T1R-S05 Mod-Twin 225 HD Sprung Race Kit performs aggressive launches and smoother shifting in high powered AWD’s by combining twice the ceramic friction surfaces with an ultra-durable Mono-Drive sprung hub assembly in a completely modular design. Each diaphragm spring endures an exclusive four-stage heat treating process providing a consistent light pedal feel. Puck-style Friction Plates with high quality ceramic friction materials deliver high friction coefficient, superior heat capacity, and long clutch life. These Friction Plates uniformly transfer torque to a Mono-Drive sprung hub assembly which extends input shaft life and reduces driveline shock from torsional vibration. This kit includes a CNC-machined and dynamically balanced flywheel, pressure plate cover, diaphragm spring, face, puck-style ceramic friction plates, sprung Mono-Drive hub assembly, floater, patented Monoloc Collar, release bearing, alignment tool and pilot bearing (if needed). Mod-Twin clutches are fully rebuildable and most components can be ordered separately.This Part Fits:

Amazon eGift Card Makes a Great Gift and So Easy to Give
Denomination: 0, Design Name: You're the best. (Animated)
I was so thankful that I could get this gift card on the Amazon website because I just had back surgery and I couldn't get out to the store to get my daughter something for helping me for a week. I just really wanted to show her my appreciation for everything she had done. I didn't know that you could do this and then I Googled it and it said I could. It was so effortlessly and so easy to do. I definitely will be doing this in the future now that I know how well it went.
