T1R-S07 Mod-Twin 225 HD Rigid Race Kit tackles aggressive launches and rapid shifting of high powered AWD’s by combining twice the ceramic friction surfaces with a no-nonsense solid Mono-Drive hub 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 chrome-moly hub which is heat treated for strength and durability extending input shaft life with one continuous spline. The lightweight, rigid design allows for quicker shifts and trouble-free service. This kit includes a CNC-machined and dynamically balanced flywheel, pressure plate cover, diaphragm spring, face, puck-style ceramic friction plates, rigid Mono-Drive hub, 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.

He loves them.
Size: 4.5 Big Kid, Color: Black Orange
Great construction and very durable. I’ve got an 8 year old boy who loves to play rough. He wears them through mud, grass, gets them wet, anything you can imagine. They clean really easily, which is a lifesaver when you’ve got an 8 year old. He loves the colors and his friends think they’re cool, which is a bonus. They support his arches well, fit just right, and are true to size. These can be worn as daily walkers, gym shoes, running shoes, or when he wants to look fly. These grip is strong - great for gym class. Very affordable and well worth it. Shipped quickly. Multiple uses for sports, walking, basketball, soccer, whatever. The laces are tough and the tongue is well constructed, as is the heel and the sole. Works perfectly.

The BEST kids tennis shoes
Size: 11 Little Kid, Color: Black/Green
I just bought a second pair of these for my son. The first pair lasted a whole school year, which is pretty good for an active 4 year old, and he still loves them though they look a bit beat up. Got him a new pair for his birthday and he’s so excited. Worth every penny. True to size and they are apparently very comfortable.

I will keep buying these
Size: 3 Big Kid, Color: Black Orange, Size: 3 Big Kid, Color: Black Orange
This is the third time I have purchased these shoes. Every time my son grows out of them I buy the next size up. His favorite color is orange, so he loves the look of these. They are also soft mesh around the toes, which he loves so he can wiggle his toes. These are durable and well made. The pair i purchased before these is still wearable, just too small for him now. These are his daily shoes. The price has gone up since my first purchase, but they still are not unreasonable for how long they last. He is an active boy. He climbs trees, runs, and plays hard. So for any show to last 6 months when he wears them daily it shows the durability. It also shows that these shoes have tread on them thay stops him from slipping. He is able to move around freely and never has issues with grip. He puts them on without difficulty.
