Our Price: $74.95

Had a coil pop out under maximum flex? We did! So WE designed the heavy duty replacements to securely hold your coils in place.This allows full flex (of even the last wrap!) without fear of your coil popping loose! Our simple, but effective, one piece design replaces both of the OE pieces. It sits flat on top of the radius arm or our 4-Link truss, also reducing coil bowing. Combine with our axle wedges for axle conversions. Stitch welded and laser cut for drainage. Zinc plated for rust resistance. Fits EB & 78-79 (5 1/2 diameter) Coil springs. Our passenger side retainer has been offset for full coil engagement, we've marked on the retainer plate so you know exactly where they belong when installed. These will insure a long lasting product with optimal coil engagement compared at full droop to others on the market.

These will work for our t-rex arms, extended radius arms, or the stock radius arm.
