upon using a lift coil on the front of your truck, Assuming you have the factory arms/ect, the geometry will change and it wont be very fun to drive (turn corners).
Go with the lift spindles!!! A friend of mine was running a '98 Ford F150 2wd with a complete Fabtech kit. It was very very very fun out in the desert
I've never heard of Chassis Tech, but I
KNOW that Fabtech makes some quality parts. Is it worth the extra $200?! Maybe... maybe not...
