RideControl A. Introduction The purpose of this publication is to assist with the installation and maintenance of the RideControl air spring kit for the Toyota Tundra. The air springs used in RideControl kits are designed and manufactured like a tire. The air springs have layers of rubber and cords that control the bag’s growth and funnel it in one direction. The bags do not require a coil spring for control.

RideControl a. Remove any load and ensure it is on a level surface (fig. B.1). fig. B.1 b. If necessary (in cases where your leaf springs are sagging badly), use a jack to raise the rear end so that the vehicle achieves the original “as-delivered” ride height. 2. Measure the distance between the center of the hub and the bottom edge of the wheel well (fig. B.2). This is the Normal Ride Height. Enter the measurement below: NORMAL RIDE HEIGHT: __________ inches fig. B.
RideControl fig. B.3 fig. B.4 fig. B.5 fig. B.6 5. See figure B.6 for finished sleeve assembly. 6. Repeat assembly for other sleeve. INSTALLING THE SLEEVE ASSEMBLY 1. Remove the wheels. This kit should be mounted at normal ride height recorded on page 2. 2. Set the assembly on the leaf spring, forward of the axle. The tab on the lower bracket should hook over the forward leaf spring U-Bolt (fig. B.7). 3. Attach the lower bracket to the leaf spring using U-Bolt (D) and clamp bar (E).
RideControl 5. Align the upper bracket so that it is parallel and perpendicular with the lower bracket (fig. B.9). fig. B.9 6. Using the upper bracket as a template, mark one of the holes on the upper bracket (fig. B.10). fig. B.10 CAUTION BEFORE DRILLING, CHECK THE BACK SIDE OF THE FRAME TO SEE IF THE BRAKE LINES, GAS LINES, OR ANY OTHER LINES OR WIRES NEED TO BE MOVED BEFORE DRILLING THE UPPER BRACKET HOLES. 7. Flip the air spring down away from the frame.
RideControl 9. Attach the upper bracket to the frame with the frame bolt (F), oversized flat washer (I), fig. B.12 NOTE Cover the air fitting with a piece of tape to prevent metal shavings from getting into the fitting or sleeve. 10. Check alignment, adjust if needed, then center punch and drill the two lower holes in the upper bracket. 11. Torque upper bracket mounting bolts to 20 lb.-ft. (27Nm) (fig. B.13). fig. B.13 12. Continue the installation by following the air line installation instructions.
RideControl C. Installing the Air Lines This section explains how to set up the air spring kit to be controlled with Schrader valves and a separate compressed air source. An on-board air compressor system allows for hassle-free control of the air springs. Learn more about Air Lift control systems at www.airliftcompany.com/products/compressor-systems. 1. Choose a convenient location for mounting the inflation valves. Popuar locations for the inflation valve are: a. The wheel well flanges b.
RideControl 6. Route the air line along the frame to the fitting on the air spring (fig. C.1). Keep AT LEAST 6” of clearance between the air line and the exhaust system. Avoid sharp bends and edges. Use plastic tie straps to secure the air line to fixed points along the chassis. Be sure that the tie straps are tight, but do not pinch the air line. Leave at least 2” of slack to allow for any movement that might pull on the air line. 7. Cut off the air line, leaving approximately 12” of extra air line.
RideControl D. Before Operating CHECKING FOR LEAKS 1. Inflate the air spring to 30 PSI. 2. Spray all connections and the inflation valves with a solution of 1/5 liquid dish soap and 4/5 water. Spot leaks easily by looking for bubbles in the soapy water. 3. After the test, deflate the springs to the minimum pressure required to restore the system to normal ride height. Do not deflate to lower than 5 PSI. 4. Check the air pressure again after 24 hours. A 2-4 PSI loss after initial installation is normal.
RideControl INSTALLATION CHECKLIST Clearance test — Inflate the air springs to 75-90 PSI and make sure there is at least 1/2” clearance from anything that might rub against each sleeve. Be sure to check the tire, brakes, frame, shock absorbers and brake cables. Leak test before road test — Inflate the air springs to 75-90 PSI and check all connections for leaks. All leaks must be eliminated before the vehicle is road tested.
RideControl E. Use, Maintenance and Servicing Minimum Recommended Pressure Maximum Air Pressure 5 PSI 100 PSI MAINTENANCE GUIDELINES NOTE By following the steps below, vehicle owners will obtain the longest life and best results from their air springs. 1. Check air pressure weekly. 2. Always maintain normal ride height. Never inflate beyond 100 PSI. 3.
RideControl TUNING THE AIR PRESSURE Pressure determination comes down to three things — level vehicle, ride comfort and stability. 1. Level vehicle If the vehicle’s headlights are shining into the trees or the vehicle is leaning to one side, then it is not level (fig. E.1). Raise the air pressure to correct either of these problems and level the vehicle. 2. Ride comfort If the vehicle has a rough or harsh ride it may be due to either too much pressure or not enough (fig. E.2).
RideControl F. Frequently Asked Questions Q. The system won't maintain pressure overnight. What could be wrong? One of the air lines may be improperly installed or a line may have a hole or crack. Start by leak testing the air line connections. If no leaks are found, look for leaks in the rest of the air lines. Follow the steps in "Fixing Leaks." Q. One of the corners won't rise. Look for a kink or fold in the air line going to that air spring. Replace any line that has been kinked. Q.
