March, 2019 (Cookeville, TN) The truck that started the Sport Truck movement is back again and hotter than ever! American Powertrain now fills in the gap of high performance manual transmission options for the C1500 series with their new 1988-98 Chevy/GMC (OBS) truck 5 and 6-speed Kits.
As with all American Powertrain kits, these systems feature the TREMEC TKO 5-speed and Magnum 6-speed coupled with all the parts needed to successfully install these transmissions with an excellent shift position for both bench and bucket seat projects. No modifications are required to the tunnel for 5 or 6-speed.
Both kits allow use of the stock cross member with only a few holes to drill in the frame making the install a breeze. Using the stock cross member and moving it down the frame also helps with LS engine swaps as well. To make it even easier, this kit can use the stock clutch master kit and pedal with adapter line to use our Hydramax Hydraulic clutch sleeve. A Wilwood bolt in master cylinder upgrade is also available. The kit also includes electronic speedometer solution, VSS set-up for EFI, pilot bearing, Weatherseal reverse light wiring, complete seamless DOM driveshaft, shift knob, hardware and instructions. If you are starting with an automatic or an empty chassis American Powertrain can provide all the parts you need for a diff to block installation.
A Pro-Touring series upgrade is available on all kits with a balanced aluminum driveshaft and their billet White Lightning shifter for maximum performance. All transmissions are available with their Xtreme upgrade to handle up to 1100ft-lbs. of torque and high rpm shifting.
All ProFit kits are covered by AP’s 2-year warranty and their exclusive Extended Hours customer first tech support. Complete kits start at around $3495 and are available now. Call us at 931-646-4836.
