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
Not exactly happy, as it did not get my product on time and not happy with services
It help me to keep my vehicle level while preventing it from sagging and swaying.help me with durability and quality performance for my Toyota truck, great help, seems to do very well and thanks for all the help.
The springs did not fit my 2002 Toyota Tundra as advertised. I called SD and the rep said we'll have you talk with the manufacturer. The Hellwig rep later advised they did not have any alternatives. I sent an email to the SD Springs rep I had been dealing with advising I would like to return the springs since they didn't fit. To date, I've never heard back from anyone. I'm very disappointed with this customer service experience. I my order # was 105238 and I have no intention of buying anything from SD again...
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!
