LS engines and 4.3L V6 engines. Upgrades include a new super tough 300M (Rockwell Hardness) alloy steel 30 spline input shaft, a new Direct Drum with 34 element sprag and a wide Intermediate band for increased engine braking capability, strength and performance. Other features include a Billet 1045 alloy steel forward hub with bearing, four friction Intermediate clutch pack and a Reid Racing tailhousing with roller bearing providing superior support for the 32 spline output shaft. The forward pattern manual valve body has been recalibrated to ensure constant pressure, quick shift response and provides engine braking. The transmission is finished off with a B&M Hi-Tek finned aluminum trans pan which both increases fluid capacity and quickly dissapates heat generated by tough off-road race conditions. Handles up to 900 HP/900 LB/FT

As performance enthusiasts today, most people are accustomed to having access to whatever performance parts they need for their vehicle readily available at their local dealer. It usually never crosses anyone's mind who invented these products? Who was the first to identify the need, then develop and manufacture that product? Since the very early 1950s, B&M has been at the vanguard of the growing automotive aftermarket. Racers themselves, B&M's founders identified the needs of local racers and street performance enthusiasts, and developed products to fill those needs. As the industry grew so did B&M. And as racers went faster, B&M developed products to help them break the records they just set. In the 50's it was B&M who came up with the idea of using a performance reinforced Hydramatic for racing. In the 60s it was B&M who developed shifters to go along with it, and later in the decade came race converters. In the 70's shift and transmission improving kits, and always the constant refinements and expansion of existing product lines. If you've ever raced a vehicle, or driven a hot rod with an automatic transmission, high stall torque converter, an aftermarket automatic shifter, or performance enhancing shifting kit, thank B&M. From Trick Shift performance ATF to reverse pattern valve bodies, 1.80 gearsets to cool canisters, the list of firsts goes on and on. It's this tradition that keeps moving B&M to identify and develop what the performance enthusiast needs. As racing and street performance has spread globally, B&M has taken it's extensive knowledge and experience and applied it to the needs of racers, everyday drivers and hobbyists around the world. Keep looking to B&M to continue to be amongst the very first to identify vehicle needs in the global automotive aftermarket, supplying enthusiasts and racers what they need, performance!
