Q: Is there any drilling required?
A: No there is no drilling required to install the 991 helper springs onto your Toyota. The U-Bolts required to install these specific helper springs bolt right into the leaf that is nearest to the axle
Product has been satisfactory and would recommend you to others. Thanks.
I got these helpers with rear sway bar. Installation was simple. Night and day difference. Truck handles a million times better even when not towing! Recommend to anyone with a half ton truck! Ordering was easy and operator was very informative. Thanks SD! I love both items!
