Installation Instructions 1. After removing the factory lower control arm, clean the bushing mounting surfaces on the frame and lubricate with lithium grease. 2. Fasten the lower arm to the frame with the ½” x 3 ½” bolts and Nylok nuts supplied. Note: On some cars the frame brackets may be pinched and will need to be spread back apart to allow bushing to slide in. 3.
. Screw a 3/8” x 1 ¼” bolt and nut into the hole in the side of the lower arm. This will act as an adjustable steering stop. After the wheel is install check wheel clearance all full lock and adjust as necessary. 8. If using factory style sway bar, shorten the sway bar end link spacer to 1 ½” tall. New 3/8” x 5 ½” bolts and Nylok nuts are supplied.

Installation Instructions 1. On some cars, to remove the upper control arm you must remove the bolts, which are pressed into the frame. We made this slide hammer adapter (a nut with a piece of angle iron welded to it) to aid in removing the bolts. Driver Side Top View 2. Fasten the upper arm to the frame using the factory hardware. Reinstall the current alignment shims, but vehicle must be realigned. This arm was designed with an extra 2 degrees of positive caster with the centered caster slugs.
These Strong Arms come equipped with a changeable caster slug setup. This allows you to add or remove caster from the front suspension, if desired. The caster slugs that come in the kit are setup to put the control arm in the centered position, which is approximately 3 degrees of caster. The caster slugs allow you to add or remove caster without having to use a stack of shims. If more or less caster is desired, optional caster slugs can be purchased from your Ridetech dealer or Ridetech.

INSTRUCTIONS FOR Ridetech Tall SPINDLES These spindles will fit ’67-69 Camaro, ’64-’72 Chevelle, and ’68-’74 Nova. They will provide a 2” drop, and are taller than stock to improve the car’s cornering ability. The raised upper ball joint will cause the tires to lean into the corner, like a motorcycle, rather than outboard as the shorter stock spindles do. This camber action change also raises the roll center for less body roll, and transfer the car’s center of gravity inboard in the turn as well.
Disassembly of the ball joints from the spindles can be eased by making the simple tool shown in the photo below. A pair of 1 ½” long bolts are threaded into a matching hex coupler. The ball joint cotter pins are removed, and the hex nuts loosened a couple turns. Place the tool between the ball joint studs, and turn a bolt to expand the tool, gently popping the ball joint studs loose.
If you remove the calipers but leave the hoses attached, supporting them to avoid stressing the hoses, you won’t even need to rebleed the brakes! Reattach the new spindle, being sure to get the castle nuts tight, and install new cotter pins. Attach the steering arms into the lower holes in the spindles using the 4 supplied 1/2NFx2 1/2” long flathead bolts and Nyloc nuts supplied. The 1/2NFx 2” long flat head bolts and nyloc nuts we supply are for use with Wilwood and Baer brake kit lower bracket bolts.

1. Raise the vehicle to a safe and comfortable working height. Use jack stands to support the vehicle with the suspension hanging freely. 2. Support the axle and remove the bump stops, leaf springs, shocks and tail pipes. Refer to the factory service manual for proper disassemble procedures. Keep the factory upper shock bolts, bump stop bolts, U-bolts, and front leaf spring mount and bolts. 3. One more thing needs to be removed before starting the assembly; it’s the pinion snubber and mount.
9. The lower axle bracket will be fastened to the leaf spring pad using the factory U-bolts. It is offset to the inside of the car. New 7/16” nylocs are supplied. 10. Bolt the lower Shockwave mount to the lower holes of the axle bracket if you have a monoleaf car. If you have a multileaf car the bottom of the billet mount will be flush with the axle bracket. 11. Swing the lower bar up to the axle bracket and insert 5/8” x 2 3/4" bolt. The standard hole is the center hole like in the picture.
15. How do you set the pinion angle? On a singlepiece shaft you want to set it up where a line drawn through the center of the engine crankshaft or output shaft of the transmission and a line drawn through the center of the pinion are parallel to each other but not the same line. A simple way to do this is to place a digital angle finder or dial level on the front face of the lower engine pulley or harmonic balancer.
16. One helpful trick to help maintain ride height and pinion angle while adjusting is to tack weld a spacer between the axle and the outside of the frame as shown in the picture. This spacer should be 8 3/8” tall giving the Shockwave an eye-to-eye measurement of 14 1/2" to 15”. 17. After double-checking pinion angle, ride height, and axle center the tabs can be tack welded. Remove the bar to avoid frying the bushing and finish welding the tabs to the axle. 18.
Upper Bar Installation Jig This jig has been supplied to aid in the installation of the upper 4 link bar. It can be temporarily used to properly align, locate and weld the tabs onto the axle. It will also ensure that the mounting bolts are parallel to the ground. Follow the diagram below to set the jig to the same length as the upper bar, use the 3/8” x 3/4” bolt and nuts to set the length. Position the axle at ride height. Center the axle left to right between the quarter panels.
