GT wheels are the only aftermarket wheels that meet the H1 spec

Mfg Certification letter

Red SimulockThese wheels are a combination of the best of both worlds. They combine the heavy construction of a Cepek Aluminum wheel and the look of a beadlock without the weekly maintenance (retorquing the bolts) that is typical with real beadlocks. All have 8 x 6.5 inch bolt pattern.

Shown with our exposed CTI 'D' spade hub protection, stock CTIS lines and 17" Goodyear MT/R tires.

The simulock rings are 1/4" thick with an OD of 18.525 and an ID of 14.187.


The Simulock has an aluminum ring welded to it with 6 steel inserts pulled into the ring from the back. The ring has 22 bolts showing, 6 of which are attachment screws, and the other 18 are cosmetic. The 6 attachment screws are longer than the rest and pass through non-threaded holes into the inserts in the ring.


Looking to go to 17's but not loose the look of your 2 piece steel wheels? This is the closest you'll get to the 'Military' look of your old 16.5" Steel wheels.
