Racetech RT4100HR Standard Size Racing SeatThe RT4100HR is a standard sized fiberglass race seat equipped with head restraint wings for enhanced safety. We have focused on achieving a lightweight seat shell with optimized geometry.

Large harness guides and a removable molded base cushion allow a range of drivers of varying heights

The RT4100HR is a standard-sized fiberglass race seat equipped with head restraint wings for enhanced safety. We have focused on achieving a lightweight seat shell with optimized geometry. Our back-mounted technology has trickled down from the 119 and 129 Series, giving you the option of bolting the back of the seat to the roll cage at shoulder level. Large harness guides and a removable molded base cushion allow a range of drivers of varying heights to fit. Breathable Spacer fabric, parallel sides, and pronounced thigh support round off the features of this accomplished motorsport seat. For the larger driver, the RT4100WTHR is 60mm taller and 40mm wider and for those wanting a seat without head restraints, our RT4100 and RT4100WT complete the 4100 Series. The 4100 Series seats use Racetech RTB1009M aluminum side mount brackets or the optional RTB2009S steel side mount brackets.

Perfect for that Drag Race Outlaw, No Prep Car or Door Slammer when you need to be safe and comfortable.

Heavy duty brackets!
Size: 8 Inch, Color: Gold, Size: 8 Inch, Color: Gold
These brackets are heavy duty and came with the correct hardware. They were easy to install, the two holes were so helpful to know where to mark them. I think because they’re heavy duty you can place a good amount of weight on your shelves. The only thing I wasn’t happy with is that 4/69 of shelves, the paint was chipping but it was the perfect gold color.

Don't hesitate - Great product!
Size: 12 Inch, Color: Black
Superior quality at an unbelievable savings over local retailers. Hardware for hanging included the cheaper plastic lags yet they also included the heavy duty lags, so no tapping in to our supply. Thank you for a great product
