I am adapting an nv3500 style trans behind my 5.3, and have already bought the 4.8 manual trans flywheel that uses the 12" truck style clutch. the trans input shaft is the 1-1/8" 10 spline. I am having trouble finding a good, reasonably priced clutch for this application though. the 5.3 will be seeing boost so I need something that will hold around 550-600 whp. anyone have any suggestions?

 

Based on the parts you mention above you can reference the link below (specifically the box for the 4.8L at the bottom of the page) for info. We offer 7 different options for this applications. Let me know if you have any further questions. Thanks!

awesome, thanks for that. how can I find what the torque capacity is on them? or what would you reccomend for a 3000 lb street/strip vehicle with around 600 whp? not sure how the stages are rated

 

Capacities would be similar to the LS1 based kits. My apologies for these not being listed on the link I provided. What is your planned torque output? Let me know and I will make a suitable recomendation. Thanks,
