My factory seats are too high will this fix that?
These will not work with factory seats but it correct that if you also install aftermarket seats with the correct mounting pattern of 14 inch by 18 inch. These will NOT work with stock seats
Will these work with any aftermarket seat?
They are designed for seats with a 14 inch by 18 inch mounting pattern, which is common across many aftermarket brands including PRP.
Do these mounts retain the factory fold and tumble feature?
No. These brackets are designed for fixed aftermarket bucket seats and do not support fold and tumble functionality.
How much lower will I sit compared to factory mounts?
That depends on configuration, but running the brackets in the lowest position lowers the seating position typically around 1.5 inches with aftermarket seat installs.
Are these required for installing PRP seats in a Jeep YJ?
They are required when running their suspension style seats.
