[crikeymike]

After many years of requests, Dobinsons have finally come out with bump stop extensions to run with the 4" and 6" length shocks they offer.

BS59-608 - Dobinsons 80 Series Front Bump Stop Extensions Kit (1.0-2.0 in)
BS59-609 - Dobinsons 80 Series Rear Bump Stop Extensions Kit (1.0-2.0 in)
Both sets are in stock and available now from ExitOffroad.com. Click the product heading just above to go right there.

Both sets have the same main features and benefits:

• Suits all Toyota Land Cruiser 80 Series from 1990 to 1997
• 1″ (25mm) extensions stackable up to two per spot for a total of 2″ (50mm) of thickness
• Durable Solid Steel Spacers
• Sold as a Kit for inner and outer front or rear bump stops
• The inner goes inside the coil spring on the inner bump stop
• The outer goes between the mount and the bump stop on the frame
• Space down your bump stops to prevent shock bottom outs at full compression
• Keep your tires out of your fenders if they’re oversized by spacing down the bump stops
• General bump stop extension guidelines (will vary based on brand of shocks and bump stops used)
  • Dobinsons 0-3″ lift shocks: Extensions are not necessary, unless running oversized tires
  • Dobinsons 4-5″ lift shocks: Front needs about .5″ of bump stop extension, rear needs 2” of bump extension
  • Dobinsons 6″ lift shocks: Front needs about 1.5” bump stop extension, rear needs a 3” extension or 2″ extension with extended length bump stops

What is considered an oversize tire? I'm on 315/70/16

Some guys are running bigger tires (bigger than 35's) and the tires can cut into the inner fenders. You'd just need to check the clearance at full flex to see if you need to limit the up travel.

@crikeymike, what do you recommend to achieve the necessary bump stop extension for 6" lifts since this kit only comes with 2" bump stop extensions and I don't see the "extended length bump stops" on your website?

I can pair the 1" frame extension with a 2" I already have, but there doesn't seem to be an inner coil bump stop extension to get to 3", short of buying two of these kits.

Yes, if you already have +2" extended bump stops, then add the 1" spacer to them instead of buying new ones. Or you can buy longer bump stops from someone like Duro Bumps, these: 3-Inch Extended Rear Bump Stops for Land Cruiser & Lexus LX450 - https://durobumps.com/products/dbrlc525

"Bumping" the bump stop thread again, as these have been selling really well lately. For anyone that has bought them, please post photos of them installed.

I made this blog post to detail how to check how much added bump stop you'll need. Lots of info in there.
