JackRabbit The JackRabbit Hard tonneau cover retacts out of the way and into the canister at the front of the truck bed. JackRabbit is made of Weather-resistant padded polymer laminated to rigid aluminum panels that glide along black powder-coated side rails, a heavy-duty spring helps the tonneau cover retract smoothly and easily. The built-in pull strap engages the latch at 12" intervals on short and long-bed models. JackRabbit has an easy no-drill, clamp-in design (in most applications). JackRabbits low-profile, aerodynamic design saves gas up to 11%. The cover fits over 5th wheel trailer hitches and has a three year parts warranty.
